Germany Merkel - shaped seals SRC type

 
Features

Static ring shaped structure, both sides face a two blade-shaped sealing edge.

Product Benefits

■ Since the position of the sealing lip in the groove, so that the stress distribution is desirable

■ pulsating encounter high pressure peaks, we can firmly maintain the shape of the cavity in the

■ used material is resistant polyurethane extension

Recommended Applications

■ Hydraulic control and adjustment means

■ hydraulic hammer

Design Notes

Use a countersink drill ships can create a cavity on both sides of the trench allows higher roughness.

Surface machining precision
