What is SKF Seals?
SKF Seals is a comprehensive range of sealing solutions manufactured by SKF that protect machinery from leakage and contamination while preserving lubrication. The portfolio covers radial shaft seals (oil seals), hydraulic seals, rotary seals, lip seals, V-rings, and specialized elastomer seals designed for a wide range of temperatures, pressures, and environments. These seals are engineered for precision fit, long service life, and compatibility with many lubricants and media found in automotive, industrial, and machinery applications. RS Components stocks SKF Seals to support maintenance, replacement, and engineered assemblies across sectors such as manufacturing, hydraulics, gearboxes, pumps, and heavy machinery.

What types of SKF seals are available and where are they used?
SKF offers several core seal families tailored to different duty cycles and media. Common categories include:
  • Radial Shaft Seals (Oil Seals): retain lubricants and exclude dirt around rotating shafts in gearboxes, pumps, and motors.
  • Hydraulic Seals: seal hydraulic cylinders in heavy machinery, presses, and industrial equipment, with materials chosen for hydraulic fluid compatibility.
  • Rotary Seals and Lip Seals: seal rotating interfaces in turbines, electric motors, and compressors.
  • O-Rings and Gaskets: provide static and dynamic sealing across a variety of assemblies.
  • Wipers and Dust Seals: protect bearings and internal components from contamination.
  • V-Rings and Mechanical Seals: offer shaft protection and reliable sealing in demanding environments.
The right SKF seal depends on shaft bore and diameter, operating temperature, media (oil, water-based fluids, fuels), speed, and pressure. RS Components carries a broad selection to match OEM specifications or to provide compatible aftermarket replacements.

How do I choose the right SKF seal material for my application?
Material choice affects compatibility, temperature range, wear resistance, and durability. Common SKF seal materials include:
  • NBR (Nitrile), good oil resistance and cost-effectiveness for many hydraulic and automotive applications.
  • FKM/Viton (fluoroelastomer), excellent chemical resistance and high-temperature performance in aggressive fluids.
  • EPDM, excellent for water and steam environments but not compatible with petroleum-based oils.
  • Silicone, high temperature capability and low compression set for specialized needs.
  • PTFE composites, for low friction and broad chemical compatibility in challenging media.
When selecting, consider the media compatibility, operating temperature range, pressure, speed, and the potential for abrasion or chemical attack. SKF data sheets and RS Components technical support can help you identify the best material for your specific machine.

How do I identify SKF seal part numbers and ensure a proper replacement?
Part numbers typically encode size (bore and shaft), profile, and material. To identify a replacement:
  • Measure shaft diameter, bore, and any available recess dimensions or housing details.
  • Consult the SKF catalog or data sheets for the target seal profile (lip height, groove type, and back thickness).
  • Match the original part number when available, or use the SKF code search by dimensions and application type.
  • Cross-check with RS Components product listings and compatibility notes to ensure correct fit for your machine model and region.
If in doubt, provide photos or measurements to RS Components support or refer to SKF engineering data for the exact material and tolerance recommendations.

What are common applications for SKF seals in industry?
SKF seals are used across automotive, industrial hydraulics, machinery, and energy sectors. Typical applications include:
  • Gearboxes and transmissions in heavy equipment
  • Hydraulic cylinders in construction and mining machinery
  • Pumps, compressors, and fans in manufacturing plants
  • Bearings and spindles in textile and paper machinery
  • Food and beverage processing equipment with FDA/EFSA-grade material options
  • Renewables and wind turbine gearboxes and hydraulic systems
SKF seals are selected for reliability, low leakage, and long service life in challenging environments, making them a staple in maintenance and new equipment builds.

How should I install SKF seals to ensure reliability and avoid damage?
Proper installation protects seal integrity and prolongs service life. General guidelines:
  • Clean all mating surfaces and inspect for wear, burrs, and scoring on shafts.
  • Choose the correct installation tool or a properly sized driver to avoid extrusion or tearing of the seal lip.
  • Lightly lubricate the seal lip and installation surface with an appropriate lubricant compatible with the seal material and media.
  • Align the seal squarely with the bore or housing to prevent misalignment or distortion.
  • Apply seating pressure evenly and avoid hammering or bending the seal during installation.
  • Check for smooth rotation and confirm there are no leaks after the initial run-in period.
For critical or high-pressure systems, consult SKF installation guidelines or RS Components technical support for recommended tooling and procedures.

What is the difference between oil seals and hydraulic seals in SKF's lineup?
Oil seals (radial shaft seals) primarily serve to retain lubricants within rotating equipment and exclude contaminants, balancing low leakage with durability under rotating speeds. Hydraulic seals are designed for hydraulic systems and handle higher pressure differentials, typically featuring advanced lip geometries and materials optimized for hydraulic fluids. Both types are available in multiple profiles and materials, allowing engineers to tailor seals to temperature, media, pressure, and speed requirements. SKF provides seals engineered specifically for tolerances, wear resistance, and long-term reliability in both categories.

Can SKF seals be used with all lubricants and media?
Compatibility depends on seal material, temperature, and chemical exposure. Most SKF seals are designed to handle common mineral oils and synthetic lubricants, but aggressive chemicals, solvents, and high-temperature fluids may require FKM or PTFE-based seals. Always check the material compatibility chart in the SKF data sheet and confirm with RS Components support to ensure the chosen seal will perform under your specific media and operating conditions.

What other products related to SKF Seals are available at RS Components?
To complete a sealing solution, RS Components offers a range of related items:
  • and driver kits to protect seal lips
  • seal kits for common machines with multiple sizes
  • O-rings, gaskets, and lip profiles for redundant or static sealing
  • bearing seals and wipers to extend bearing life
  • lubricants and assembly compounds compatible with SKF materials
  • maintenance consumables and diagnostic kits to monitor seal health
If you’re building a maintenance plan, RS Components can help you assemble a complete SKF sealing solution tailored to your equipment.

What should I consider when ordering SKF seals for OEM or aftermarket use?
Key considerations include:
  • Exact seal profile, bore and shaft dimensions, and receiver housing geometry
  • Material selection based on media, temperature, and duty cycle
  • Sealing life expectations and maintenance intervals
  • Compatibility with existing lubricants and adjacent components
  • Availability of seal kits or single-item replacements
  • Lead time and regional availability through RS Components
If needed, request a cross-reference with SKF catalog numbers or RS Components part numbers to ensure seamless sourcing and installation.
