Benefits :
- Good resistance to lateral forces
- High working speed thanks to the bronze inserting due to its low coefficient of friction.
- Benefit from the rigidity of steel
- Orientation flat to reduce the overall space requirements
Available in 3 tolerance classes for precise matching with the guide bushes according to the need.
Conception : Modular design for an easy integration and simplified maintenance.
- Machining
- Grinding / honing
- Grooving
- Treatment
Target application :
Ideal for press tools, injection moulds or any other assembly requiring precise, reliable guidance.
Recommendation for use :
- Lubrification : Make sure that the bushe is always well lubricated to ensure its efficiency and lifespan. Lubrication is provided by the grease nipple and the grooves inside the bushe.
- Mounting : The bushe is fitted using the clamps and screws directly in the tool plate. It is important to ensure that the pillar is correctly fitted to guarantee the parrallelism with the guide bushes and preventing premature wear.
- Do not exceed working speed. Compliance with working speeds ensures the integrity of the tool and bushe.
- Environment : Do not store or use the bushe in a corrosive environment.
Maintenance recommendations :
- Regular cleaning
- Regular inspection
- Load control
To order you need to indicate :
