Product Details
The IKO machined type needle roller bearing consists of a solid outer ring, rollers, and a retainer, designed without an inner ring. These bearings feature a low sectional height, large load ratings, and rigidity, with most units including seals; however, prepacked lubricant is not provided except for double sealed bearings, indicated by the suffix UU. It is essential to apply proper lubricant for effective use. These machined type needle roller bearings are typically utilized with shafts lacking inner rings, with a recommended shaft surface finish of 0.2 MRA or less and a shaft hardness of HRC 58 to 64. In cases where these specifications cannot be met, the use of IKO inner rings is advisable.
