(OP)
Does anyone know how bearing manufacturers go about making the rollers for roller bearings? My company is currently producing a roller vane pump and is looking for ways to take cost out of the rollers. I figured that bearing manufacturers must have figured out the cheapest way to make this type of part. Thanks!

Straight rollers can start with coil drawn to diameter, cut to length, ends pointed, heat-treated, diameter ground.
Each plant or product can have various machines, materials and processes depending on the details, so there are many variations on an answer, I gave the basics.
If I was looking to reduce costs, I would get a few detailed quotes from manufactures who do this type of work. There are various types of info on the net, a search should pull up a few. Good luck.
