Base material properties
1. Can be used for a long time without maintenance;
2. Designed for high static and dynamic load;
3. It has very low and smooth friction factors, and no “sticking” phenomenon;
4. Dust resistance, corrosion resistance, impact resistance, and edge load resistance;
5. Metal base material has good shock absorption capacity;
6. Can be used in a wide temperature range;
7. Suitable for reciprocating, rotating and swinging, and other frequent start-up and difficult to form oil film occasions.

Material organization

JFB650 is based on high-strength copper alloys, which provide a high load-carrying capacity while solid lubricants form a low friction pair, with holes in the working face in proportion to service conditions. Under the condition of dry friction, we design a layer of pre-lubrication film on the guide bushing bearing surface to ensure that the solid lubricant can be transferred to the dual parts in the shortest time and form an effective solid lubrication film

 Metric Graphite Plugged Guide Bushing Typical applications

Metal self-lubricating guide bush bearings can be used in dry friction, high temperature, high pressure, corrosive environment, humidity, and occasions affected by chemicals, and are widely used in automobile production lines, water conservancy projects, reservoir gates, injection molding machines, continuous casting machines, metallurgical machinery, mining machinery, turbine generators, hydraulic generators, and other fields.

High-strength brass guide bushing bearings with embedded solid lubricant The Graphite plugged bronze bearings series are self-lubricating bushing bearings composed of high-strength brass alloy bases made with advanced casting technology and embedded solid lubricants, graphite + additives with lubrication oil.

Sourcing Copper Guide Bushing For Injectors from China Now. Self-lubricating bearing is used where the demand for maintenance-free operation, high load, or high temperature makes it impossible to use conventional bearings.  Manufactured and sell the bearing from China. Function oil-free bronze self-lubricating bearings use high-grade bronze alloys as their base material and have a finely finished surface with pockets in which a specially formulated solid lubricant is embedded. The pattern of the lubricating material is arranged geometrically, so that the entire bearing surface is lubricated permanently, in the direction of motion. During operation, a very thin, but nevertheless extremely strong, lubricating film is deposited automatically over the complete moving surface. This film remains intact at all times, even at standstill. The solid lubricant covers 25–30% of the sliding surface. Oil-free Guide Bushing For Injectors are primarily intended for intermittent duty.

6. Can be used in a wide range of temperatures, from - 40℃+ 300℃

Guide Bushing For Injectors & Bronze Bearing Design

The geometry, as well as the choice of material, is based on the specific application of the bearing. This means that each bearing is specially made to meet all load, environmental, and temperature requirements where it is to be used.

Base material produces a wide range of copper-based alloys, which are used as base material on Guide Bushing For Injectors. Data relating to four of those alloys are given in the table below. The capacity or carrying load is very much dependent on the choice of alloy, The selection of the base material will thus be based on the requirement of load-carrying capacity. Note that the temperature has an influence on the allowable load values and also the choice of lubricant.

Oilless Lubricating Guide Bushing For Injectors: The Self-Lubricating Effect –

Serviceable without the need for lubrication. Demonstrates high performance under high-load and low-speed operations. Demonstrates superior wear resistance in applications where oil film is seldom produced such as reciprocating motions, oscillation, frequent starts, and stops, etc. Superior chemical resistance and corrosion resistance. Standard products are available in various sizes. Applicable to rotation, oscillation, and reciprocating motion. Not for use underwater.

Installation self-lubricating bushing bearings require minimum or no maintenance provided they are correctly dimensioned and installed. Their high strength will then give a long bearing life. The following points are important when installing the bearing:

 Guide Bushing For Injectors is specially packed for transportation. Please do not remove the protective cover until installation.

 The sliding surface of the guide bushing bearing is treated with a solid lubricant coating.

This is applied to improve the running-in process.

Please make sure that this film is not damaged at the installation.

 Make sure the mating material is cleaned carefully. This is very important for the life of the oil-free guide bushing bearing.

The Guide Bushing For Injectors releases tiny amounts of solid lubricant during movement.
