The bronze bushing is to open cavities of appropriate size and orderly arrangement on the metal friction surface of the bearing matrix, and then embed a molded solid lubricant with unique self-lubricating properties in the cavities (the solid lubricant area is generally 25% of the friction area -35%) and made of self-lubricating bearings.The bearing combines the respective advantages of the metal matrix and the specially formulated lubricating material, breaking through the limitation of general bearings that rely on oil film lubrication.
The basic body of the sliding bearing should be determined according to the working conditions of the bearing itself. The more commonly used materials are high-strength brass, tin bronze, castings, etc. There are two main types of embedded solid lubricating materials, one is natural black lead, artificial graphite, and MoS2 synthesis, and the other is synthesized with PTFE as the matrix. According to the bearing's own operating conditions, the combination of different metal substrates and embedded solid lubricants can ensure that the product can meet the special needs of various temperature, load, motion and media operating conditions, while ensuring stable and reliable operation.

Tin bronze alloys are typically found in gear, high-strength bushing and bearing applications where high strength and low speeds and heavy loads are present. Other high-strength applications for these alloys are pump impellers, piston rings,
steam fittings and valve bodies. Tin bronze castings are utilized
in movable bridge components, turntables for bridges and other
structures for fixed and expansion bearings with slow or
intermittent movement with heavy loads.

Structure Characteristics and Applications
VSB-50 Solid Lubricating Bearing is produced by strengthening brass
that has good physical performance and good capability for casting. What's more, the brass material has pretty good anti-erosion abitity in air, fresh water and sea water. The surface is
regularly and finely machined with sockets in which particular
solid lubricant is filled. The product is widely used on
consecutive casting and rolling machines, mine-exploiting
equipments, ships, steam engine, etc.
VSB-50 Solid lubricating bearings
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 Solid Lubricant Sliding Bearings 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.
