Rotary Seals

Rotary Seals – Purpose and Industrial Applications

Rotary seals, also referred to as shaft seals or axial seals, are a crucial component in preventing leaks and protecting systems from water, mud, or dust ingress. Installed on rotating or oscillating components, they help retain lubricant inside the system – a vital condition for the long-term reliability of industrial machinery.

These seals are widely used in agriculture, construction, mining, and automotive sectors.

Types of Rotary Seals and Key Features

Our high-performance rotary seals are engineered for low friction and excellent wear resistance, making them ideal for heavy-duty applications with continuous mechanical movement.

Sliding Seals

Sliding seals consist of two hardened metal rings enclosed within a mounting seat via an elastomer ring made of NBR, HNBR, FPM or silicone (MVQ), with a typical hardness range of 50–70 Shore A.

These seals are perfect for abrasive environments where contamination by sand, dust, or sludge is likely. They’re commonly used in construction machinery, agricultural vehicles and mining equipment.

Shaft Seals (Radial Seals)

Radial shaft seals are designed to keep lubricants inside the system while preventing external fluid intrusion and unwanted leakage. They are suitable for use in hubs, axles, rotating shafts and spindles, offering versatile sealing for dynamic parts.
