KSOB-10WC Oil-Free Lubricated Gasket

SF-1W Oil-Free Lubricated Gasket

--A three-layer composite structure, the ultimate solution for axial maintenance-free

Definition

SF-1 adopts a three-layer composite structure: steel back + copper powder layer + PTFE lubrication layer. The steel back provides high strength support and good thermal conductivity. The sintered copper powder layer serves as the connection framework and assists in heat dissipation. The PTFE composite lubrication layer forms a transfer film during friction, achieving permanent self-lubrication without the need for any external oiling.
This structure combines the high load-bearing capacity of metals with the low friction characteristics of PTFE, with a friction coefficient as low as 0.04 to 0.10. It is widely used in fields such as automobiles, construction machinery, food machinery, and household appliances, and is an ideal alternative to traditional oil-filled bearings.

✅ Core Advantages
🔹 Three-layer composite structure
Using high-quality carbon steel as the base material, a sintered spherical bronze powder layer is placed in the middle, and a PTFE composite lubrication layer is covered on the surface. The steel back provides high strength support and good thermal conductivity, the bronze layer enhances the bonding force and assists in heat dissipation, and the PTFE layer forms a transfer film during friction, achieving lifelong self-lubrication.
🔹 Lifetime Lubrication-Free
No need for any external grease, completely eliminating oil contamination, and reducing maintenance costs. The friction coefficient is as low as 0.04 to 0.10, with the starting friction and running friction being similar, eliminating the "stick-slip" phenomenon.
🔹 High Load Capacity
Static load ≥ 250MPa, dynamic load ≥ 140MPa, meeting the requirements of heavy-duty axial support. Excellent impact resistance and fatigue resistance, suitable for frequent start-stop conditions.
🔹 Wide Temperature Range Adaptability
-50℃ ~ +250℃ stable operation, short-term temperature resistance up to 280℃, suitable for alternating cold and hot environments.
🔹 Strong Corrosion Resistance
PTFE layer resists acid, alkali, and solvent erosion, the stainless steel version passes a 500-hour salt spray test.
