Spherilastik Bearings
Features / Applications
A heavy duty flexible bearing which combines highload carrying capacity with the ability to accommodate torsional and angular movements in all planes without lubrication and metal-to-metal wear.
Spherilastik bearings with through holes or solid centre members are available in a range of sizes as detailed in this leaflet.
Typical uses include traction and braking reaction rods for rail, road and off-road vehicles, hydraulic damper fixings and other applications where a high duty bearing of compact size is required.

General guidance notes for selection:
1. Properties quoted for the components in this leaflet relate to continuous steady loading or deformation conditions.
2. For continuous dynamic cyclic loading or deformation, the maximum values should be reduced to approximately 30% of the figures quoted, depending on frequency.
3. For medium and low incidence loading and deformation, the tabled values may be increased up to 2 to 3 times.
4. Combined stressing in the different modes and the effects of stress reversals may require a more critical assessment.
