Measured them upon arrival. The 45x50x32 mm specs are accurate. Great for precision machinery.

Perfect Fit for Industrial Pump
Installed these on a hydraulic pump shaft. Dimensions were spot on and the self-lubricating feature saves maintenance time.

Good Quality, Slow Shipping
The bearing itself is robust and well-made. Took a bit longer to arrive than expected but worth the wait.
