Overview
INA NA4900-2RSR-XL Needle Roller Bearing is a compact bearing designed to carry high radial load within a small cross-section. It is suitable for gearboxes, automotive transmissions, industrial links, and pivot positions where space saving and load capacity are both required.
Long, small-diameter rollers are arranged in a cage or full-complement design. Versions with or without inner rings are available, and shaft hardness and surface finish are critical when the shaft is used as the raceway.
Key features
- High radial load capacity in limited radial space
- Supports compact and lightweight designs
- Available with or without inner ring
- Suitable for heavily loaded gears and links
Typical applications
- Automotive transmissions
- Industrial gearboxes
- Compressors and pumps
- Links, pivots, and rocker arms
Selection guidance
Check mounting envelope, inner ring requirement, shaft surface hardness, lubrication, load, and speed range.
