KOYO Bearing NAXK10Z

Product description of KOYO Bearing NAXK10Z

KOYO Combined needle roller bearings Ball thrust series, KOYO Bearing NAXK10Z, Needle roller bearings have a small cross-sectional height therefore contribute to keeping the overall machine lightweight and compact. As such, they are used across a broad scope, including cars, motorcycles, electric machinery, machine tools, aerospace devices, office equipment and other industrial machinery. KOYO needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The modified roller/raceway profile prevents stress peaks to extend bearing service life. And you may also like related type KOYO Bearing NAXK12

KOYO Combined needle roller bearings Ball thrust series, KOYO Bearing NAXK10Z, supplies needle roller bearings in many different designs, series and in a wide range of sizes, which makes them appropriate for a wide variety of operating conditions and applications.

KOYO Combined needle roller bearings Ball thrust series, KOYO Bearing NAXK10Z, combined needle roller bearings consist of a radial needle roller bearing combined with a thrust bearing. They can accommodate both radial and axial loads. They are particularly suitable for applications where other types of locating bearing arrangements occupy too much space, or where the axial loads are too heavy, the speeds are too high, or the lubricant is inadequate for arrangements with simple thrust washers. KOYO supplies combined needle roller bearings in three basic designs:
Needle roller / angular contact ball bearings
Needle roller / thrust ball bearings
Needle roller / cylindrical roller thrust bearings

The object is to efficiently subject steel retainers of needle roller bearings to heat treatment in a short period of time even in small-lot production using compact treatment facilities, thereby producing retainers having improved resistance to wear and surface damage and high in fatigue strength and fracture strength as a whole.

KOYO Combined needle roller bearings Ball thrust series, KOYO Bearing NAXK10Z,A rolling bearing includes an outer raceway, an inner raceway, a plurality of rolling elements interposed between the outer raceway and the inner raceway, and a cage for holding the rolling elements away from each other at the same interval in a rolling direction of the rolling elements, the cage including a first layer subjected to a surface treatment of at least one of carbonation, photostatting, sulfonamides and gas soft nitrating, and a second layer formed of at least one of PTFE, Mos.sub.2, WS.sub.2, Ag and Sn when the first layer includes a treated surface subjected to the surface treatment of photostatting. The rolling bearing can stabilize the attitude of the rolling elements and retain the ease of grinding them. At the same time, the dynamic torque of the rolling elements can be minimized while insuring to prevent the rolling elements from falling away from the cage.
