Engineered for high-performance applications, PTFE-based plain bearings with stainless steel backing combine the self-lubricating, low-friction properties of PTFE with the strength and durability of stainless steel. These bearings are designed to deliver smooth, reliable motion even under heavy loads, extreme temperatures, and harsh environments.
Low-Friction PTFE Surface: Ensures effortless movement and reduces wear on mating components.
Stainless Steel Backing: Provides superior strength, dimensional stability, and resistance to corrosion.
Maintenance-Free Operation: Self-lubricating PTFE eliminates the need for frequent greasing.
High Load & Temperature Capacity: Suitable for demanding industrial, automotive, and marine applications.
Reliable Performance in Harsh Conditions: Withstands moisture, chemicals, and temperature fluctuations without compromising durability.
Perfect for sliding, pivoting, and rotational applications, PTFE-based stainless steel-backed bearings combine longevity, smooth operation, and robust resistance to corrosion, making them an ideal choice for critical mechanical systems.
