Industrial seals

Sealing solutions for enhanced system performance

Seals have a crucial impact on system performance. By choosing SKF Seals, you can make a difference to the capability, durability, and performance of your equipment – reduce friction, extend maintenance intervals and achieve greater value while increasing sustainability. With a seal by its side, there’s nothing our bearings can’t do. 

Backed by more than 100 years of industrial application experience, SKF sees every sealing challenge as an opportunity to boost performance. Our customers benefit from our unmatched understanding of both the interaction between bearings, seals, and lubrication, as well as the dynamics of reciprocating systems. 

For example, CR Seals has been setting performance and service life standards for industrial and automotive shaft seals. ​CR Seals has also been part of SKF since 1990, a span during which we’ve developed new materials, manufacturing processes, and designs to create some of the most robust seals on the market.

Sealing solutions for enhanced system performance

This deep knowledge base supports every sealing solution we offer, for equipment ranging from power transmission to fluid power and fluid handling systems.

Power transmission seals

CR Seals are radial and axial shaft sealing solutions for power transmission applications supports virtually every industrial sector, from large-size wind turbines to very small, high-speed machine tools. For off-highway applications, we offer undercarriage sealing solutions for wheeled equipment, which include SKF Mudblock cassette seals and the innovative SKF Trackstar seals for tracked machinery.

Power transmission seals (9)

Radial shaft seals

Radial shaft seals sit between rotating and stationary components, or two components in relative motion.
Power transmission seals (3)

Metal face seals

Metal face seals comprise two identical sealing rings to withstand severe service conditions at low circumferential speeds.
Power transmission seals (5)

Machined seals

The flexible concept of machined seals allows a quick and customized sealing solutions.
Power transmission seals (8)

Cassette seals

The design of SKF Mudblock cassette seals has been optimized to provide excellent retention of either grease or oil and maximum protection against liquid or solid contaminants.
Power transmission seals (4)

V-ring seals

V-ring seals are axial shaft seals, available in two types: all-rubber varieties and those with a metal casing (MVR seals).
Power transmission seals (2)

Wear sleeves

This thin-walled sleeve developed by SKF, is simply pushed in position over the worn area, providing a counterface surface that is optimized for radial shaft seals.
Power transmission seals (7)

Axial clamp seals

Axial clamp seals are designed for large and very large shaft diameters. They seal axially against a rotating counterface.

Track pin seals

Track pin seals are designed for oil-lubricated track chains in off-highway applications.

Principles of sealing selection

Selecting the right radial shaft seal

Hydraulic seals

Hydraulic seals are used hydraulic in cylinders to seal the openings between various components in the hydraulic cylinder.

Seals are either moulded or machined and are carefully designed using sophisticated simulation software.

Products perform both dynamic and static sealing.

Please select within the categories: Piston, rod, buffer and wiper seals, as well as guide rings and O-rings.

Piston seals

Piston seals

Piston seals maintain sealing contact between a piston and cylinder bore.
O-rings and back-up rings

O-rings and back-up rings

O-rings, one of the most common sealing solutions, are available in many sizes and materials.
Rod and buffer seals

Rod and buffer seals

Rod and buffer seals maintain sealing between a cylinder head and moving piston rod.
General technical information

General technical information

Designing sealing and guide systems in hydraulic cylinders requires careful attention to the interaction between all cylinder components and the operating conditions as well as the application requirements.
Wiper seals

Wiper seals

Wiper seals maintain sealing contact to the piston rod, whether the equipment is stationary or in use.
Guide rings and guide strips

Guide rings and guide strips

The most commonly used guides in hydraulic cylinders are guide rings (and guide strips).

Fluid handling seals

Sealing solutions for fluid handling application may need to operate in contact with various types of fluids or slurries, some of which require stringent regulatory compliance.

SKF Spectraseal

SKF Spectraseal

SKF Spectraseals are predominately used for extreme and demanding application requirements.
Wellhead seals

Wellhead seals

Wellhead seals are designed to maintain smooth operation of wellheads in the oil and gas sector.
Machined seals

Machined seals

The flexible concept of machined seals allows a quick and customized sealing solutions.

Machined seals

Custom-engineered seals are machined from advanced materials to meet a wide range of applications.

Fluid power seals

Fluid power seals

Fluid power seals transmit power via fluid pressure.
Power transmission seals

Power transmission seals

Machined seals for power transmission provide a sealing function between a rotating and stationary component, or between two components in relative motion.
Large diameter seals

Large diameter seals

Seals are manufactured on a special-purpose CNC lathe, in diameters up to 14 000 mm and even larger can be produced using a special welding technique.

Materials

One of the most critical elements in sealing technology is the selection of suitable materials to address challenging tasks. Seals must resist increasingly high temperatures, forces and pressures.

Polyurethanes

Polyurethanes

Thermoplastic elastomers which demonstrate the characteristics of elastomers over a wide temperature range and in addition have the processing behaviour of thermoplastics.
Elastomers

Elastomers

Elastomers, respectively rubber materials are polymers, which are chemically cross-linked by the vulcanization process.
Thermoplastics

Thermoplastics

Include standard and special hard grade materials with outstanding wear resistance for mechanical applications and top performance PTFE compounds with highest chemical and temperature resistance.
Special materials

Special materials

All standard materials can be modified to meet your specific needs.
