General-Purpose Self-Lubricating Bearings

Material Overview:
This product is constructed with a high-quality low-carbon steel backing, an intermediate sintered porous bronze layer, and a surface layer featuring a rolled mixture of PTFE and lead (Pb). It offers excellent self-lubricating, wear-resistant, and low-friction properties, fully leveraging the combined advantages of metals and multi-element polymers. In various industrial applications, this product has widely replaced traditional ball bearings, needle roller bearings, and linear bearings.

Scope of Application:

1. To save costs on lubrication system design, maintenance, and repair, and to eliminate the hassle of periodic lubrication.
2. When bearing friction must be reduced to an absolute minimum.
3. When lubricant circulation is ineffective due to low-speed, heavy-load conditions, intermittent operations, or oscillating movements.
4. When plastic or other conventional bearings are inadequate due to excessive loads or the inability to maintain dimensional precision.
5. When operating under extreme temperatures, ranging from as low as -190°C to as high as +278°C.
6. For applications submerged in liquids such as water or chemicals, or in steam environments.
7. When the use of lubricants would cause contamination, or when other types of bearings are otherwise unsuitable.

Superior Performance Characteristics:

1. The bearing surface has extremely low static and dynamic coefficients of friction, ensuring smooth radial and axial sliding without lubrication and preventing the stick-slip phenomenon. It can also be used in lubricated environments.
2. Features a wide operating temperature range from -190°C to +278°C.
3. Highly suitable for heavy loads, shock loads, intermittent operations, and oscillating movements.
4. Anti-static properties. (The electrical resistance upon assembly is within the range of 1 to 9 ohms per cm² of contact area, preventing static electricity buildup).
5. The bearing surface offers excellent chemical resistance. It does not corrode when exposed to various industrial chemicals and gases, and remains unaffected by solvents such as petroleum and alcohol.
6. Does not damage or score the mating shaft surface.
7. Exceptionally long service life.
8. Lightweight and thin-walled (wall thickness of 1 to 3 mm), saving space and enabling highly compact and lightweight equipment designs.
9. Quiet and noise-free operation.
10. Completely maintenance-free (no lubrication required).
