Sliding materials Oilles bushings 2000 Sintered Multi-Layer Bearings With Dispersed Solid Lubricant
The 2000 sintered multi-layer oilless bushes with dispersed solid lubricant are innovative components designed to provide exceptional wear resistance and durability in a wide range of industrial applications. These bushes are manufactured using a sintering process, which involves compressing and heating powdered metal materials to create a solid, porous structure.
The multi-layer design of these bushes allows for superior performance under high loads and speeds. Each layer is carefully crafted to optimize strength, stiffness, and lubrication properties. The dispersed solid lubricant within the material ensures smooth operation without the need for regular oiling or lubrication, significantly reducing maintenance requirements.
The sintered construction of these bushes also provides excellent heat resistance and corrosion resistance, ensuring reliable performance even in harsh environments. This makes them suitable for use in various machinery and equipment, including pumps, motors, and gearboxes.
The 2000 sintered multi-layer oilless bushes with dispersed solid lubricant offer a cost-effective and long-lasting solution for industrial applications that require high-performance bushings. Their unique design and material properties ensure smooth and efficient operation, reducing downtime and extending the lifespan of machinery and equipment.

Oilles 2000 bushing sleeve are Sintered Multi-Layer Bearings bushing sleeve made up of sliding surfaces made of special sintered material and steel back metals. The solid lubricant made mainly of graphite is dispersed in the sintered layer, which is sintered and impregnated with oil.
Self-lubricating , Maintenance-free Bushing sleeve
Oilles 2000 bushing sleeve is a Sintered Multi-Layer Bearings bushing sleeve made of a special sintered material which forms the sliding surface and the steel material forms the support.
The sintered layers are of a special copper-nickel alloy containing a uniformly dispersed lubricating solid, the main component of which is graphite. Solid lubricants will be released onto the Sintered Multi-Layer Bearings bushing sleeve surface when wear occurs. This ensures a lower friction coefficient during operation.
In addition, these sintered layers are impregnated with oil. Applications covered include wear plates for automotive tools, industrial robots, wear plates for plastic injection molding machines and link Sintered Multi-Layer Bearings bushing sleeve, construction machinery, etc.
Feature
· Dispersed solid lubricant allows motions in any direction and offers superior performance for minute movements.
· Serviceable without the need for lubrication.
· Features superior load resistance, speed characteristics, and wear resistance.
· Standard Oilles 2000 bushing sleeve products and plates for additional machining are available in various sizes.
· Shows many superior performances due to the effect of the oil retention force of the sintered copper alloy layer and the solid lubricant when lubricating oil is used tog.
· Thin bearing bushing sleeve enables compact design.
· Electrically conductive.
Characteristics
· Good wear and friction characteristics over a wide range of loads, speeds and temperatures without oil
· Also work well with grease
·Maintenance free, long life

Oil Impregnation Method
If the Bronze Bushing 2000 material is purchased and used by finishing it, it should be oil-impregnated after machining and then assembled in the housing. When the bushing sleeve Sintered Multi-Layer Bearings is stored for long or washed, it should be oil-impregnated again and then assembled in the housing. For the method, see the description about the oil impregnation method shown on page 250. Dip the machined bushing sleeveSintered Multi-Layer Bearings in lubricating oil for 24 hours or more before using it, if oil impregnation (by heating) is disabled.
