A D A Radial and Angular Contact Ball Bearings TIMKEN PRODUCTS CATALOG D41 7304-7318WN 7319-7330WN MBR MEDIUM 7300WN SERIES Dimensionally interchangeable with the radial 300 Series. The 7000WN Product Family includes a refined bore diameter. The 7300WN Series can sustain heavier thrust and combined loads than the 7200WN Series. A single bearing is suggested for applications in which the thrust load is in one direction or, in the case of combined loads, the thrust load is high in relation to the radial load. A duplex pair is suggested for applications where thrust is present in both directions or where axial displacement of the shaft must be restricted. For exceptionally high thrust loads in one direction, a tandem pair can be used, opposed by a third bearing. Size 7303W has a 20 degree contact angle and a steel cage. Sizes 7304WN through 7318WN have a 40 degree contact angle and a one-piece, ball-piloted, pressed brass cage. Larger sizes 7319WN through 7330WN have a 40 degree contact angle and a one-piece, outer ring piloted high- strength machined bronze cage. Sizes 7306WN to 7318WN also available with a one-piece, high-strength, machined bronze retainer. DIMENSIONS - TOLERANCES Bearing Bore Outside Width Fillet Wt.
