Details
Special characteristics:
- Primary application in situations of alternating stresses or impact loads and preferred in situations of large swivelling movements;
- Joint ball made of ball bearing steel, hardened, ground, polished and hard chromium plated, ensures a reliable corrosion protection.
- Rod ends are pressed as standard with DG_PB radial-spherical-plain bearing.
- All rod end housings are made of forged steel, tempered, extremly high loads resistant and protected against corrosion by galvanisation.
- Rod ends from size 5-30 can be greased subsequently by means of a funnel-type lubrication nipple. Further special grease nipples available on request.
- Connection dimensions in accordance with DIN ISO 8139 for pneumatic cylinders.
