High load capacity with optimized seals for long service life

Hub Unit Gen2

PFI 2nd generation bearings are compact double row units that feature double row angular contact ball bearings or double row taper roller bearings. They offer the same technical benefits as the 1st generation bearings (PW bearing family) with the addition of a locking flange that makes installation easier, reduces the need for assembly tools, and minimizes the potential for errors. The flange ring material is made of AISI-SAE 1055, allowing for the forging of complex final forms as required by the application.

Hub Unit Gen3

PFI 3rd generation bearings are similar to the 2nd generation, but feature an additional flange for even easier mounting and assembly. They also use double row angular contact ball bearings or double row taper roller bearings and are made with AISI-SAE 1055 flange material.

ABS Sensor

PFI hub units are available with or without ABS sensors, and can be supplied with sprocket encoder, magnetic encoder, ABS encoder, or integrated ABS sensors, depending on the application and OEM specifications. They are made from high-grade steel, have high mileage and load capacity, optimized seals, and are sealed and greased for life. They also have low contamination risk, require no maintenance, and are designed to reduce weight by integrating components.
