Product Details
Brand Name: | RNB OR NATURAL | Place of Origin: | China | Model Number: | K90x97x20 |
Product Description
Demension: 90×97×20mm , Weight: 103g.
SHAPE LOCATION TOLERANCE SHOULD BE TO CURRENT STANDARD;
The needle roller and cage assembly is an independent bearing element. The each of needle roller is
guided and caged accurately by the cage. It has the highest load carrying capacity and the high rigid design in the smallest structure and space. The wide distance between two guiding surfaces of cage ensures the accurate guide of needle roller and cage assembly.
Needle roller and cage assembly is suitable for the place where the shaft and housing bore are acted as
the raceway. Under the geographic accuracy shaft and housing bore raceway, the highest rotation precision
can be obtained.
The working clearance in bearing location is dependent on the tolerance of inner and outer raceways,
needle roller difference and working temperature.
As for Model K, K…D radial needle and retainer assembly, this kind of bearing only has a group of radial
needle and retainer assembly. With small outside diameter size, it is suitable for the parts, where the radial sizes are specially limited, used for bearing the radial load. Model K…ZW, K…ZWD radial needle and retainer assembly is the double row radial needle and retainer assembly.
As for this kind of bearing, since it has not collar, the surface of journal and the surface of hole at the
housing are directly acted as rolling surface with surface hardness HRC 60 and surface roughness Ra no more
than 0.63m.
In order to satisfy the requirement of main machine, this kind of bearing can be made in split bearing,
convenient for mounting. Model K D represents as the single row split bearing and Model KZWD represents as double row split bearing.
Radial Needle Roller and Cage Assemblies K90x97x20
(1-1) K single-row radial needle roller and cage assembly
(1-2) K...ZW double-row radial needle roller and cage assembly
(1-3) K... D partial single-row radial needle roller and cage assembly
(1-4) K...ZWD double-row radial needle roller and cage assembly
The rod-use needle roller and cage assembly is mainly used for engine, compressor and other crankguide.
The designation of the rod-use needle roller and cage assembly is composed of letter and number. The
letter KZK represents crank pine assembly and KBK represents piston pin assembly.
5.The needle roller and cage assembly for KZK crank pin adapts M-type cage with reliable performance. It
has special requirement. The surface of cage can be silver-plated or copper-coated.
6. The needle roller and cage assembly for KBK piston pin is different from KZK (external guide for crank
pin). It is internally guided on the piston pin), thus increasing the length of needle.
