SKF
Seals
SKF seals serve a simple but crucial function: keeping lubricants in and contamination out. Positioned between rotating and stationary machine components, seals are the critical barrier that determines whether bearings and mechanical systems achieve their design service life or fail prematurely. The SKF seals portfolio spans radial shaft seals (for rotating shafts), axial seals (for static and dynamic face sealing), hydraulic seals (for cylinders and fluid power systems), power transmission seals, fluid handling seals, and specialized automotive seals. These products are manufactured from advanced elastomers, thermoplastics, and metal-reinforced designs that withstand extreme temperatures, aggressive chemicals, high pressures, and surface speeds ranging from stationary to tens of meters per second. For design engineers specifying sealing solutions, maintenance teams replacing worn seals, and OEMs seeking to extend equipment service intervals, SKF seals represent the sealing technology partner that ensures bearing arrangements and mechanical systems perform reliably in their intended operating environments.

Complete Industrial & Automotive Seal Range
From heavy industrial radial shaft seals for mining equipment to precision automotive crankshaft seals, SKF manufactures sealing solutions for virtually every rotating shaft application.
SKF Wave Lip Technology Reduces Heat Generation
Patented lip geometry pumps lubricant back toward the oil side more effectively, reducing under-lip temperature and extending seal life compared to conventional lip designs.
Advanced Elastomer Materials for Application-Specific Performance
Select from nitrile rubber (NBR) for general applications, fluoroelastomer (FKM) for high temperatures and chemical resistance, and PTFE for extreme chemical and thermal conditions.
SKF Taconite Seals for Extreme Contamination
Designed for split housings in highly contaminated and wet applications, these heavy-duty seals virtually eliminate contaminant ingress in mining, steel, and cement environments.
Split Seal Designs for In-Situ Replacement
Avoid the downtime and disassembly required for solid seal replacement — split seals install around existing shafts, dramatically reducing maintenance time.
SKF Speedi-Sleeve Shaft Repair Solutions
Wear sleeve technology restores damaged shaft sealing surfaces to original specifications without shaft disassembly, machining, or replacement.
The Cost of Seal Failure: Why Quality Sealing Matters
Seal failure is one of the most common causes of premature bearing failure and unplanned machinery downtime. When a seal loses its ability to retain lubricant and exclude contamination, the bearing it protects degrades rapidly — contaminated lubricant becomes an abrasive slurry that accelerates wear, while lubricant loss leads to metal-to-metal contact and catastrophic failure. Studies have shown that contamination accounts for up to 14% of premature bearing failures, with inadequate or failed seals as the primary root cause. Investing in high-quality SKF seals with materials and lip geometries optimized for the specific operating conditions — temperature, speed, pressure, media, contamination type — pays dividends through extended bearing life, reduced lubricant consumption, fewer unplanned maintenance interventions, and greater production availability. The incremental cost of a premium seal is negligible compared to the total cost of a single unscheduled machine shutdown.
Seal Selection Factors: Temperature, Speed, Media & Pressure
Selecting the right seal requires systematic evaluation of the operating environment. Temperature determines the elastomer choice: standard NBR for -40°C to +100°C, FKM for -20°C to +200°C, and PTFE for extreme chemical and thermal conditions beyond 200°C. Shaft speed dictates lip design and material — high surface speeds require hydrodynamic lip features that manage heat generation. The sealed media (oil type, grease consistency, chemical composition) must be compatible with the seal material to prevent swelling, hardening, or chemical degradation. Pressure differentials across the seal influence whether a standard lip seal is sufficient or whether a reinforced design is required. SKF provides comprehensive seal selection guides, application data sheets, and engineering support to ensure the specified seal matches all operating conditions for maximum reliability.
