Special characteristics:
- For high speeds, wide swivelling angles or rotating movements. In contract to the cage design, the full complement design is suitable for higher loads but with a lower speed threshold.
- High loads,
- Mainly all rod end housings are made of forged stainless steel, extremly high loads resistant and surface electropolished which ensures you a very high corrosion resistance.
- Low maintenance due to long-term lubrication with food-grade approval; the rod ends can be greased subsequently by means of a funnel or conical grease nipple. Further special grease nipples available on request;
- Covering discs in stainless steel on both sides to prevent the penetration of coarse dirt particles inside the bearing.
- Connection dimensions in accordance with DIN ISO 8139 for pneumatic cylinders.
