Bearing Selection

Bearing Selection

Bearing Selection

(OP)
First off, a preemptive thank you for anyone willing to help.  I'm trying to find a maintenance-free bearing that will handle axial and thrust loads.  I suppose an ideal solution would be a sealed, sheilded tapered roller bearing, but I can't find any.  Shaft dia: about 1", low speed, 2000 lb axial load, unknown (but low) thrust load.  Any tips would be greatly appreciated.

RE: Bearing Selection

I normally assume "axial" and "thrust" to be the same.  Which is the "radial" load?

RE: Bearing Selection

Tapered roller bearings don't ordinarily come with seals or shields.  Ball bearings often do.

If the 2000 lb is a radial load, you should have no trouble finding one that will deal with it.  

For 2000 lb axial ( := thrust ), you'll need a bigger ball bearing.

RE: Bearing Selection

Timken offers sealed tapered roller bearings in a TSL sealed version, other brands too. L44643/l44610 is available sealed and is 1" bore . I think the combined number with seal is l44600LA

RE: Bearing Selection

SKF (or similar) angular contact ball bearings are another option.  They are available with shields.  You need to verify load capacity.   

RE: Bearing Selection

I only know of INA making angular contact bearings with shields or seals, but are all metric

RE: Bearing Selection

If the thrust load (aligned with the shaft) is low compared to the radial (90 degrees to the shaft) load, any suitably-sized ordinary deep-groove ball bearing with seals will do the job.

RE: Bearing Selection

The phrase "maintenance free" should ideally be accompanied by a description of the environment/application. Also, how much life are you expecting? The replies will be more helpful that way.

Also, I agree with BrianPeterson. Most radial ball bearings can withstand small thrust loads anyway.

 

RE: Bearing Selection

(OP)
Wow....thanks for the quick responses.  As clarification:  2000 lbs radial load, with lower thrust load.  Environment is on the tarmac at naval air stations, so probably pretty clean environments.  Lifetime:  not really sure.  I'm just trying to select something that would require as little maintenance as possible, while trying to keep the lifetime logistics (replacement) cost down as well.  I would be very happy to select a deep-groove ball bearing, but any info on how to estimate allowable thrust loads would be greatly appreciated.  Otherwise, I could go with angular contact bearings, but I run into the same problem with ratings.

RE: Bearing Selection

Get a bearing catalog.  Study it.  All the material you need is in there.

Get a couple of different catalogs; some of the presentations are more easily comprehensible.

These are commonly used in hevy duty caster wheels with a lube fitting.

Thank you to all, esp: BrianPetersen & imcjoek.  I think I'm going to go with a double row angular contact ball bearing with double seals.  Cheap and (hopefully) effective, and likely easily replaced once the bearing has run through its life cycle.

RE: Bearing Selection

I have used DRAC bearings in the past and they worked well, even in dirty environments.  Just be sure to get sealed and not shielded.

electricpete, funny!
