Technical information and standard dimensions on the datasheet
Self-Lubricating L-Gibs are used to make custom cams and slides. These L-Gibs are made of aluminum bronze and contain graphite plugs. The graphite plugs eliminate the need for grease which makes these L-Gibs perfect for medical, food grade or high speed applications.
Properties: “L-Gibs – Solid Bronze – Self-Lubricating Bronze Plate, L-shaped bronze plates “
How It Works ?
When the mutual friction occurs between two non-lubricated surfaces, the two contacts with the uneven surface of the peak by the shear, stick-slip
and plastic deformation giving rise to friction and wear. Conventional lubricants can significantly reduce these effects, however, the conventional
lubricant will be more and more squeezed out of the contact area with increasing surface which formed the dry friction or boundary lubrication.
With slide guide, the lubrication is effected by the sliding material itself, The solid lubricant is released from the friction
material by micro-movement. This gives the sliding partners smooth surfaces with a firmly adhesive solid lubricant film, the solid lubricant film
remains within the contact area even under heavy loads. The embedded solid lubricant plugs can be continuously provided to the friction surface
to reduce friction resistance and wear, thus make the bearing can be worked under low wear rate and long-life service.
How to use graphite copper sleeve bearing
Graphite copper set of works: general solid lubricant accounts for 20-30% of the friction surface, graphite and copper set of self-lubricating bearing lubrication principle is in the process of sliding friction of shaft and bearing, part of the graphite particles move to the shaft and the bearing friction on the surface, forming a layer of a copper alloy bushing stable solid lubricant membrane, prevent the shaft and bearing directly adhesive wear.
This kind of reasonable die guide sleeve combines the advantages of metal alloy and nonmetal anti-friction material and makes them complementary, that is, graphite inlaid lubricating bearing has a high bearing capacity of metal, and obtains the lubricating property of anti-friction material. Therefore, it is especially suitable for non-refueling, less refueling, high temperature, high load or water environment. Graphite copper sleeve, also known as self-lubricating bearing, is in the copper sleeve as a metal matrix friction surface developed arranged in order, the appropriate size of holes, and embedded graphite or molybdenum disulfide as a solid lubricant product with self-lubricating properties. At present, graphite copper cover has been widely used in engineering machinery, metallurgical machinery, mining machinery, locomotive support, steel rolling equipment, ship machinery, mold equipment, textile machinery, gas turbine, and another low-speed heavy load, high-speed light load, and other occasions.
