Because of this construction, it is possible to incorporate a greater number of balls than in the deep groove nonfilling notch bearing. the combination of maximum ball complement and the angular contact feature reduces the specific ball loading under thrust load, resulting in high thrust load carrying capacity. MRC 7000 Series angular contact bearings should be used in applications in which the thrust load is especially heavy and beyond the capacity of singlerow types; for example, for a vey heavy thrust load in one direction, or a heaby thrust load in one direction combined with a radial load. Cage Types and Materials: For normal usage: heavy stock, two-piece steel formed pockets, with turned-over fingers or riveted together. For severe vibration, very high speeds, or high operating temperatures: one-piece machined construction of suitable material (phenolic composition, bronze, or special material riding ground O.D. of inner ring). 7300 series bearings have the same ring and ball cage construction as the 7200 Series but are heavier sectioned bearings with a ball complement capable of handling heavier loads. 7300 Series are listed with bore sizes from 10 mm to 280 mm. For two-directional thrust loads, use duplex bearings. 7000 Series bearings are single-row 29° angular contact bearings having one heavy race shoulder and one counterbored race shoulder on the outer ring.
