alternatives to threebond 1211

[*97GTX*]

Tried NAPA, Pepboys, and Discount Auto Parts no one has it. Is there a Permatex or PermaChem equiviant?

Permatex 'the right stuff'.

Cool, thanks I already have some of that. Ooo' one more question. When sealing the case, do I put sealant around the bearing seats as well or is just the flat case surface?

No do not put sealant under the bearings.

Definately do not put anything on the shaft or housing that will remain there.I know you already got the info,but just wanted to inform everyone why not to do this.I have had lots of training and have certificates from most major bearing manufacturers....

The reason that you do not want to do this is....There is a tolerance left between the inner and outer races,and the balls(or rollers),when a bearing is manufactured and assembled.And your shaft and housing must be within the specified tolerances for the bearing to perform properly and live a long and healthy life.If you were to apply anything that would decrease these tolerances,the final result would be a failure.A tolerance that is too loose will result in the same thing,but usually in a different fashion...I.E:inner race spinning on shaft,or outer race spinning in housing.

When I was in the bearing business,I was called upon for my knoledge in high speed bearings from different branches of the company I worked for.There are bearings that will spin up to 25,000 rpm,with precision,when everything is just perfect.....But these are specially made and very expensive,and for special applications.

I have been in many arguments with people,regarding the ABEC rating of a bearing.Especially with people who think they are getting a better bearing when buying bearings for thier roller-blades,and spend the extra few bucks for an ABEC-7 rated bearing...Your wasting your money !!! The ABEC rating of a bearing has to do with the internal tolerances of a bearing....We are talking tens of thousanth's...And both your shaft and housing must be within that tenths of a thousanths tolerance also....So that when everything is pressed together and assembled....it is dead nuts perfect.....Allowing the proper clearance between the inner race,the outer race,and the contact point of the ball or roller surface.I doubt this can be accomplishied in a plastic wheel...

Keep in mind also.....That seals also require a certain tolerance and surface to ride on.If you have grooves or pit's in your sealing surfaces,they will not seal properly....Be it a crank seal or a trailer wheel seal.

Sorry to ramble on :) ,but just thought I would share some knoledge.If anyone has any further questions regarding bearings or seals...feel free to pm or e-mail me.....

carry-on :)
