Oilless Bearing Technology For:
Improve technology without lubrication
Applications without lubrication and for long service life
Develops oil-free bearings for continuous dry-running operation.
Lowest possible friction and wear values in continuous and intermittent operation
- Extreme environmental conditions
Reduce costs with oilless bearing bushing.
Maintenance fees are caused annually by excessive friction and wear due to inadequate lubrication.
Oilless bearings are an alternative for lubricated plain bushings bearings.
By avoiding lubrication, oilless bushing technology attains superior service life: for high temp at continuous exposure, from cleanrooms to extreme dirt exposure, from vacuum to extreme humidity.
Bronze Flanged Dimensional Stability
Bronze flange bushing made of CuSn8 with Lubrication Indents
Quality/Reliability
Flange Bearing material made of solid bronze strip with indents for lubrication
Flange bronze bushing extended service life
One Piece Compact Design, Split Type
Suitable for Continuous Sliding, Rotating and Oscillating Movement
Metric Size& Inch Size
Self-lubricated technology
Cylindrical bushes available in standard dimensions, also with non-standard dimensions, flanged bushes, sliding plates, customized bearing designs. Bronze wrapped bushings are made of entirely bronze CuSn8. Because of material properties, the working surface rolled with diamond Indentations (standard Indentations) or stamped oil grooves according to detailed application.
The benefits of wraped bronze bearings
Oil Indentations/Holes
Wear resistant wrapped bronze bushing made of CuSn8 strip with perforation for lubricated applications
Improved performance compared with diamond bronze bearings : larger grease holes increase maintenance intervals, dirt and debris swept into perforations, thereby reducing wear.
Bronze bearing performance under relatively high loads and low speeds
Reduce costs with our bronze bearing
Self-lubricated technology
Wrapped flanged bearing types made to order: cylindrical bushes with non-standard dimensions, customized bearing designs. You can also use our self-lubricating bronze oilless parts configurator.
