Cap Seal

QHW, QHWA

Only one component thanks to omission of the supporting ring, easy installation, good sealing behavior owing to the fact that the sealing edge is moved to the back, spring-loaded sealing lip, integrated dirt scraper on the QHWA.

Specs:

NBR (Natural Rubber), Plain Steel case (depending on size, seals are supplied with either two metal inserts or one)

Max Temperature: -30°C/-22°F – 100°C/ 212°F

Sliding Speed: 0.6 m/s

Max Pressure: =16 bar/232 psi


Application:

Hydraulic oil on a mineral oil basis or hydraulic fluids flammable with difficulty.

Predominantly used for sealing liquid and gaseous media in the case of reciprocating motion. In principle, the structure of these cap seals correponds to that of rotary shaft lip seals yet the radial limb of the metallic support element is nearer to the rod and the sealing lip is considerable stronger. The sealing lip has been kept shorter in order to avoid extreme deformation under the effect of the medium pressure. The spring-loaded sealing lip achieves good sealing behavior if the seal is used in the limit temperature range and even in depressurized condition. The helical tension spring provides a constant seal contract pressure over the entire temperature range. The sealing edge has been positioned with respect to the line of spring action in such a was as to ensure a long service life.
