6909NR  NR Bearing Short Description

6909NR bearing is non-separable bearing. The inner and outer raceways are deep groove type, which can bear radial load and bidirectional axial load. This type of bearing has a small friction coefficient, high limit speed, and various size ranges and forms. Bearings with dust caps on both sides are lubricated for life and require no maintenance. But never wash or heat above 80°C.

6909NR Ball Bearing Features

Deep groove ball bearings with stop grooves can simplify the design of the bearing arrangement because the bearing can be axially positioned in the bearing seat with a stop ring (or snap ring). Can save space.
Deep groove ball bearings with stop grooves are supplied according to the following specifications:
Open type (unsealed) with stop groove, the model suffix is N;
Open bearing with stop ring, the designation suffix is NR;
The bearing has a Z dust cover on one side and a stop ring on the other side. The model suffix is ZNR;
The bearing has a double-sided Z dust cover and a stop ring, the model suffix is 2ZNR

6909NR Bearing Application

The main application areas of 6909NR bearing bearings: aerospace engineering, metal cutting machine tools, steel processing equipment, paper making machinery, cement machinery, environmental protection equipment, agriculture, compressors, motors and generators, construction, and so on. 6909NR bearing is better than any brand bearings currently in bearing performance, lifetime, design, and the use of performance. And have more advantages, such as higher meet rated, lower noise, reducing warranty costs greatly, increasing running time of the machine.
