Product Details
The IKO machined type needle roller bearing comprises a solid outer ring, rollers, and a retainer, designed without an inner ring. These bearings feature a low sectional height, large load ratings, and high rigidity, while lacking seals. It is essential to apply proper lubricant during use, as prepacked grease is not included for this series. The GTR series includes full complement bearings with mallet-shaped rollers that are guided by a guide rail and groove to reduce skewing. These bearings are ideal for applications involving heavy loads, shock loads, or oscillating motions. Machined type needle roller bearings typically operate with shafts that do not have inner rings, and it is recommended to maintain a shaft surface finish of 0.2 MRA or less and a shaft hardness between HRC 58 and 64. If these conditions cannot be met, the use of IKO inner rings is advised.
