High-strength brass bearings with embedded solid lubricant Oiles 500SP1-SL4 Bushings SPBL

TOP Bearings manufacture Thrust washers are annular plates or two semi-annular plates commonly used with radial sliding bearings for axial loading.

# 500 SP SL-4 Bush OILES Straight Type & Oiles #500SP Flange Bushing (SPF) | Oiles Bushings

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.
