Gasket cast bronze graphite plugged bronze bushings, also known as oilless bearings, are a type of self-lubricating bearing system that utilizes the unique properties of graphite and bronze to provide superior wear resistance and durability.

These bushings are cast from bronze alloy, often C86300, which is a high-tin bronze alloy that offers excellent corrosion resistance and mechanical strength. The graphite plugs or inserts within the bushings provide a continuous lubricating film between the moving surfaces, eliminating the need for external lubrication.

The gasket design of these bushings allows for easy installation and replacement, while also providing a seal against contaminants and moisture. This ensures that the bearings remain in optimal condition, even in harsh environments.

Graphite plugged bronze bushings are commonly used in a wide range of applications, including robotics, heavy machinery, and industrial equipment. They are ideal for applications where lubrication is difficult or undesirable, as well as for applications that require long-term reliability and durability.

In summary, gasket cast bronze graphite plugged bronze bushings, or oilless bearings, offer a self-lubricating bearing solution that provides superior wear resistance, durability, and ease of installation and maintenance.

VIIPLUS China manufactures self lube wear plates that conform to all industry standards ( manganese bronze,tin bronze,high strength brass or aluminum bronze, either with or without self-lubricating graphite.

Copper Bronze alloy inlaying solid self-lubricating bearing lubrication, combined with copper alloy wear resistance and self-lubricating properties of solid lubricants, in the use process without refueling maintenance.

Products are widely used in high load, swing or intermittent movement, such as vehicle production lines, water turbine, reservoir work/accident door, plastic machinery, etc. According to the using condition, VIIPLUS can provide various types of copper alloy.

Oilless bearings have been developed for high load, low speed applications and are made of rotational cast high-strength bronze using a specially formed graphite plug as lubricant.

Plain Bearings bearings have been developed for high load, low speed applications and are made of rotational cast high-strength bronze using a specially formed graphite plug as lubricant.

Our VIIPLUS plain bearings are available in metric and imperial sizes from stock. Our in-house machining service is able to produce non-standard sizes to suit specific customer requirements.

VIIPLUS range of oilless bearings are the perfect solution for projects where lubrication cannot easily be provided or where conventional lubricants may carbonise. The design of oil feeding systems is time consuming and expensive

- The use of our oilless bearings can greatly reduce costs of maintenance and oil as it removes any need for such a system.

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-50W WASHER 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.
