ENVIRONMENTAL TYPE HYDRAULIC
PRESSURE PUMP SELF-LUBRICATING BEARING
|
|
The product
is developed according to the high PV value of hydraulic
pump. It can offer the low friction coefficient and
good anti-abrasion, be used in semi-dry condition. The
product is applied to medium, high-pressure gear pump,
ram pump, vane pumps, etc. Because of without lead,
the bearing has clean lubricating condition and accord
with environmental requirement.

ENVIRONMENTAL TYPE SHOCK
ABSORBER SELF-LUBRICATING BEARING
|
|
The product
is developed according to reciprocating motion of shock
absorber and high pressure in flank. It can offer low
frictioin coefficient and good anti-abrasion, be used
to semi-dry condition. The product is applied to shock
absorber of automobiles and motorcycles and pneumatic
cylinder. Because of without lead, the bearing has clean
lubricating condition and accord with environmental
requirement.
