V-Ring
Categories : Industrial Parts & Safety Gear
A V-ring is a critical axial elastomer seal engineered to protect bearings and mechanical components from external contamination. Unlike conventional oil seals, the V-ring mounts directly onto the rotating shaft and seals against the counterface (housing), providing a highly effective, flexible, and maintenance-friendly sealing solution for modern machinery. Key Benefits of V-Rings: Superior Contamination Barrier: Prevents ingress of dust, dirt, sand, and water splashes, preserving lubricant purity. Low Friction & Long Service Life: The flexible V-shaped lip applies minimal contact pressure, reducing energy loss, heat generation, and wear on the counterface. Self-Centering Design: Mounted with an interference fit, the V-ring rotates with the shaft, using centrifugal force to deflect liquids and debris away from the seal. Ease of Installation: No specialized tools or tight housing tolerances required, ideal for new equipment and MRO applications. Dry Running Capability: Performs reliably even in applications with minimal or intermittent lubrication.
Back-up Ring
Categories : Industrial Parts & Safety Gear
A Back-up Ring is an essential sealing component designed to be used in conjunction with O-rings to prevent seal extrusion and premature failure in high-pressure, high-temperature, or large-clearance applications. By providing firm structural support to the O-ring, the back-up ring effectively blocks extrusion gaps, ensuring sealing stability, extended service life, and reliable performance under demanding operating conditions. Back-up rings are widely used in hydraulic and pneumatic systems, where pressure spikes and dynamic motion can compromise standard elastomer seals. Available in materials such as PTFE (Teflon) and Nylon, they offer excellent resistance to pressure, wear, and chemical attack, making them ideal for industrial, oil & gas, and heavy-duty engineering applications.
