e Factor: 0.49. Y Factor: 1.23. Geometry Factor (Cg): 0.134. The e factor is the thrust-to-radial load ratio at which the bearing changes to its thrust-loaded rating equations; the Y factor converts thrust into equivalent radial load in that calculation. An e of 0.49 puts this cup in Timken’s medium-angle group, balanced between radial capacity and thrust capacity.
Maximum fillet radius on the mating housing: 3.30 mm (0.130 in). Housing Backing Shoulder Diameter, frontface (Da): 210.80 mm (8.30 in). Housing Backing Shoulder Diameter, backface (Db): 196.09 mm (7.72 in).
