L Shape Oilless Wear Plate Centrifugal Casting Self-Lubricating High Load is through the solid lubricant embedded in the appropriate position of the workpiece.
Wear plates are crucial components in industrial equipment that protect surfaces from excessive wear and damage caused by friction, impact, or other forms of abrasion. An L-shaped oilless wear plate is a specialized type of wear plate that is designed to operate without lubrication, making it ideal for use in applications where oil or grease may not be practical or safe.
L-shaped oilless wear plate consists of highly wear-resistance copper cast alloy whose sliding surfaces are evenly provided with a certain percentage of solid lubricant plugs according to work condition, high-strength copper alloy provides a high load-bearing capacity, and the solid lubricant can be the formation of low friction film.
Under technical dry running conditions, the bearing surface is designed with a thick running-in film which enables the solid lubricant to be transferred to the counter material at the first contact.
Bronze Oil-Free Slide Plates Suitable for low load position, wear performance worsens greatly when under middle or high load Can be applied in furnace door linage, furnace, conveyor, tool machines, light industries, etc.
Graphite Plug Plates
The bronze plate is manufactured with machined holes and/or grooves into which graphite is inserted. These graphite plugs act as the lubricant between the shaft and the plate. The graphite inserts provide a slippery coating that acts as ongoing, reliable lubrication between the surfaces.
This type of plate is often referred to in the market as SelfLube, plugged graphite, graphited, or simply self-lubricating.

Features:
Oilless wear plate uses high-strength brass or tin bronze as the base and is inlaid with solid lubricants according to different movement methods. It can be used for a long time under oil-free lubrication conditions or in water. Working under lubricated conditions, it is more suitable for heavy loads and low-speed conditions, where reciprocating, rotating, oscillating, and intermittent motions are difficult to form oil films. It has good wear resistance and an extremely low friction coefficient and has corrosion resistance and chemical resistance. sex. Currently mainly used in water conservancy machinery, dam working door hinge bearings, turbine bushings, iron, and steel industry, metallurgical equipment, rolling mills, continuous casting conveyor rollers, high-temperature blast furnaces, shaft bushings for drying furnaces, steam and locomotive industries, construction machinery, etc. Corrosion-resistant, water-lubricated occasions, high temperature, heavy-duty, medium-speed, and unrefutable working conditions, etc. The self-lubricating block combines the wear resistance of copper alloys and the self-lubricating properties of solid lubricants so that it does not require oil and maintenance during use. Various types of copper alloys are available.
