Product Details
The IKO shell type needle roller bearing, part number BA810ZOH, features a 1/2 inch bore, 11/16 inch outer diameter, and a width of .625 inches. This bearing, often referred to as a drawn cup, is constructed with an outer ring made from accurately drawn thin special steel plate, needle rollers, and may include a retainer. Known for having the smallest sectional height and weight among needle roller bearings, it also offers relatively high load ratings. The version with a retainer is suitable for high-speed applications due to the precise guidance of the rollers by the retainer and thrust ring. Notably, these bearings do not come pre-packed with lubricant, thus necessitating proper lubrication upon use. IKO shell type needle roller bearings are typically employed with shafts that lack inner rings, with a recommended shaft surface finish of 0.2µm RA or less and a hardness of HRC 58 to 64. In cases where these conditions cannot be met, the use of IKO inner rings is advised. It is important to note that the accuracy of the outer ring cannot avoid deformation from heat treatment because of its thin cross-section, making direct measurements on the outer ring inappropriate. Instead, standard mounting dimensions for shaft and housing diameters should be used, with an outer ring width tolerance of +0 to -0.20 mm.
