VSB-50 Solid Lubricating Bearings
Characteristics
with Solid Graphite Lubrication. Various material specifications,
standard and special shapes are also available
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℃
Strusture
VSB-50 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.

Typical applicaton
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.
