Description

The WEL wiper type is commonly used in simple effect cylinders open on one side. Because of its cleaning function, a reverse profile wiper is used to prevent bore wearing which may be caused by atmospheric agents, condensation and other environmental conditions. The proposed material is a “C0” type polyurethane, with high elasticity modulus, low compression-set and high abrasion resistance. The hardness is 93 Shore A ± 2. Compound reference: C0 The assembling is done by overlapping in semi-open groove with a chamfer preventing the wiper extrusion during the cycle inversion. It is important to remove flashes or cutting edges to avoid damages.
