SAR2 Self-lubrication Type Radial Spherical Plain Bearing

Self-lubricating type spherical plainbearings

Self-lubricating spherical plain bearings are primarily intended for situations where a long life, free from main­tenance and lubrication requirements, is desired. They are also used in parts of machines where lubrication would be difficult.

In the self-lubricating spherical plain bearing a self-lubricating PTFE based liner is securely bonded to the outer ring.

Therefore, lubrication, maintenance and inspection are necessary. As there is no oil staining, the bearing is always clean.

It is particularly suitable where the load works in one direction only or where there is a low frequency of oscillating movement.

The inner ring is made of high carbon chromium bearing steel and its sliding surface is hard chromium plated.

Where higher pressures are involved, a special type of spherical plain bearing with a steel mesh reinforced liner is available. Please contact us for details of this item.

The following types of spherical plain bearings are available:

SAR 1 Series    : Equivalent to ISO "E" series

SAR 1 • -SS Series : Equivalent to ISO "E" series,
with seal

SAR 2 Series : Inch series

SAR 4 Series : Special dimension series

All of these types are suitable for a temperature range of -50^oC (-58⁰F) to +100^oC (+212⁰F).
