details : it has a backing made of high tensile manganese bronze with a
special filling of prescription of solid lubricant inserted with certain angle &
density into the surface and processed with precision finishing. It is mainly
used for high load and moderate speed application.

Bushes & plates can be developed with any specifications as per customers requirements.


applications of oilless bearings
where it is inaccessible or difficult to lubricate bearings.
Where hours for design, assembly and maintenance need to be saved.
Where it is difficult to lubricate bearings due to high low temperature.
Where minimum space is required for bearings.
Where corrosion resistance or waterproofing is required.
Where there is dust in the operating environment.
Where oil contamination is not desired.
Where high load and low speed operation that does not accept lubrication is required.
Where oscillation, reciprocating or frequent start and stop operations that makes lubrication insignificant are required.
Where deterioration of lubrication oil occurs due to non-maintenance for a long time.
