manufacturing cost
(OP)
I wonder what might be the difference in manufacturing cost between the following 2 roller chains.
The two chains are identical in everything except the second chain is 30% wider than the first. So they both have the same chain plates, same construction, but the roller, bushing, and pin on the second is 30% longer than the first.
Will it equates to a 30% increase in price?
Thanks

RE: manufacturing cost
Do they think the CUSTOMER would expect it to be much more expensive and so they can charge a much higher price? What's the deal behind it?
When you consider a regular chain and a o ring sealed chain, the o ring chain is slightly wider and has the o ring. But the price is increased substantially.

RE: manufacturing cost
Since the resulting product is substantially better they can charge more for it.
Fortunately most of us live in a rough approximation to a free market, where we are prepared to reward people who make better products.
Oh, and if you don't think the O ring chain is a better product, buy the chep one.
For goodness sake, don't whine about it.

RE: manufacturing cost
Thanks for the help.
So basically the price is often not directly related to the manufacturing cost. In another word, if a product can be made better even if the manufacturing cost stays the same (or even go down), it can still cost more to consumers.
RE: manufacturing cost
I frankly have no idea how prices are set in the retail market.

RE: manufacturing cost
the product price as a rough estimate.
I would expect the price to increase
by 30 percent of 1/3 the total cost plus
some little marginal cost to finish the
extra length of material thru the shop
for the finish grind or whatever.
RE: manufacturing cost
You got it. That's how most companies increase their profitability. They know that they can sell their product for X dollars, so reducing the cost to manufacture that product equals more profit.

I actually saw an operation in New Jersey which unpackaged London Fog coats from Chinese boxes and repackaged into US sourced packaging. The price of the coat was higher because of the brand name. By the way the warehouse was staffed with almost entirely Spanish speaking people and I assume some of these were illegals.
RE: manufacturing cost
Isnt that ^^^^ illegal?
I mean if it says made in china thats one thing, but changing the manufacture origin on something has to violate some trade rule or otherwise.
RE: manufacturing cost
RE: manufacturing cost
RE: manufacturing cost
I didn't say they changed the country of origin but the packaging (box) because the customers and employees first off cannot read Chinese on the boxes but also to not show Chinese product on the their shelves or warehouses. The coats had the "made in China" on the labels inside. This particular retailer has huge automated storage and retrieval warehouses. They proudly show off the warehouses to people taking tours but do not want to show the people how much foreign product (probably greater than 75%) they sell.
RE: manufacturing cost
Lets not forget that some of these "premium" manufacturers have lots of money sunk into these products in Development costs. Maybe it does cost less to mfr, but didn't a team of engineers figure that out (god knows, I don't work for free). And also, the difference between the "quality" discounters and major mfr's are the costs spend developing products that WILL NEVER come to market.

RE: manufacturing cost
I would agree with you but the actually reason for higher prices is lack of competition in that particular market place. Intel who dumps billions into research and development would gladly charge a 50% premium for their processors except for AMD. GM built terrible quality cars and made billions until the Japanese started kicking their butts. Sometimes there is a perception of better quality from some manufacturer but it can be deceiving. Older Harley Davidsons were not the same quality as present day Harleys.
I do not pity the manufacturers who have to invest millions to develop a product. I and the board of directors look at it as an investment and expect a good ROI with some risks associated with its development. The products which never came to market, failed because of bad decision making, poor execution or a mirade of management controlled failures.
RE: manufacturing cost
Good points taken. I agree that in many areas, a healty competition can drive consumer costs down. Many of the tier 2 manufacturers that you point out begain their lives manufacturing products that others have spent time developing. While focusing heavily on manufacturability of a proven product, the risk is lower, thus the product can be offered at a low rate. The OEM then must take steps to maintain a competitive edge, by investing in improving manufacturability or to develop newer better products.
My origional point was to show, in my experience, why the cost of a product may stay the same, or increase, even though the cost to make the product has decreased. This happens in many situations though, not just the ones that have little competion.
In many cases, the cost of both producers increase, as their ad and marketing budges increase, as they vie for market share...
It would be easy if cost of material, or cost of development or any other singular cost would contribute to the pricepoint of a product, but the reality is that a butterfly can flap its wings in China, and the cost of my i-NEW will go up or down for no real good reason (Maybe now that he's retired, Allen Greenspan can tell us all).

