SKF Seal, 29mm Inside Diameter, 7.5mm Thickness - 30 VA R


This seal is a V-profile shaft sealing element designed to retain fluids and exclude contaminants in rotating equipment. It is MADE from nitrile elastomer, it is intended for use where Compact sealing solutions are required in small-diameter shafts and housings within industrial assemblies.

Features and Benefits:


• Nitrile elastomer resists oil and grease for extended service life
• V-profile lip maintains radial contact to reduce leakage
• 7.5mm cross-section offers stable axial sealing under load
• Robust construction supports frequent shaft rotation and reversals
• Compatible with limited-space housings to simplify assembly

Applications


• Suitable for sealing shafts in automation actuators
• Ideal for small electric motor end-shields
• Used with gearboxes in Compact mechanical drives
• Can be used for rotating connectors in electronics enclosures

What shaft and housing sizes does it suit?


It is designed for shafts with a 29mm bore and housings that accommodate a 31mm outer diameter, matching Compact installations.

How does the material perform with common lubricants?


The nitrile compound offers resistance to typical oils and greases used in mechanical and electrical drive systems, providing effective retention of lubricants.

What sealing behaviour can be expected under reversing rotation?


The V-shaped lip maintains contact during directional changes, minimising transient leakage when shaft direction alternates.

How does the profile affect installation?


The thin V-profile simplifies insertion into tight bores and helps centre the seal on small shafts during assembly.

Are there dimensional limits affecting use in precision assemblies?


The small-diameter geometry is suitable for Compact assemblies but requires matching of shaft and bore tolerances to ensure proper sealing performance.
