Typical Applications of nBR Rubber V ring

Manufactured from high-quality Nitrile Butadiene Rubber (NBR), the V Ring rotates together with the shaft and forms a reliable axial seal against the housing face, making it an ideal solution for rotating equipment protection and contamination exclusion.

Compared with traditional radial oil seals, NBR V Rings offer simple installation, low friction, and excellent adaptability, especially in applications where misalignment, shaft vibration, or contaminated environments are present.

FAQ – Frequently Asked Questions

01/

Q1: What is the main function of a V Ring seal?
A: V Rings are primarily used for contamination exclusion and grease retention rather than high-pressure sealing.

02/

Q2: Can NBR V Rings handle pressure?
A: They are mainly designed for non-pressurized or very low-pressure applications.

03/

Q3: Does the V Ring rotate with the shaft?
A: Yes, the V Ring rotates together with the shaft and seals axially against a stationary surface.

04/

Q4: Is NBR suitable for outdoor use?
A: NBR offers good oil resistance but limited ozone and weather resistance. For harsh outdoor environments, EPDM or FKM V Rings may be recommended.

05/

Q5: Can NBR V Rings be customized?
A: Yes, custom sizes, hardness, and compounds are available upon request.

06/

Q6: Can a V Ring replace a standard oil seal?
A: In some applications, yes-especially where contamination protection is more critical than fluid pressure sealing.
