Drystar Outline

SO#936FR
Lead FreeRoHS██Precautions for use• Do not grind the bushing inner surface or the outer
diameter to change the size.

██Features
It is the bearing which has sintered porosity of bronze powder
on the steel back plate, with improved self-lubrication andwear resistance by adding polytetrafluoro-ethylene (PTFE),
which has small friction coefficient, and special filler throughimpregnation.

• Polish the surface of the mating surface to the value better
than 3 μ mRmax.
• Offset the joint of the bushing as far as possible from themaximum load point.

• Lead-free bearing which can be used without lubrication.

• To press fit the bushing, press fit it vertically into thehousing.

• Excellent sliding performance under high load and impactload.

• Special lock is not required for Drystar.

• Excellent in wear resistance and long life.

• Initial lubrication can make the product life longer.

• Suitable for sliding motion and continued motion Stick-slip
hardly occurs. Silent operation can be achieved.
