The Double Loop Oil Grooved Cast Bronze Bushings, featuring self-lubricating and corrosion resistance properties, are designed for applications that require high performance and durability. These bushings are made from cast bronze, a material known for its excellent wear resistance and load-bearing capacity.
The key feature of these bushings is the double loop oil grooving design. This design allows for even distribution of lubricating oil within the bushing, ensuring constant lubrication and reducing the chances of friction and wear. The self-lubricating nature of the bushings further enhances their durability and performance, reducing the need for regular maintenance and replacement.
In addition to their self-lubricating properties, these bushings also exhibit excellent corrosion resistance. This is due to the bronze material, which is resistant to many chemicals and environments that can cause corrosion. This corrosion resistance makes the bushings suitable for use in a wide range of applications, including those with harsh or corrosive environments.
Overall, the Double Loop Oil Grooved Cast Bronze Bushings with self-lubricating and corrosion resistance properties are an excellent choice for applications that require high performance, durability, and reliability. Their unique design and material composition ensure consistent and efficient operation, reducing downtime and maintenance costs.
Any of our standard stock sizes for bronze sleeve bearings are adaptable to graphite. There are several styles of graphite available, however, we specialize in custom cutting! Graphite is mechanically forced into the groove under extreme pressure. A film of lubricant is transferred to the shaft when it starts to turn.
We are specialists in cutting lubrication grooves bronze bushings or with oil holes .Examples include Double Loop Groove and Single Loop Groove. In addition to our standard groove options we also offer grooves filled with graphite.Other common groove patterns available are Circular, straight Figure 8,double Figure 8.Any of these grooves can be contained within the length of the part or breaking out the ends. Call us for assistance in determining which pattern is most appropriate for your application. There are industry standard groove patterns that are available for different applications.
Standard size graphite plugged sleeve bushings are available for purchase online at www.bronzegleitlager.com.
Hundreds of industry standard size sleeve bushings are listed in both inch and metric standard sizes. These products are inventoried for quick shipment.
Grooved Cast Bronze BushingsThese plain bearings are most suitable for applications involving a high loading and requiring maintenance-free operation.The oil groove should not break out the end of the bushing.

Groove copper sleeve is a kind of high - force brass bearing lubricated with groove barrel oil.This product has the traditional tin bronze bearing function, because USES the high profit brass, its hardness has raised one time, therefore USES this product in the low speed occasion, may lengthen the general bronze sleeve life one time, moreover its load bearing pressure is big, can adapt the heavy load occasion use.At present, the product is mainly used for excavator stress joint parts and large gearbox.
Copper alloy graphite groove solid lubricated bearing is a kind of high wear resistant solid lubricated bearing, which is based on aluminum brass and is processed into ring groove with the same spacing on the inner diameter of the bearing.In the process of use, due to the role of friction heat, the solid lubrication material in the aluminum brass groove on the inner diameter surface will produce micro expansion, so as to generate friction with the shaft first and form a transfer film on the shaft, so as to reduce the friction coefficient, reduce the wear of the shaft and shaft sleeve, extend the service life and other effects.The product is especially suitable for precision mold guide sleeve, precision guide rail and other reciprocating linear motion conditions.
We are specialists in cutting lubrication grooves in virtually any pattern. Groove. Other common groove patterns available are figure eight, double figure eight, loop, double loop, circular, wick or straight. Any of these grooves can be contained within the length of the part or breaking out the ends. Call us for assistance in determining which pattern is most appropriate for your application. There are industry standard groove patterns that are available for different applications.

VSB-50 Flange
1. May work without any ol for long period
2. Extremely high load capacity, good anti-wear and lower friction
3. Particularly appropriate for low speed and high load
4. Suitable for reciprocating, oscillation or intermittent motion where oil film is hard to be formed
5. Good chemical resistant and anti-corrosion characteristics
6. Can b€ used in wide range of temperature from -40℃-+300℃
VSB-50 Flange material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal withstands high load and the solid lubricants provide self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.
