SAF-Holland

This elastomeric circular seal provides a robust barrier against fluid leakage and pressure loss within heavy-duty wheel-end and axle assemblies. Engineered to resist transmission fluids, lubricants, and common workshop solvents, it maintains system integrity across a wide temperature range and under demanding operating conditions. Its geometry, in combination with an optimized durometer, minimizes extrusion under pressure and preserves sealing performance as rotating components cycle through load changes. The result is reduced contamination ingress, longer bearing life, and more predictable braking and suspension behavior. The VMRS code 077-003-015 places this sealing element in the heavy-duty lubrication and sealing family, aligning with numerous SAF-Holland wheel-end configurations that require reliable hydrostatic or dynamic sealing. Compatible with a broad spectrum of SAF-Holland wheel-end and drive-pack installations, it is particularly suited to interfaces where a static or dynamic seal must retain lubricants while excluding dirt, water, and salts. Proper groove dimensions, cleanliness during installation, and correct seating are essential to maximize service life and minimize maintenance downtime in trailer and tractor applications that rely on consistent fluid integrity and vented or sealed assemblies.
