X-ring 21,95x1,78 NBR 70
NBR X-rings are 4-lipped twin-action static seals with a cross-section shape that is almost square. The NBR oil-resistant X-rings achieve their sealing capabilities by being mounted and compressed inside an assembly axial or radial accommodation. The stress of the medium reinforces the sealing function under severe working circumstances.NBR X-rings have good chemical strength to mineral oils and greases, Hydraulic oils H, HL, HLP, HFA, HFB, HFC to approx. 50 ° C and in water up to + 80 ° C
The NBR X-rings offer a good degree of stabilization as well for dynamic application, as the X-ring owing to its nearly square cross-section is not prone to swinging within the loop curling. NBR X-rings involve less radial pretensioning. Due to the reduced contact stresses, this results in less abrasion. A lubricant reservoir between the binding teeth can be developed because of the design of the NBR X-rings
