Oil Seals and Lip Seals

Lip seals include Oil seals, V-rings, Gamma-rings and PTFE shaft seals for rotating applications with low to medium load or speed.

V-RINGS
V-rings are one-piece all-rubber seals with V-shaped cross-section. The elasticity of the V-ring ensures that its body is held securely in place against the shaft while shaft rotation forces the soft lip against the counterface, forming a tight seal. V-rings are used on shafts and bearings to provide effective seals against water, oils and other media. V-rings have a wide working range with respect to temperature and mechanical stress. Thanks to their flexible design, V-rings are effective in absorbing vibration and axial displacement.

OIL SEALS
Oil seals are one of the most commonly used seals for dynamic sealing tasks. Oil seals are generally used to prevent oil from leaking in rotating applications, but can also be used in special circumstances to seal against leakage of other liquids, gases, powders and granules.

Oil seals (radial shaft seals, Simmer rings) are manufactured to DIN/ISO 3761 standards, with installation conditions as outlined in DIN/ISO 3760.

PTFE LIP SEALS
PTFE seals used as shaft seals in rotary applications usually always have a groove in the profile that acts as oil reservoir.
