Availability of Trailer Bearing L44643 and Race L44610


I was looking for a bearing set for a mower spindle. The old bearings are Timken L44610/L44643 . These numbers came up on your site, but they are not Timken. My question is, my mower will run much faster than a wheel bearing. Would this bearing hold up to the high speed and is the bearing you have the same size as the Timken? Thanks


Expert Reply:

The numbers you listed are standard bearing numbers. Typically Timken does not use them, but if that is what you have then most likely the bearing part # L44643 and the seal # L44610 would work well for you.

You can measure to verify though. If the inner diameter of the bearing you have is exactly 1.00 inch then it is the same bearing.
