Rod U-Ring R14

DESCRIPTION

The U-ring R14 has an asymmetric profile, a shortened inner lip and an additional support edge. This is a rod seal suitable for cylinders with radially restricted installation space, especially telescopic cylinders. R14 has an additional sealing edge that significantly prevents the ingress of dirt and shows very good static and dynamic tightness

APPLICATION
Cilinders with restricted housing
Telescopic cilinders
