Heavy Duty Shaft Seals

High‑performance radial lip seals engineered for rotary shafts operating in mission‑critical environments such as marine systems and steel processing equipment.

Designed to protect essential components including bearings, rotary joints, and gearboxes, these seals ensure lubricant retention, contamination prevention, and maximum uptime even under extreme conditions.

Temperature Range

Performs reliably across a wide temperature spectrum

High-Speed Capability

High-speed profiles

up to 100 m/s

Installation

Split seals for quick replacement without removing the shaft

Eliminate Leakage

Protects bearings from contamination and premature failure

Seal Designs & Features

Our seals combine robust materials and smart design to deliver consistent sealing under high loads and speeds:

Elastomeric lip provides dynamic sealing against the shaft
Fabric reinforced rubber back delivers robust static sealing in the housing
Stainless steel spring maintains uniform lip contact at high speeds
PTFE enhancements lower friction, prevent stick slip, and protect the lip during dry running
A large contact area prevents leakage, reduces heat generation, and avoids shaft damage
Handles high speeds and pressures

Engineered for your application

Design possibilities:

Profiles for 0–5 bar / 70 psi pressure
Helical or “V” spring designs
Fabric rubber, full rubber, or self-retaining with metal reinforcement
Endless and split seals for quick replacement without shaft removal
On-site bonding technology for pressurised applications
PTFE liner for ultra-low friction
High-speed profiles (>100 m/s)
Seal kits designed for full system alignment, spacing, and optimal sealing performance
