Oiles 80 Oil-impregnated polyacetal bearings Feature Serviceable without the need for lubrication. Has superior load resistance and wear resistance. Features low coefficient 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.

This product demonstrates satisfactory performance at the slide surface roughness of 6.3 to 12.5 mRy. 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. Contact us for grinding and milling information. These are values of the typical grade Oiles 80. The values shown above are typical values, not the standard values. . N/mmo2 kgf/cm2p N/mmo2 kgf/cm2p N/mmo2 kgf/cm2p N/mmo2 kgf/cm2p .
