NJ2309 Bearing, a Single Row Cylindrical Roller Bearing, is Offered by ITS
NJ2309 bearing--single row cylindrical roller bearing
As a top quality bearing manufacturer and supplier in China, ITS team has been engaged in manufacturing bearings and international trade for more than 20 years with excellent after-sales service and quick response. ITS produce high-quality NJ2309 bearing, which is a type of cylindrical roller bearings.
This NJ2309 bearing is a single row cylindrical roller bearing, which has 1 flange on the inner ring, an optimized internal design, a window-type machined brass cage and a greater than normal radial internal clearance. The bearing's dimensions are 45x100x36.
Here are more detailed dimensions of NJ2309 bearing:
d | 45 mm | Bore diameter |
D | 100 mm | Outside diameter |
B | 36 mm | Width |
d1 | ≈64.4 mm | Shoulder diameter of inner ring |
D1 | ≈83.2 mm | Shoulder diameter of outer ring |
F | 58.5 mm | Chamfer dimension of loose flange ring |
r1,2 | min.1.5 mm | Chamfer dimension |
r3,4 | min.1.5 mm | Chamfer dimension |
s | max.3.2 mm | Permissible axial displacement |
Cylindrical roller bearings can be used in applications faced with heavy radial loads and high speeds. Accommodating axial displacement (except for bearings with flanges on both the inner and outer rings), the bearings can offer high stiffness, low friction and long service life.
Cylindrical roller bearings are also available in sealed or split designs. In sealed bearings, the rollers are protected from contaminants, water and dust, while providing lubricant retention and contaminant exclusion. This provides lower friction and longer service life. Split bearings are intended primarily for bearing arrangements which are difficult to access, such as crank shafts, where they simplify maintenance and replacements.
