Product Introduction

SF-2Y Self-Lubricating Bushings: High-Performance Dry Lubricant Bearings for Heavy Machinery

Discover the SF-2Y boundary self-lubricating bearing, an innovative solution designed to deliver exceptional performance in demanding industrial applications. These low friction bushings combine durability with maintenance-free operation, making them ideal for heavy machinery and equipment.

The SF-2Y self-lubricating bushing is engineered with a unique composite material that provides continuous lubrication without requiring external grease or oil. This dry lubricant bearing features a steel backing with a porous bronze interlayer and PTFE-based surface, creating an optimal balance between strength and low friction properties.

  • Maintenance-free operation - Eliminates the need for relubrication
  • Extended service life - Outperforms traditional bushings by 3-5 times
  • Reduced downtime - Withstands harsh conditions without performance degradation
  • Cost-effective solution - Lowers maintenance costs and increases equipment efficiency
  • Versatile compatibility - Works in both rotary and oscillating motions

These industrial machinery bushings are widely used in:

  • Construction equipment (excavators, loaders, cranes)
  • Agricultural machinery (harvesters, tractors)
  • Material handling systems (conveyors, lifts)
  • Automotive components (suspension systems, steering)
  • Hydraulic cylinders and pivot points
  • Mining equipment and off-road vehicles

Why Choose Our SF-2Y Bearings?

Our low friction dry lubricant bushings offer distinct advantages over conventional solutions:

  • Superior wear resistance - Special PTFE formulation reduces material wear
  • Corrosion protection - Ideal for wet or chemically aggressive environments
  • No stick-slip effect - Ensures smooth operation even at low speeds
  • Custom sizes available - We can manufacture to your specific dimensions
  • ISO 9001 certified - Consistent quality guaranteed

Installation Guidelines

For optimal performance of your SF-2Y boundary bearings:

  • Ensure proper clearance (0.1-0.3% of shaft diameter)
  • Clean mating surfaces thoroughly before installation
  • Press-fit using proper tools to avoid damage
  • Run-in period recommended for maximum efficiency
