Oiles 80
Oil-impregnated polyacetal bearings
Feature
Serviceable without the need for lubrication.
Has superior load resistance and wear resistance.
Features low coecient of friction and superior speed characteristics.
Prevents stick slips and squeak noises.
Injection-molded and can be made in complicated shapes. Good mass
productivity.
Standard products and materials for machining are available in various sizes.
For a low volatile organic compound type, Oiles 80-LVF is available on order.

Machining accuracy (bushing)
Classes here are in JIS standard.
This product demonstrates satisfactory
performance at the slide surface roughness
of Rz6.3 to 12.5
μ
m.
Dimensions may change due to thermal
expansion, chucking pressure, moisture
absorption deformation, etc. High accuracy
is ensured if the product is installed on the
housing and then ground.
Attention should be paid to dimensional
variances due to thermal expansion,
chucking, and bend of the material.

The Oiles 80 bushings are injection-molded.
●
The inner diameter tolerances are the values after pressing into a ring gauge of
φ
D
±
0.002.
●
A stopper is needed at the temperature of 0˚C or less, since the bushing is dislocated due to thermal shrinkage.
