composite bearing material developed specifically to operate with marginal lubrication and consists of three bonded layers: a steel backing strip and a sintered porous bronze matrix, impregnated and overlaid with a acetal polymer bearing material. Oil Lubricated Bearings, Oil-free lubrication bearing (called DU abroad) is a high quality low carbon steel plate or bronze plate as the substrate. Sintered porous spherical bronze powder in the middle question, friction surface rolled modified polytetrafluoroethylene (PTFE and Pb) and through high temperature plasticization firmly combined into one three-layer self-lubricating bearing material, rolled into a sliding shaft. bearing. The material can provide good self-lubrication, wear resistance, low friction and other properties, giving full play to the strength of metal and modified plastic self-lubrication. The material can provide better self-lubrication, wear resistance, low friction and other properties, giving full play to the strength of metal and modified plastic self-lubricating properties. Oil-free bearings are divided into steel-based and copper-based.

Bushing Material structure

• Modified polytetrafluoroethylene
• Sintered spherical bronze powder
• Metal matrix
• Steel-based anti-corrosion coating

Bushing Typical Features

• Suitable for use under the condition of no lubricating oil, low frictional resistance, wear resistance and long service life.
• Suitable for use under various forms of motion such as rotation, reciprocation and oscillation.
• Stable low friction coefficient and excellent wear resistance under high load and low speed conditions.
• more effective under oil lubrication conditions, and can show high PV values in medium and high speed fields.
• Wide operating temperature range, can work in the temperature range of one 200°C ~ +280°C.
• Dynamic and static friction coefficients are basically close to each other, which can overcome the ~ crawl” phenomenon and run smoothly.
• Excellent corrosion resistance, can be used in various corrosive media (including liquid and gas).
• The bearing is thin-walled structure, light weight, occupying small volume, suitable for compact design.
• good dimensional stability, high mechanical strength, and good thermal conductivity.
• In the process of operation to form a transfer film, play a role in the protection of the grinding shaft, no bite shaft phenomenon.

• Hydraulic oil pump industry: mainly used in medium and high pressure gear oil pumps, vane pumps, piston pumps, etc.
• Automobile industry: shock absorber (guide sleeve), power steering, clutch, transmission shift lever, two scrapers
• The automotive industry: shock absorbers (guide bush), power steering, clutch, transmission shift lever, two wipers, steering gear shift and handbrake, ABS system, gasoline and diesel engine injection pump pedal support, trailer coupling head, and other applications

• Other: metallurgical industry, continuous casting and rolling mills, cement machinery, screw conveyors, hydraulic trucks, lift
• lift, micro motor, hydraulic motor, hydraulic equipment (cylinder guide sleeve), pneumatic equipment (cylinder guide sleeve), etc.
• Pneumatic equipment (cylinder guide sleeve)
• solenoid valve, medical equipment, fitness equipment, textile machinery, agricultural machinery, scientific research instruments, and
• thousand dry ovens, printing machinery, office equipment (printers, copiers and fax machines), butterfly valves, shut-off
• Valve, motorcycle (shock absorber) and other industries

Lead-free environmental protection bearing: is based on the compound PTFE material, according to the international environmental protection requirements and developed a new product. It is a new product developed on the basis of FZF01 material and in accordance with international environmental protection requirements. This product is widely used in general general machinery, because of the modified PTFE. It is especially suitable for food machinery, pharmaceutical machinery, tobacco machinery, etc. It is the direction of development of environment-friendly oil-free self-lubricating bearings. It is the direction of development of environment-friendly self-lubricating bearings. Hydraulic special bearings: is based on PTFE material, combined with the working principle of oil cylinder and shock absorber. It is a new type of material designed on the basis of bushing material and combined with the working principle of oil cylinder and shock absorber, which is more wear-resistant under the condition of no oil. In addition to the advantages of PTFE bearings, the product is especially suitable for frequent reciprocation of large lateral force occasions. Its performance is similar to that of foreign DP4, and it is suitable for automobile and motorcycle shock absorbers and various hydraulic cylinders.
