Details
Special characteristics:
- Primary application in situations of alternating stresses or impact loads and preferred in situations of large swivelling movements;
- All rod end housings are made of forged steel, tempered, extremly high loads resistant and protected against corrosion by galvanisation.
- Rod ends are pressed as standard with DGE_ES-2RS radial-spherical-plain bearing.
- Rod ends from size 15 can be greased subsequently by means of a funnel-type lubrication nipple, and from size 20 by means of a conical grease nipple. Further special grease nipples available on request;
- -2RS lip seals on both sides prevent the penetration of coarse dirt particles inside the bearing.
- Connection dimensions in accordance with DIN ISO 8139 for pneumatic cylinders.
