NJ205EM Brass Cage Reinforced Cylindrical Roller Bearing
This roller bearing has a steel cage, C3 radial clearance, outer ring with central oil groove and three oil holes, and 1:12 tapered bore, suitable for applications carrying radial and oscillating axial loads, such as conveyor belt systems.
If you want to know more details, please feel free to contact us.
The two-piece stamped steel window cage features high wear resistance and spaced rollers, load distribution is even and non-contact to reduce friction, vibration and noise, the cage is guided on the inner ring. For applications where shock loads and vibration are severe or thermal expansion is a factor, the C3 radial clearance for this roller bearing is greater than normal. The bearing's 1:12 tapered bore compensates for shaft bending and accommodates tapered shafts.
