Split half bronze bearing bush  – extend your machine life

Copper-based self-lubricating bronze bush Inlaid solid lubricant bearing or shaft tile, widely used in metallurgical equipment, mining machinery, chemical equipment, heavy machinery, lifting and transportation machinery, bridges, water conservancy machinery video machinery in various fields.
The split bronze graphite bushings characteristics
1. In the process of using the half-bronze bearings, can be done without lubrication.
2. excellent friction reduction performance under high load to low-speed conditions.
3. in reciprocating motion, intermittent motion, oscillation difficult-to-form oil film conditions, and good wear resistance.
4. It can be used in water or medicinal solution.
5. Can be used under high-temperature conditions.
6. No limitation on size and shape.
The split bronze half-bearing bush can be processed according to the customer’s drawing, according to the standard, to arrange the oil tank.

Maintenance-free & high performance

Split self-lubricating bronze bearing is generally composed of two semicircles with axial split, the type of semicircles are straight sleeve, flange straight sleeve, double flange straight sleeve, etc. The graphite-based solid lubricant is inlaid on the shaft tile as a self-lubricating medium, no need to add oil when working (it is recommended to add oil when installing). In the work, the solid lubricant inlaid in the shaft tile is slowly released and evenly distributed on the surface of the coupling, forming a solid lubricating film, isolating the direct contact between the shaft and the sleeve base material, to reduce wear and extend the life of the equipment.
It breaks through the limitation of general bearing relying on oil film lubrication. In the process of use, through the friction heat to make solid lubrication and shaft friction, the formation of oil, and powder coexist lubrication excellent conditions, both to protect the shaft from wear, but also make solid lubrication characteristics eternal. Its hardness is twice as high as general copper bushings, and its performance is also twice as high.
At present, this split bronze bush has been used in a metallurgical continuous casting machine, train support, rolling equipment, mining machinery, ships, gas turbines, and other high-temperature, high-load, low-speed heavy load, and other occasions.
