Performance characteristics and applicable scenarios SKF’s plain bearings (including bushings, thrust washers and strips) The performance of SKF’s plain bearings (including bushings, thrust washers and strips) mainly depends on factors such as load, lubrication, surface roughness, sliding speed and operating temperature. The interaction of these factors in a specific application enables SKF to provide products that can adapt to various working conditions. For example, SKF’s plain bearings excel in low friction, wear resistance and corrosion resistance, and are suitable for applications that require high precision and long life. ‌

Design and material selection SKF’s plain bearings have a significant impact on their performance. For example, SKF’s polymer cages have the characteristics of low weight, low noise, good sliding performance and low friction, which are suitable for applications that need to reduce wear and noise.

In addition, SKF also provides various types of bushings and thrust washers to meet different load requirements and working environments.

SKF Bushings, Thrust Washers, and Strips are precision-engineered components designed to reduce friction, manage axial/radial loads, and enhance the longevity of rotating machinery. These accessories play a critical role in applications where traditional bearings are impractical or where additional support is required. SKF’s expertise in material science and manufacturing ensures these components deliver exceptional durability, alignment, and performance across industries such as automotive, aerospace, heavy machinery, and renewable energy.

Key Features & Benefits of ‌SKF’s bushings, thrust washers and strips

  1. SKF Bushings (Plain Bearings)

Low-Friction Operation: Made from self-lubricating materials (e.g., bronze, PTFE composites) or steel-backed polymers, bushings reduce wear in oscillating or sliding applications.

High Load Capacity: Engineered to handle radial and axial loads in harsh environments, such as hydraulic cylinders or suspension systems.

Corrosion Resistance: Stainless steel or coated variants withstand moisture, chemicals, and extreme temperatures.

Custom Designs: Available in cylindrical, flanged, or spherical shapes to fit unique housing requirements.

  1. SKF Thrust Washers

Axial Load Management: Precision-ground washers distribute thrust loads evenly, preventing metal-to-metal contact in gearboxes, pumps, and transmissions.

Material Versatility: Options include bronze, steel, or polymer composites for applications ranging from high-speed machinery to food processing.

Surface Treatments: Phosphate, zinc, or Durotect® coatings enhance wear resistance and reduce friction.

Thermal Stability: Operate reliably in temperatures from -50°C to +300°C (varies by material).

  1. SKF Strips (Shim Stock & Wear Strips)

Alignment & Spacing: Precision-thickness strips (0.05 mm to 3 mm) adjust clearances in assemblies like engine blocks or turbine housings.

Wear Protection: Hardened steel or composite strips protect surfaces from abrasion in conveyor systems or industrial guides.

Easy Fabrication: Can be cut, bent, or drilled on-site for custom repairs or retrofits.

SKF Bushings, Thrust Washers, and Strips are essential for optimizing machinery performance, reducing downtime, and extending equipment lifespan across industries. By combining precision engineering, advanced materials, and customizable designs, these components address the challenges of friction, alignment, and load management in even the most demanding environments. Whether used in automotive drivetrains, wind turbines, or aerospace actuators, SKF’s accessories deliver unmatched reliability, efficiency, and cost savings. Backed by SKF’s global network and commitment to innovation, they represent a strategic investment in operational excellence and sustainability.
