oil free bearing

Shop a large range of flanged bearing bushings – maintenance-free self-lubricating slide bearings with dry lubricating pins at bronzelube.com. Support all your metal copper bushing and maintenance repair needs … with excellent quality, to win customers of all ages.

Brief Description

This material provides a maintenance-free and low friction bearing solution, particularly for high load and intermittent oscillating motion. Solid lubricants within the bronze combine the strength of the bronze with the wear resistance of the graphite. Applications covered are automotive production lines, water industry, dam gates, plastic molding machinery etc. Different types of bronze alloy can be offered according to the application.

Oil-Free Bearing Machine Design, Self Lubricating – Self Lubricating Bearings

Over many Years Of Quality And Service. Work in High Temp & Submerged Applications Where Grease, Oil & Plastics Fail. Increased reliability. Hi-Temp Bearing Solution. Non-galling. Run dry & keep running.

Self-lubricating slide bearings are designed for applications where external lubrication is not possible (For example excavators).
The plugged graphite is compressed and molded into bearings to ensure that the product is maintenance-free. No auxiliary lubrication of any kind is required. At the start of the operation, a film of plugged graphite is transferred to the shaft. This is acceptable for some relatively demanding environments (lubricant contamination is prohibited).

Compared with standard traditional lubricated bronze oil-free bearings, self-lubricating bearings are also ideal for environments in a wider temperature range.

What are oil-free bearingsand how do they work?
Oil-free bearing is a self-lubricating bearing with both metal and lubricating properties. The metal substrate supports the load, and a specially formulated solid material such as graphite provides lubrication.

Oil-free bearings have the characteristics of high bearing capacity, impact resistance, high-temperature resistance, and strong self-lubrication ability.

Bronze Bearings, Bronze Material, Suppliers of bronze bearing material. Our aim is to create the greatest value for our customers.

oil-free bearing of special specifications is suitable for heavy load, low speed, reciprocating or swing, and other difficult to lubricate and form oil film, not afraid of washing and other acid occasions. Erosion and erosion of liquids. For example, some critical equipment of industrial and mining enterprises in mining environments operate under extremely harsh operating conditions. Because the equipment is heavy, the ambient temperature is high, the dust is large or the air contains acidic corrosive gases such as CO and SO2, which brings many problems to the lubrication of the equipment and serious friction and wear.
Optional oil-free bearing, with small friction coefficient, wear-resistance and corrosion resistance, oil-free self-lubrication, long service life and so on. Use it to reduce costs, reduce noise and prevent sticking and sliding.
Classification:
Metal base solid graphite plugged oil free bearing
Graphite and other composite solid lubricants are embedded in the metal matrix of high-performance solid lubrication products. The limitation of relying on oil film lubrication is broken through.
