Oil-Free Bushings, Copper Alloy, Straight, Thin Wall, I.D. F7, O.D. m6
Compact thin-wall straight oil-free bushings (MPBZU) made of high-strength brass alloy with embedded solid lubricant. Bore tolerance F7, outside diameter tolerance m6.
- Select bore d (F7) and length L, then confirm D (m6), wall thickness N, recommended housing diameter (H7) and the reference rotation-stopper screw.
- Fixing with a rotation-stopper screw is recommended. Because the wall is thin, move the screw hole position toward the housing side or reduce the screw size when necessary.
- Operating temperature range: -40 ~ 150°C.
Product notes
Recommended mating shafts for F7 bore types: d8 general use (high load), e7 general use (light load), f8 high accuracy, g6 high accuracy (intermittent operation).
Fixing the bushing with an anti-rotation screw is recommended.
Material: high-strength brass alloy with embedded solid lubricant
