Load ratings, per row

Dynamic Radial Load Rating C1, at 1 million revolutions: 84,500 lbf (376,000 N). Dynamic Radial Load Rating C90, at 90 million revolutions on the Timken life method: 21,900 lbf (97,500 N).

What these specs mean in practice

K Factor: 0.79. K is the ratio of radial to axial capacity, and a K below 1 marks a steep contact angle that carries a high share of thrust for its radial rating — useful in gear and pinion positions where the axial component is large. Effective Center Location: 0.52 in (13.2 mm), the point from which shaft and bearing spacing are calculated. G1 Factor: 237.1. G2 Factor: 44.6. Geometry Factor (Cg): 0.131, used in the lubrication life adjustment factor a3l.

Mounting dimensions

Maximum shaft fillet radius: 0.14 in (3.600 mm). Shaft backing shoulder diameter, frontface (da): 5.65 in (143.5 mm). Shaft backing shoulder diameter, backface (db): 5.87 in (149 mm). Cage location relative to backface (Aa): 0.28 in (7.1 mm). Cage location relative to frontface (Ab): 0.21 in (5.3 mm). Weight: 38.27 lb (17.357 kg).