It uses actual needle bearings between the pin and the roller instead of bushing. So I'm guessing this chain would be a lot more longer lasting. But since it's not very widely used, I'm guessing it costs significantly more to produce. It seems it's only used on conveying applications where precise displacement is important.
Compared to a regular chain bushed chain, how much more costly will this "needle bearing chain" be in terms manufacturing cost?
Thanks for the help.
RE: manufacturing cost
Autoguru, it doesn't matter what the cost difference is to Tsubaki. They will price the chain according to what they feel the value is -- probably comparable to a high-strength, steel reinforced timing belt.
It may cost them three times as much as standard roller chain to make, but they may very well charge five times as much. If customers perceive the value, then it will sell. If not, they will feel the pressure to lower the price. Basic supply and demand.
Swall - at my company, we call that strategy "go-away" pricing. We'd rather you go away, but if you insist we're going to make sure we make money at it!
RE: manufacturing cost
Usually a normal chain only has a life of 15000 hours under ideal lubrication condition and installation. They needs to be replaced once the elongation reaches a certain limit. But this "needle bearing" design can increase the wear life drammatically so the chain will be limited by its fatigue life.
I'd like to find out more about fatigue life calculation. Do you think a chain can last 50000 hours if there are no pin wear elongation?
Thanks

RE: manufacturing cost
That might not be cost effective if the machine only last twice as long as a normal chain. Normal chains can last up to 15000 hours if everything is ideal. For a machine that has a life of 20000 hour, clearly it's not worth it to get a chain that cost 3 times as much.
So my question is, what are the lives of common industrial machines that uses the chain drive? such as pumps, fans, compressors, ect... (in hours).
Thanks.
RE: manufacturing cost
Typical lives for production machinery are 10000-80000 hours, although the latter is probably unrepresentative.
We still use some pre-war presses, albeit extensively refurbished.

RE: manufacturing cost
I do ask a lot of questions since I'm curious but also because I need the answers.
RE: manufacturing cost
Whether the needle bearing chain is expensive depends on your application and what you are comparing it to. How much does it cost to replace the cheaper chain? If minimizing elongation is a vital part of your selection process, then the higher price for the chain might be insignificant when you compare the alternatives. This company would not be selling this chain if someone did not recognize the value of it. Just because it is more expensive does not mean it is not the better value.
For a car company looking to do things cheap and make money on spare parts and repairs, the needle bearing chain is probably not worth the cost, but to the end user who must do the maintenance, it might be worth much more.
RE: manufacturing cost
Thanks for the star - my first!
I'm not sure I'm qualified to start a whole thread on this subject. I just took a business course a few years ago and we spent a few hours on marketing. Given that I'm pretty cynical about marketing I found the pricing strategies the most interesting and relevant to me.
mbensema: this is one of the things vendors can't seem to grasp with oem companies (like the one I work for). We're not interested in chain with 10 year service life. We just want something that will outlast our warranty! Ditto for so many other types of products - these guys need to sell the end users on this stuff so that they will demand it in the machinery they buy.

RE: manufacturing cost
How much would adding a small idler sprocket add to the cost of a chain drive?
Thanks
RE: manufacturing cost
However much the idler sprocket cost plus mounting/attaching hardware.
RE: manufacturing cost
It's often said that the sprockets are cheap and chains are expensive.
For sprockets, the smaller one will be cheaper.
The idler sprocket will be about the same size as the small driving sprocket but it's not really under any load, therefore I think it can be made more cheaply.
Therefore my rough guess is that the idler sprocket will add no more to 5% of the cost of the drive. But that's only my guess.
