KOYO Bearing NAXR40.Z

Product description of KOYO Bearing NAXR40.Z

KOYO Combined needle roller bearings Cylindrical roller thrust series, KOYO Bearing NAXR40.Z, 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.

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 Cylindrical roller thrust series, KOYO Bearing NAXR40.Z, 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

KOYO Combined needle roller bearings Cylindrical roller thrust series, KOYO Bearing NAXR40.Z, 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.

Needle roller bearings are small in sectional height, there-fore useful in making machinery smaller and lighter. This type of bearing is used in a wide range of machinery. such as auto-mobiles, motor coy as, electric machines, machine tools, aerospace and office equipment,
●Compact, highly rigid and superior in lad carrying performance, compared with other types of bearings.
●Excellent tor carrying oscillating loads; coital and many small Diameter rollers.
●Widely employed in stud type and yoke type track rollers used as guide rollers in cam mechanisms or linear motion units.
Also used in miniature cone-way clutches in the clutch mach-an-isms of of equipment, such as copying machines.
