Product Description
The needle bearing NA4902 has thin cylinders as rolling elements and can absorb high radial forces with its massive bearing rings. It is suitable for space-saving installation.
Features: - suitable for high radial loads
- require a small radial assembly space
- condition for the use is a hardened and ground shaft
- with an annular groove and lubrication holes in the outer ring
- allows axial displacements - depending on the width of the raceway on the shaft
- material: chrome steel (Cr15)
- temperature resistance: from circa -20 °C up to +120 °C
Application Field:
Needle roller bearing types: can be divided into two structures with inner ring (NA) and without inner ring (RNA).
1. Needle roller bearings with stamped outer rings. There are two types: perforated and sealed. Scope of application: Stamped outer ring needle roller shafts with cages are mostly used in gearboxes of machine tools, automobiles, and motorcycles or textile machinery. The stamped ferrule needle roller bearings without cage are used in the frame of the aircraft and the shaft end of the main wing of the missile.
2. Entity ferrule needle roller bearings Scope of application: mostly used in machine tools and automobile gearboxes.
3. Roller needle roller bearings Scope of application: printing machinery, pasture machinery, agricultural machinery, rollers for guide rails of CNC equipment, conveyor lines, etc.
4. Needle roller and cage assembly. Scope of application: mostly used for large and small ends of connecting rods of gearboxes, motorcycles and automobiles
