V RING 45MM rubber V-ring seal, 45 mm inner diameter, shaft sealing element

V RING 45MM rubber V-ring seal is a contact shaft sealing element designed for rotary shafts with a 45 mm nominal inner diameter. It provides axial sealing by fitting onto the shaft and pressing a flexible rubber lip against a counterface, creating a barrier that helps keep dust, dirt and light splashing liquids away from bearings and housings. The seal is suitable for applications where simple, reliable exclusion of contaminants and protection of rotating components are required without complex installation.

Advantages

The rubber V-ring offers a compact, one-piece design that is easy to install and maintain. Its flexible lip adapts to minor shaft misalignments and surface irregularities while maintaining contact sealing. The V RING 45MM requires no separate housing modification and can operate without additional mounting hardware, providing cost-effective contamination control. Its material composition delivers resilience against wear from particulate ingress under typical industrial conditions.

Suitable for

• Industrial electric motors
• Gearboxes and speed reducers
• Rotating shafts on pumps and fans
• Bearings and bearing housings in light-duty environments
• Applications requiring axial shaft sealing against dust and splashes

Key specifications

• Inner diameter: 45 mm nominal
• Type: rubber V-ring contact seal
• Sealing principle: axial lip contact against a counterface
• Material: elastomeric rubber (flexible sealing lip)
• Temperature and chemical compatibility: typical for general-purpose rubber seals (verify against operating conditions)

How to use

Fit the V RING 45MM onto a clean, correctly sized shaft so the inner bore of the seal slides over the shaft profile until the sealing lip faces the counterface to be protected. Ensure the counterface is smooth and free of sharp edges or burrs that could damage the lip. The seal should be mounted with the lip oriented toward the contamination source; axial positioning is adjusted so the lip maintains consistent contact without excessive compression. Check the seal during initial operation and after the first maintenance interval to confirm correct seating and wear.

Usage recommendations

Inspect the shaft and counterface for nicks, corrosion or heavy scoring before installation and replace the seal if the lip shows significant wear. For continuous elevated temperatures, aggressive chemicals, or high-pressure fluids, select a seal material rated for those conditions. Regularly monitor for leakage, unusual noise or increased bearing temperature, which may indicate seal failure or misalignment.
