| Surface roughness ≤ Ra 0.8 | |||
| PROPERTIES | |||
| Economic solution for bronze bearing application due to a thin wall thickness. High load capability and good stability with low abrasion. Suitable for rough working conditions, good corrosion resistance. Lubrication holes for maximum grease storage and the lowest maintenance intervals. | |||
| RANGE OF APPLICATION | |||
| Agriculture machinery, truck cranes & construction machinery, suitable for impact loads | |||
| MAINTENANCE | |||
| It is a low maintenance bushing material. An initial greasing during installation is necessary, after that periodic greasing with oil or grease is mandatory. The lubrication holes are an excellent lubrication depot and keeping maintenance to a minimum. | |||
| MOUNTING ADVISE | |||
| Housing | Chamfer min. 1.5 mm x 15-45°, for easy bushing alignment | ||
| Shaft | Chamfer 5 mm x 15°, for easy insertion of the shaft | ||
| We advises to use a force fitting mandrel for the installation of the bushing. It might be necessary to apply some grease on the outer surface of the bushing when press fitting it into the housing. | |||
