The SF-2 Boundary Self-Lubricating Oilless Sliding Bushing Bearing is a high-performance, maintenance-free bearing made from special composite materials. It features excellent wear resistance and self-lubricating properties. As a Lead-Free Boundary Bush, it meets environmental standards and is ideal for high-load, low-speed oscillating or rotating applications. It is widely used in automotive, construction machinery, agricultural equipment, and industrial automation.
- Self-Lubricating & Maintenance-Free – Embedded solid lubricants eliminate the need for external oiling, reducing maintenance costs in hard-to-reach environments.
- High Wear Resistance & Long Service Life – Made from high-strength composite materials with a low friction coefficient, ensuring durability and extended equipment lifespan.
- Eco-Friendly & Lead-Free Design – Complies with RoHS standards, making it safe for food, medical, and other sensitive industries.
- High Load Capacity – Optimized structural design supports heavy radial loads and impact forces, suitable for heavy-duty machinery.
- Low Noise & Smooth Operation – The self-lubricating layer minimizes metal-to-metal friction, reducing noise and improving operational stability.
