Metallic Sliding bearings having been used widely.The Oiles VSB-50
series are self-lubricating bearings composed of highstrength brass
alloy bases made with advanced casting technology and embedded
solid lubricants. They may be combined with various types of solid
lubricants according to the conditions of use.
OILES Self-lubricating Bearings
Compared with normal plain bearings, TOP Bearings self-lubricating bearings are superior in wear resistance, seizure
resistance and friction properties, and realize performance
enhancement and maintenance-free.
Feature
■Usable in water
■ Demonstrates superior wear resistance in applications where oil
film is seldom produced such as reciprocating motions,
oscillation,frequent starts and stops, etc.
■ Superior chemical resistance and corrosion resistance.
■ Standard products are available.
■ Serviceable without the need for lubrication. Demonstrates high
performance under high-load and low-speed operations.

Characteristics
TOB-50W WASHER Thrust washers PAW
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
TOB-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.
