Product Details

Craft bearings are split cylindrical roller bearings, which combine all the advantages of conventional antifriction roller bearings with the added feature of being easily assembled around a shaft.

Engineered in halves to ease installation, inspection, and/or replacement of pillow block bearings without removing or disrupting other elements of the system
Cartridge and housing assemblies made of quality ductile iron
ID of housing is spherically machined to accept cartridge assembly
Base-to-center height meets and is sometimes less than industry standard
All hardware used in assembly of the Craft pillow block is of American standard type
Bearings, cartridges, and housings of same series and grouping are interchangeable
O.D. of cartridge is spherically machined to accommodate initial shaft misalignment, allowing bearing and cartridge assembly to align externally
Seal remains on parallel axis with shaft, maintaining a 100% seal along shaft

The side pusher screws must be backed off before attempting to remove outer races
