Question:

Hello, I have a kaeser m57 210 cfm tow behind air compressor with a missing wheel bearing hub. I am having trouble finding a bearing to replace it. The smaller shaft is 25mm and the larger shaft is 35mm. Do you guys have any hub that will fit. Thanks in advance

I am sorry to say that we do not carry any hubs which will use this exact bearing combination. We do have the # L44643 bearing which has a 1" ID, this will be as close as we can get to a 25mm shaft. We also have a # L68149 bearing that has a 1.378" ID which is basically spot on at 35mm. I am afraid there is no hub available that uses both of these bearings.

Generally we like to get the numbers from each bearing to confirm fitment. If possible, your best bet would be to remove the other hub, unpack the bearings and see if you can see the number stamped on each one. This will help us narrow down what hub you would need. It may be worth seeing if you can get ahold of this manufacturer Kaeser also, as it is possible this hub is proprietary to their trailers.
