Need info on bearings and seals

Need info on bearings and seals

Need info on bearings and seals

I need some info to help solve our seal and bearing problems.  First, are there any good reference materials on carbon seal design?  Specifically, I would like to know what the face to face (carbon to ceramic) pressure should be to see if we're in spec.  Secondly, we have a number of motors with sealed bearings that appear to have dried-out grease.  I have conflicting advice from the manufacturer's engineer and a competing manufacturer's engineer as to whether or not I can rejuvenate this dried-out grease with oil.  It seems feasible to me, but the manufacturer says no.  The other guy says, "No Problem."  Who to believe?

RE: Need info on bearings and seals

as i know you can use seal manufacturer's catalogs for select your seal material(for example : Burgman's catalog ).

RE: Need info on bearings and seals

If you have not yet found references regarding particular carbon seal design, there are a number of innovative companies that are making interesting carbon seals.  If you still need the carbon seal info, I guess just post another message here.  I'm new here, so forgive me any forum etiquite breach.

RE: Need info on bearings and seals

I don't believe you can bring old grease back to life using oil.  The greases contain solids and other additives that act as a thickening agent.  Old grease is just the collection of these solids.  Clean the old stuff out and put in fresh grease- it will save you time later.

eBook - Rethink Your PLM
A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
