Sealing solutions for enhanced system performance

Seals have a crucial impact on system performance. Life and reliability of what is often considered a simple component can make all the difference to your product and operations. With SKF, you get support for all the key aspects of your sealing system. For the last 110+ years, 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.

IN FOCUS

PRODUCTS

Radial shaft seals

Radial shaft seals sit between rotating and stationary components, or two components in relative motion.

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.

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.

Track pin seals

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

Metal face seals

Metal face seals comprise two identical sealing rings to withstand severe service conditions at low circumferential speeds.

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).

Axial clamp seals

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

Principles of sealing selection

Selecting the right radial shaft seal

PRODUCTS

Piston seals

Piston seals maintain sealing contact between a piston and cylinder bore.

Rod and buffer seals

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

Wiper seals

Wiper seals maintain sealing contact to the piston rod, whether the equipment is stationary or in use.

Guide rings and guide strips

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

O-rings and back-up rings

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

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.

PRODUCTS

SKF Spectraseal

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

Wellhead seals

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

PRODUCTS

Fluid power seals

Fluid power seals transmit power via fluid pressure.

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

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.

The SKF SEAL JET DD system - What distribution has been waiting for

CNC technology to custom-machine seals on a just-in-time basis.

PRODUCTS

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

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

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

PRODUCTS

Materials development

SKF has the capability to design seals in a wide range of materials across elastomers, polyurethanes, thermoplastics and speciality materials.

Testing and analysis

Data from thousands of seal tests conducted annually feeds SKF’s database.

System knowledge

Material development, product and process design engineering, testing and proprietary software.

Manufacturing flexibility

Whether large volumes are required or a single seal for a range of standard or customized seals.
