一、What is an oil-free bushing
Oil-free bushings are also known as oil-free bearings. This product is a self-lubricating bearing among sliding bearings.
It is a novel lubricating bearing that combines the characteristics of metal bearings and oil-free lubricating bearings. The metal bears the load, and the specially formulated solid lubricating material acts as lubrication, which results in strong load-bearing capacity, high temperature resistance, impact resistance, and self-lubricating capabilities. Strong characteristics.
It is especially suitable for heavy loads, low speeds, reciprocating or swinging situations where it is difficult to lubricate and form an oil film. It is also not afraid of corrosion and erosion by water flushing and other acids.
二、Characteristics of oil-free bushings
01. Low maintenance frequencies can be used for both linear motion and rotational motion
02. Can be used under harsh conditions of high and low temperatures
03. Compared with linear bearings, the bushing is thinner and saves space
04. Compared with ball-type linear bearings, oil-free bushings are suitable for low-speed and heavy-load applications
三、Classification of oil-free bushings
Composite bushing (SF-1/SF-2)
The steel plate layer plays the role of assembly positioning and bearing pressure; the copper powder layer plays the role of connecting plastics and auxiliary friction reduction;
Advantage: it can be self-lubricated even when there is no oil, it has low noise during operation, its thin-wall design structure is small, and its wear resistance can maintain long-term wear-free. It is a new type of bearing that replaces needle roller bearings, oil bearings and copper alloy bearings.
Bronze Bushing
Using a specially formulated high-density copper alloy strip as the base, the surface can be rolled with diamond-shaped or hemispherical oil holes and oil grooves according to user requirements.
Advantage: high density, large load-bearing pressure, good wear resistance, and long service life. It can replace the traditional cast copper sleeve, reduce the size of the machine, and reduce the cost. It can also be made into bearing bushes, flanged bushings, thrust washers and ball bowls.
Bimetal Bushing
The outer surface of the bearing is made of steel and the inner surface is sintered bronze alloy. The solid lubricant is evenly distributed in the alloy layer. When used in oily conditions, it can replace copper sleeves, babbitt alloy and roller bearings
Advantage: low cost, thin-walled design, small structure, good wear resistance and good lubricity. Various forms of oil grooves and oil holes are designed according to the lubrication conditions provided by customers, and it can be adapted to mass production.
Graphite Bushing
High-strength metal matrix embedded with solid lubricant. It has obvious advantages when used under high load-bearing and oil-free conditions. It can replace rolling bearings and copper alloy bearings in high-pressure, high-temperature and high-precision situations
Advantage: cost-effective, highly adaptable, wear-resistant, and has excellent axial and radial load capacity. JDB products can be used in environments that general copper sleeves cannot meet to solve special needs.
Solid Special Bronze Bushing
Based on copper alloy
Advantage: It can achieve micro operation and has excellent sintering resistance. It is suitable for low load and high speed operation and has better performance under oil and lubrication conditions
Steel Bushing
It can well avoid the lubrication blind area on the inner surface of the shaft sleeve, the hesitation axis is densely covered, and the oil storage is rich. It can effectively reduce the time between refueling.
Advantage: Has high pressure resistance. Wear-resistant and excellent lubrication properties, able to withstand axial force, corrosion-resistant, high transmission accuracy, more economical and affordable than copper alloy type, mostly used in medium-load and low-speed working conditions
