Sharp edges, nicks and burrs on the shaft must be avoided to prevent damage to the V-ring during installation.
V-rings rotate with the shaft and only require a moderate surface roughness value. As a general guideline, the value should not exceed Ra 6,3 µm (252 µin.). When sealing fluids or exposed to fine, solid contaminants, the V-ring requires a surface roughness value of maximum Ra 3,2 µm (128 µin.).
A V-ring is stretched when installed and fits all shaft diameters within the ranges listed in the product tables.
