Koyo B-57 Inch Series Open Ends Round Bore Uncaged Drawn Cup Needle Roller Bearing, 5/16 in Dia Bore, 1/2 in OD, 1 Row, 7/16 in W, 1420 lb Dynamic/1820 lb Static Load
Drawn Cup Needle Roller Bearings supports radial loads and reduce friction between rotating components, with a drawn outer shell serving as a raceway for the rollers. The small cross section of the drawn cup bearing provides high load-carrying capability with minimum required space. Drawn cup bearing are easily installed with a press fit in the housing.

IKO TLA1516Z Metric Series Caged Shell Standard Needle Roller Bearing With Dust Cover, 15 mm Dia Bore, 21 mm OD, 1 Row, 16 mm W, 9330 N Dynamic/12900 N Static Load
IKO manufactures a wide range of radial Needle Roller Bearings to meet the needs of different applications and machine profiles. These include shell type bearings, needle roller cages for both general use and within engine connecting rods and machined type Needle Roller Bearings. Shell type Needle Roller Bearings are lightweight, low profile motion components designed to handle either high speeds or heavy loads, depending on the configuration. An outer ring made of high strength steel enables a streamlined profile with the lowest sectional height of all the Needle Roller Bearings.
