Product Description

High Quality Machine Needle Roller Bearings with Inner Rings NA4909 NA4909LL/3AS

Product Description
Inch style needle roller bearings provide a large load rating in a small space and can be used with or without inner rings. They are available in caged or full complement style. The full complement style is best suited for low speed or oscillating motion while the caged type is better for high speed applications. Load ratings are higher for full complement style bearings. For fitting accuracy the caged type is advantageous when fitting errors and shaft bending are relatively large. They are available with open or Closed ends.

Features

1. The needle roller bearing with or without inner ring is a complete unit consisting of a machined outer ring, a needle roller and cage assembly and a separable inner ring. 2. Due to the small section height, it has a space-saving structure; 3. The outer ring has a lubricating oil groove and lubricating hole. 4. Needle roller bearings with inner rings are used in applications where the shaft cannot be used as a needle roller bearing raceway. 5. Needle roller bearings with inner ring are used in applications where bearings without inner ring cannot be used, or applications where hardened or ground shafts are uneconomical. Bearings with inner rings only allow axial displacement of the shaft relative to the bearing seat within a certain range. If the allowable axial displacement provided by a standard inner ring is not enough, a widened inner ring can be used.

Benefits for Bearing

1. The sensitivity of bearing deformation to load changes is less than that of hydrodynamic bearings; 2. Only a small part of the normal operation requires a certain amount of lubricating oil, which can provide lubricating oil for a long time during the operation; 3. The axial dimension is smaller than the traditional dynamic pressure bearing; it can bear the combined load of radial and thrust at the same time; 4. In the range of large load speed, the unique design can obtain excellent performance; bearing performance is relatively insensitive to fluctuations in load, speed and operating speed.
