X-ring 25,12x1,78 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

FAQ

What materials are used in the X-ring?

The X-ring is made from NBR 70, which is oil-resistant and suitable for various applications.

What is the temperature range for the NBR X-ring?

The NBR X-ring can withstand temperatures up to approximately 50 °C for oils and up to +80 °C in water.

How does the design of the X-ring affect its performance?

The nearly square cross-section of the X-ring minimizes radial pretensioning and reduces contact stresses, leading to less abrasion.

Expert Advice: Ensure proper installation to maximize the sealing capabilities of the X-ring, particularly in dynamic applications.
