Product Description

1. Needle Roller Bearing with inner ring NA4900  .

Single sided or double-faced sealing HXB series needle roller could avoid soil. The sealing ring is of butadiene acrylonitrile rubber. Its working temperature scope is between minus 30 and 180. Lubricant is No.2 or No.3 high-performance lithium based grease. The longer re-lubricating interval period exists for enough storing lubricant grease space. The inner ring is 1mm thicker than the exterior ring, so sealing ring could work even when shaft moves down. There is lubricant aperture in inner ring in common.  

2. Feature: 
 

• Drawn cup needle roller bearing for applications with high dynamic loads
• Drawn steel outer shell (cup) has a reduced cross-section for use in restricted spaces
• Steel cage guides and evenly spaces rollers for reduced friction, vibration, and noise
• Through-hardened, high-carbon chromium steel rollers for heat tolerance and durability under heavy loads

3. We also can offer following  bearings , please check .
