Check these three points first
Shaft size alone does not guarantee a fit. These three checks prevent units that arrive and do not match the existing frame.
-
Shaft diameter
Measure the actual shaft, not the old part number. Note the locking type: set screw, eccentric collar or adapter sleeve.
-
Bolt spacing & mounting
Pillow block, flanged or take-up frame. Give the bolt centre distance and centre height so the unit drops into the existing frame.
-
Operating environment
Dust, water, washdown, load and running hours decide the seal design and bearing series.

Where this bearing runs
Typical equipment and industries for this unit, from belt conveyors and bucket elevators to pulley shafts in mines, ports and cement plants.
01 Overhead Conveyors Overhead and trolley conveyors run on many small bearings in trolley wheels, chain guides and turn wheels, with flanged units on drive and take-up… See the application
02 Power Transmission & Gearboxes Mechanical power transmission systems, including reducers, gearboxes, couplings and gear drive sections, depend on tapered, cylindrical, angular contact and spherical roller bearings to carry… See the application
03 Roller Conveyors Roller conveyors in warehouses, distribution centers and production lines use large numbers of small deep groove ball bearings in the rollers, plus pillow block… See the application What maintenance teams report
"We had a repeated failure on a take-up bearing position. Their engineer suggested a heavier unit with a triple-lip seal. We installed it three months ago and it is still running cool. They also supplied all the other bearings we needed for the shutdown."
Robert JohnsonJohnson Grain Terminal, USA "Identifying an old flanged bearing unit on an overhead conveyor was tricky. We sent photos and bolt spacing measurements, and they matched the exact unit within hours. They also supplied the matching deep groove bearings for the drive motor at the same time."
