OOB-50 Self-lubricating bearings, solid bearings, copper-based bearings, boring machine bearing, earthmoving machinery bearings, bulldozer bearing, oilless bearing for food machinery
Solid bronze bearing is a kind of cast bearing, it's also called solid metal bearing, guide bush, solid sliding bearing, graphite plugged oilless bearing, graphite filled bushing, solid lubricant bearing, brass bushing and cooper bearing. Standard cylindrical bearing, flanged bearing, wear plate are available.
OOB-50 graphite plugged brass bushing is a type of solid metal bearing. This type of self-lubricating bearing is also called oilless bearing, brass bearing, cooper bushing, solid sliding bearing, guide bushing and graphite filled bearing.
The self-lubricating bearings are based on high-strength copper alloy where a certain proportion of solid lubricants are regularly arranged in accordance with working conditions. This kind of copper-based bearing combines the high abrasion resistance and high carrying capacity of copper alloy with the self-lubricating property of solid lubricants. This will result in significant reduction of maintenance cost of equipment.
1. The self-lubricating bearings can be used for a long time without maintenance.
2. It is designed for use under ultra high static load and dynamic load.
3. This product features extremely low and stable coefficient of friction. The phenomenon of adhesion never occurs.
4. Strong resistance to dust, corrosion, impact, and edge load
5. Metal substrate has superb shock-absorbing capacity.
6. This kind of solid bearing can be used within a very wide temperature range.
7. It is suitable for those with hardly formable oil films and various frequent starts such as reciprocation, rotation, swing, etc.
8. Extremely low wear rate and long service life
Usage
The self-lubricating bearings are applicable to the injection molding machines, automotive moulds, engineering machinery, hydraulic cylinders, large gearbox, metallurgical continuous casting machines, steel rolling equipment, mining machinery, ships, gas turbines, crane support, food machinery, and the water turbines, etc.
The solid lubricated brass bearing is primarily composed of high-strength special brass with HB ＞235. Its wear-resistant surface has a certain proportion of drilled holes. This kind of oil-free brass bearing is inset with a solid lubricant. Both its strength and hardness are higher than those of the sliding bearings.
Characteristics
1. Owing to higher mechanical strength and hardness, the solid lubricated brass bearing is provided with increased carrying capacity and abrasion resistance in comparison with it.
2. It can be applied in different industries such as mining machinery and engineering machinery.
3. The engineering machine bearing gives superb wear resistance under conditions of low speed and heavy load.
4. It is not suitable for use in seawater environment.
Special suitable for low loads and middle velocity operations, also perform well at high temperature
Excellent resistance to chemical attack and corrosion
Maintenance free
