Description
TOB-50 FlangeSolid Bronze Metallic Self-lubricating Bearings
Copper Cast Bronze Bearings / Flanged Bronze Bearings / Cast Bronze Bearing with Graphite Plugs
Characteristics
TOB-50 Flange
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-50 Flange 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.
