Product Details
Iko machined type needle roller bearings consist of a solid outer ring, rollers, and a retainer, and do not include an inner ring. These bearings feature a low sectional height, large load ratings, and rigidity, and they come without seals, requiring proper lubrication as prepacked grease is not provided for these series. The GTR series comprises full complement bearings equipped with mallet-shaped rollers that are guided by a guide rail and groove to minimize skewing, making them suitable for applications involving heavy loads, shock loads, or oscillating motions. Machined type needle roller bearings are typically used with shafts that lack inner rings, with a recommendation for a shaft surface finish of 0.2MRA 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 advised.
