Graphite Bearing

Bearings are divided into rolling bearings and sliding bearings, and graphite bearings are mostly used for sliding bearings. It is used in the bearings of conveyors, dryers, textile machines, submersible pump motors and other industrial sectors in food, beverage, textile, chemical and other industrial sectors. Such parts will inevitably cause pollution if grease lubricants are used, and the self-lubricating properties of graphite bearings are very high. Strong, corrosion-resistant, long-term operation without lubricating oil.

  • 产品介绍

Bearings are a kind of sliding parts commonly used in the machinery industry, and the materials are different from metal, non-metal and composite materials. Graphite bearing is a carbon bearing developed and developed on the basis of metal bearing according to the performance requirements of mechanical equipment, with graphite material as the main base material. Graphite bearings have different characteristics from metal bearings, mainly in: self-lubricating, high temperature resistance, corrosion resistance, light weight, etc.

Strong, corrosion-resistant, long-term operation without lubricating oil.

Graphite bearing lubricants are generally solid lubricants, which are synthesized from a variety of substances with good lubricating properties, and are embedded in the bearings and sliders to play a self-lubricating role. Under certain specific conditions, it can replace traditional lubricants to achieve good self-lubricating effect.

The main products of Henan Liugong include graphite thermal field, graphite mold, graphite sheet for lightning arrester, graphite crucible, graphite plate, isostatic graphite, high-purity graphite, EDM graphite, graphite sheet for SPD, graphite powder, graphite bearing, Graphite rings, graphite screws, various graphite special-shaped parts, etc. Products are now widely used in EDM, mold, solar photovoltaic, electronic semiconductor, metallurgy, chemical, industrial and quartz industries.

Liugong graphite bearings are made of isostatically-pressed high-purity graphite, and isostatically-pressed graphite is pressed from high-purity graphite.

Wear of graphite bearings:

The wear of carbon-graphite bearings depends on its material, shaft material and surface condition, total pressure, speed and surrounding environment. As far as bearings are concerned, there are two forms of friction, static friction and kinetic friction. Static friction depends on the surface state and the material used. Generally speaking, the static friction of carbon-graphite bearings is lower than that of metal bearings under the same conditions.

Application range of carbon-graphite bearings:

  1. It is used in places where the use of grease lubricants is not allowed when the bearing is running.

For example, bearings used in conveyors used in food, beverage, textile, chemical and other industrial sectors, dryers in the paper industry, cloth dryers in the textile industry, rayon looms, cigarette manufacturing equipment, and submersible pumps. In these places, the use of grease lubricants is prohibited, and the self-lubricating properties of carbon-graphite bearings are very strong, which can be used for dry running without the use of lubricating oil, so they can be widely used in these departments.

  1. Used in places where ordinary bearings cannot be used due to high temperature

Carbon-graphite bearings can be used in the bearings of ingot conveyors, boiler preheaters and flame tube ventilation doors and blowers in boiler rooms, high temperature furnace feeders, feeders in the iron and steel industry, and flue valve regulators, etc. to ensure its normal operation.

  1. Used in chemical and textile industries

Some bearings operate in corrosive gases or liquids. In this case, not only the use of grease lubricants is prohibited, but also the metal bearings will be corroded quickly. For example, centrifugal pumps whose impeller bearings are immersed in various liquids; fuel metering pumps whose bearings operate in liquids such as gasoline, paraffin, and kerosene; central heat circulation pumps whose main impeller bearings are immersed in hot water; Mixers in various corrosive media; automatic washing machines in which the main impeller bearings are immersed in hot water; liquid gauges in which the bearings are immersed in various liquids, and rayon wet processes with acid splashes Textile machines, etc., all use carbon-graphite bearings. In addition, modern technology also requires carbon-graphite bearings that can be used in complex environments with radioactive media.
