The 69 series is the thin-section family: a 40 mm bore in a 62 mm envelope only 12 mm wide, which is where it earns its place on a compact gearbox or an actuator head. Contact seals rub on the inner ring land, so they hold grease and exclude fine contamination at the cost of some speed capability against an open or shielded bearing of the same size.
Shaft abutment diameter da: 44 mm minimum, 46 mm maximum. Housing abutment diameter Da: 58 mm maximum. Shaft or housing fillet radius ra: 0.6 mm maximum. Calculation factor f0: 15.7.
