Supporting Roller Bearing NATR17
Demension: 17×40×21mm , Weight: 144g.
SHAPE LOCATION TOLERANCE SHOULD BE TO CURRENT STANDARD;
The supporting roller has the thick-wall outer ring, by which the roller can be rolled directly at the rollway and withstand the large load. The supporting rollers made by our company include STO RSTO, NA222RS,
RN222RS, NATR NARTPP, NATV NATVPP,NUTR NAST. Supporting Roller.
The curve roller is composed of a bolt, thrust collar, outer ring, needle and cage assembly or full complement rolling body. It has the thick-wall outer ring with camber outside face, withstanding the high radial force.The curve rollers made by our company include KR, KRE, KRV, KRVE, NUKR and NUKRE. Model KRPP,

Model NATR supporting roller bearing includes outer ring, inner ring, needle cage assembly and baffle ring pressed and fixed in both sides of inner ring. Model NATR…PP support roller bearing has the seal ring. It has a large grease-storage space and can be used for a long time without adding lubricating grease.
The structure of Model NATV supporting roller bearing is same as that of Model NATR. Model NATV is the bearing with full of needles. It can withstand heavy load under the low speed. However it is necessary to add the lubricating grease at regular intervals. Model NATV…PP supporting roller needle bearing has the seal ring structure.
If the surface of outer ring is cylinder face, the letter X shall be added after designation of bearing.
Model NUTR supporting roller is the double-row roller bearing with full of needles. The outer ring is guided by shoulder. All parts of bearing is enclosed by the seal cover pressed in outer ring to form a complete unit. The seal cover and thrust baffle ring constitute the high-efficient gas seal. This kind of Model NUTR supporting roller needle bearing can withstand heavy load. Because of axial guide in rolling body, it can withstand the stock axial load even in the high speed.
If the surface of outer ring is cylinder face, the designation of bearing is NUYT…X
