| Rugged all-metal design with steel ball retainer for harsh environments and heavy contamination |
| Many pockets acting as lubricant reservoirs for extended lubrication intervals or lubrication for life |
| Seal-free and with steel ball retainers for temperatures well above 80°C or under vacuum |
| With locating hole for axial and radial securing (no locating hole for shaft diameters 12 and 16) |
| Optional integrated wiper seals |
| For use in woodworking, foundries, cement plants |
| Pockets collect any dirt that may have worked its way in to prevent the linear bushing from jamming. |
| No wiper seals, come with integrated steel retaining rings; higher temperatures allowed with shaft diameters 12 and higher |
| Hardened and ground outer sleeve |
| Steel ball retainer |
| Balls made of rolling bearing steel |
