Product Details
IKO machined type needle roller bearings consist of a solid outer ring, rollers, and a retainer, without an inner ring. These bearings feature low sectional height, large load ratings, and high rigidity, with most models incorporating seals. Prepacked lubricant is not provided except for double sealed bearings (suffix UU), and proper lubricant must be applied during use. Machined type needle roller bearings are typically used with shafts that do not have inner rings. For optimal performance, a shaft surface finish of 0.2MRA or less and a shaft hardness of HRC 58 to 64 are recommended; if these conditions cannot be met, the use of IKO inner rings is advised.
