D A BALL BEARINGS D22 TIMKEN PRODUCTS CATALOG MEDIUM 300K SERIES A heavier cross section than the 200 Series. Capable of carrying considerably heavier radial, thrust and combined loads for a given bore size. Capable of withstanding heavy shock loads. A ball bearing of heavier cross section is rarely required. Uses Conrad-type bearing that is well-balanced, with deep races and uninterrupted race shoulders. Electric motor quality where quietness is a requirement. DIMENSIONS - TOLERANCES Bearing Bore Outside Width Fillet Wt.
