Radial spherical plain bearing, requiring maintenance, inch sizes

Radial spherical plain bearings are designed to accommodate radial and combined radial and axial loads, and also misalignment.

This specific design includes a steel/steel sliding contact surface combination. The bearings require maintenance and can be relubricated via lubrication holes and an annular groove in both rings.

  • Designed for radial and combined radial and axial loads
  • Suitable for heavy static, alternating or impact loads
