OilLess Bushes, Bush Bearings & Wear Plates

The Self-Lubricating OilLess Bus Graphite Embedded type Equi-si Equi-spaced holes are drilled all over the walls to cover approximately 25% of the total surface area, and are then plugged with graphite rods acting as solid lubricant which is constantly available for lubrication during the life time of the Bush. These are broadly categorised into three groups as per their Base Materiay

1. OilLess Grade JA#500 [Copper Based Alloy as Base M]

2. OilLess Grade UB#1000 [Ultra Bronze as Base Base M]>

3. OilLess Grade JA#2000 [Steel Based Alloy as Base M]

1. OilLess Grade JA#500<> The Grade “JA#500”, is a material where in a special high tensile strength copper based alloy is used as the base material. In this base material are inserts of a solid lubricant – GRAPHITE, These components can be used where operating temperatures are high and where corrosion resistance is required. They are similar to 500SP of Japan, Lubo 500 of US etc, etc.

2. OilLess Grade UB#10 ULTRA BRONZE Graphite Embedded Bushes are recommended for use in areas where lubrication is a problem but operating temperatures are @75 °C. The general physical & mechanical properties of these Bushes are similar to ULTRA BRONZE and they have @20-25% solid Graphite in them. These Bushes are branded as Grade “UB#1000”. They are not recommended for application in water.

3. OilLess Grade JA#2000: The Grade “JA#2000”, is a material where in a special high tensile Steel based alloy is used as the base material. In this base material are inserts of a solid lubricant – GRAPHITE, These components can be used where operating temperatures are ve @400 °C.
