SF-2 Boundary Self-Lubricating Bearing: High-Performance Lubrication Solution

Comparing with SF-1 Oilless Bearing & JF-800 Bi-metal Bearing

Self-lubricating bearings are critical in applications where traditional lubrication is impractical. Among the most widely used types are SF-1 Oilless Bearings, SF-2 Boundary Self-Lubricating Bearings, and JF-800 Bi-metal Bearings.

SF-2Y Boundary Self-lubricating Bearing

What is an SF-2 Boundary Self-Lubricating Bearing?

The SF-2 bearing is an advanced self-lubricating bearing with a steel-backed structure and a porous bronze sintered layer, impregnated with PTFE (Polytetrafluoroethylene) and lead mixtures. It provides excellent wear resistance and low friction under boundary lubrication conditions.

Key Features of SF-2 Bearings:
Material: Steel-backed bronze sintered layer with PTFE/lead coating
Self-Lubrication: Operates without external grease or oil
Load Capacity: Higher than SF-1, suitable for moderate to heavy loads
Speed Range: Suitable for low to medium-speed applications
Temperature Range: -40°C to +250°C
Applications: Automotive, industrial machinery, construction equipment

Comparison with SF-1 Oilless Bearing & JF-800 Bi-metal Bearing

Why Choose SF-2 Over SF-1 or JF-800?

Better than SF-1: Higher load capacity and temperature resistance.
More Self-Sufficient than JF-800: No need for external lubrication, reducing maintenance.
Cost-Effective: Balances performance and cost, making it ideal for medium-duty applications.

The SF-2 Boundary Self-Lubricating Bearing is an excellent choice for applications requiring reliable, maintenance-free operation under moderate loads and temperatures. While SF-1 is suitable for lighter loads and JF-800 excels in high-load scenarios, the SF-2 provides a balanced solution for industries seeking durability and efficiency.
