Description:
- Drawn Cup Needle Roller Bearing features a deep drawn, thin-walled outer ring. They are compact bearings with high load carrying capacity and stiffness.
- These bearings are especially suitable for high dynamic loads or radial-limited installation. They are mounted with a tight interference fit in the housing.
- Shoulders or snap rings are not required to locate the bearing axially, thus enables a simple and economic design of the housing bore.
- For various applications such as planetary gears in automobiles, constant mesh gearboxes, agricultural and construction equipment, pumps and compressors, and two-cycle engines, among others.
NOTE:
- Install with a press machine or special tools instead of hammers because beating may lead to local deformation or brittle fracture.
