Look for you requirement of qualitive Oilless Bushing Manufacturer in China


High quality precision Oilless Bushing


  • High load capacity Good anti-wearing
  • Low coefficients of friction
  • Good heat conductivity
  • High corrosion resistance
  • Long life and maintenance-free
  • No contaminant by oil or grease


Compared to conventional plain bearings, the oil-free bushings offer superior wear resistance, seizure resistance and frictional properties, as well as increased productivity and are maintenance-free.


Oilless Bushing Structure



1. The initial lubricating film provides initial lubrication to reduce friction.

2. Solid lubricants that are aligned according to the direction of movement of the bearing to form a lubricating film that improves the coefficient of friction and wear resistance.
3. Bronze alloy, provides mechanical strength and improves impact resistance and corrosion resistance.


Oilless Bushing Feature


  • No oiling is required

  • Better wear resistance

  • High temperature applications

  • Profitable

  • Can be replaced with Sintered Bronze / Oilite bearings

  • Maintenance cost reduction.

  • Longer working life

Oilless Bushing Application


  • 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.
