What is an oil-free bushing
Oil-free bushings, also known as oil-free bearings, are self-lubricating bearings in sliding bearings.
It is a novel lubricated bearing that has the characteristics of both metal bearing and oil-free lubrication bearingThe metal bears the load, and the specially formulated solid lubricating material plays a lubricating role, which makes the bearing capacity strong, high temperature resistance, impact resistance, and strong self-lubrication ability.
It is especially suitable for heavy load, low speed, reciprocating or swinging and other occasions that are difficult to lubricate and form oil films, and are not afraid of water flushing and other acid erosion and erosion.
Oil-free bushing features
Low maintenance frequency, can be used for both linear and rotary motion.
It can also be used under harsh conditions of high and low temperatures.
Compared to linear bearings, the bushing thickness is thin and space-saving.
Compared to ball-type linear bearings, oil-free bushings are suitable for low-speed and heavy-duty applications.
Classification of oil-free bushings
Copper alloy type oil-free bushing
Features::
It is a popular product type due to its excellent wear resistance, excellent ability to withstand axial and radial loads, and high-precision linear and rotary movements.
Bronze casting oil-free bushing
Features::
It can realize small operation, excellent sintering resistance, and is suitable for low-load, high-speed operation, and excellent performance under the conditions of lubrication.
Oil-free bushing for composite layer
Features::
Thin-walled and compact structure, suitable for heavy-load, low-speed operation, low production cost, fast production speed, suitable for high precision requirements, but large batch requirements for working conditions.
Polyacetal resin type oil-free bushing
Features::
Polyacetal resin material, high stiffness and good wear resistance. Used in the food industry. It can effectively block dust intrusion, low operating noise, mostly used in low load, low speed working conditions, low production and manufacturing cost, large one-time production batch, suitable for occasions with large demand and low precision requirements.
Cast iron type oil-free bushing
Features::
It can withstand axial force, corrosion resistance, high conduction accuracy, and is more economical than copper alloy type, and is mostly used in medium load and low speed working conditions.
Aluminum-plastic plain linear bearings
Features::
Plastic plain bearing products, light weight and corrosion resistance. It can replace rolling linear bearings, and has the functions of heavy-duty, self-lubricating and low-noise use.
Oil-free bushing assembly
Features::
It is suitable for vertical movement, reduces the time of fixed seat support and assembly, and the surface is treated with electrolyte-free nickel plating, which is beautiful and corrosion-resistant.
Oil-free bushing linear skateboard
Features::
It is suitable for the relative movement between surfaces, with the advantages of self-lubrication, low friction and wear resistance, and can realize similar functions of slide rails, guide rails and other products, which is more economical, and the length and width can be freely specified.
