Radial lip seal for shaftsRotary Shaft Seals
The standard single-lip radial oil seal — steel-cased with a spring-energised elastomer lip that retains lubricant on rotating shafts.
- Temp
- -40°C to +200°C (FKM lip)
- Pressure
- Up to 0.5 bar (standard lip)
Engineered to prevent leaks
Rotary shaft lip seals — single, double-lip, spring-loaded and high-pressure types — that retain lubricant and exclude dirt on shafts and bearings.

An oil seal earns its keep quietly: it keeps the lubricant where it belongs and keeps grit, water and dust out of the bearing. SealGuard radial lip seals pair the right lip elastomer with a precision garter spring and a rigid steel case for consistent radial force as the lip wears. Double-lip designs add a dust excluder for dirty environments, and reinforced high-pressure variants hold film integrity where standard seals would extrude — extending bearing and gearbox life across the plant.

Radial lip seal for shaftsThe standard single-lip radial oil seal — steel-cased with a spring-energised elastomer lip that retains lubricant on rotating shafts.
Pressure-rated rotary oil sealA reinforced rotary oil seal built to hold a modest standing pressure on hydraulic pump and motor shafts where standard lip seals would fail.
Constant-force garter-spring sealA garter-spring-energised lip seal that maintains constant radial force as the lip wears, for reliable long-life shaft sealing.
Dust-excluding twin-lip sealA twin-lip oil seal whose primary lip retains lubricant while an auxiliary dust lip excludes dirt, water and grit from the bearing.
Reinforced seal for pressure shaftsA heavily reinforced rotary seal with a fabric- or back-up-supported lip that holds elevated casing pressure on demanding shaft applications.
Field-tested guidance from our engineers on specifying oil seals for demanding service.
Set the lip-to-shaft interference with the garter spring — never run a worn or over-stretched spring.
Fit double-lip seals in dusty, wet or splash environments to protect the bearing from ingress.
Upgrade to FKM lips for high-temperature gearboxes and synthetic-oil service.
Specify a hardened, ground shaft counterface (Ra 0.2–0.5 µm) to achieve rated seal life.
Send us your service conditions — media, temperature, pressure and motion — and our engineers will specify the seal that holds the line.
