Product Details
The IKO Shell Type Needle Roller Bearing features a closed end design with a 3/8 inch bore, a 9/16 inch outer diameter, and a width of .375 inches, identified by Part# BAM66. This bearing consists of a precisely drawn thin outer ring made from special steel plate, needle rollers, and may include a retainer or not. Known for their compact size and light weight, Shell Type Needle Roller Bearings provide relatively high load ratings. When equipped with a retainer, these bearings are suitable for high-speed applications, as the retainer and thrust ring guide the rollers efficiently. It is important to note that these bearings do not come with pre-packed lubricant, so appropriate lubrication must be applied during use. They are typically utilized with shafts that lack inner rings, and it is advisable to maintain a shaft surface finish of 0.2?MRA or less, combined with a shaft hardness of HRC 58 to 64. If these criteria cannot be met, the use of IKO inner rings is recommended. Additionally, due to the outer ring's thin cross-section, direct measurement after heat treatment may result in deformation, so standard mounting dimensions should be used for both shaft and housing diameters, with an outer ring width tolerance of +0 to -0.20 mm.
