Oil-Free Bearings (Self-Lubricating Bearings)

In today’s high-performance mechanical and industrial systems, downtime and maintenance costs are critical factors. At Uni-Drive, we supply advanced oil-free bearing technologies designed to enhance reliability and reduce servicing requirements. These self-lubricating bearings — including metal-polymer composite, bronze, and bimetal types — feature built-in solid lubricants that eliminate the need for external oil or grease.

By operating without auxiliary lubrication, Uni-Drive Oil-Free Bearings offer superior advantages: reduced maintenance frequency, elimination of lubricant leakage or contamination, and stable performance even under high-temperature, dusty, or corrosive environments. The absence of oil systems simplifies machine design and prevents lubrication-related failures, contributing to longer service life and improved operational efficiency.

Range Available
Uni-Drive offers a comprehensive range of oil-free bearing products to suit diverse industrial and mechanical applications. Our lineup includes metal-polymer composite (PTFE-based) bearings for general machinery, wrapped bronze and bimetal bearings for higher load capacities, graphite-plugged bronze bearings for heavy-duty, high-temperature environments, and solid lubricant bushings for continuous, maintenance-free operation. Custom sizes, materials, and surface coatings can also be tailored to meet specific design and performance requirements.

From construction machinery, hydraulic and pneumatic systems, to cooling towers, HVAC equipment, and general industrial machinery, Uni-Drive provides oil-free bearing solutions that meet demanding load and motion requirements. These bearings are ideal for applications where continuous, maintenance-free operation is essential — supporting our mission to deliver reliable, efficient, and sustainable mechanical power transmission solutions.
