KDB-10 Self-lubricating Multi-layer Composite Bearings
High-quality low carbon steel, stainless steel or tin bronze as a substrate, the center of the sintered spherical porous bronze powder, and the surface of the PTFE-based mixture firmly embedded. These products give full play to the advantages of metals and polymers, with a low coefficient of friction, good wear resistance and self-lubricating properties. The bearings are molded by roll extrusion process, and the steel backing can be copper, tin or zinc plated as required.
-
KDB20 Boundary Lubricated Bearings
With high-quality low-carbon steel, stainless steel or tin bronze as the matrix, spherical porous bronze powder is sintered in the middle, which is firmly chimeric with polymer materials such as surface modified POM and PEEK.There are oil storage pits on the surface of the material, so as to achieve good lubrication between the friction pairs, with good wear resistance and carrying capacity.The bearing is formed by rolling extrusion process, and the steel back can be plated with copper or tin as needed.
-
KDB30 Bimetal Bearings
It is based on high-quality low-carbon steel or medium-carbon steel, and the surface is covered with copper powder alloy, which has been sintered and rolled many times to improve the density and carrying capacity of the alloy.Oil holes, oil sumps or stamping oil holes can be rolled on the surface of the alloy to facilitate the storage and transportation of lubricating oil and effectively reduce wear.The bearing is formed by rolling extrusion process, and the steel back can be plated with copper or tin as needed.
-
KDB50 Solid Lubricated Bearings
With specially formulated copper alloy castings as the matrix, it has high mechanical properties, good casting properties and corrosion resistance.In order for the bearing to be self-lubricating, holes are drilled at a certain angle and density on the alloy casting matrix in advance, and a specially formulated self-lubricating solid lubricant is inlaid in the hole.The bearings are formed by precision machining.
-
KDB60 Steel Sleeve Bearings
Carbon steel or alloy steel is used as the matrix, which has high mechanical properties. In order to facilitate the storage and transportation of lubricating oil to reduce wear, different forms of oil sumps, oil holes or oil holes can be processed on the surface of the material, and then different forms of heat treatment are carried out to improve the surface hardness and wear resistance.Most of the bearings are formed by precision machining.
-
KDB-800 Cast Copper Alloy Bearings
With specially formulated copper alloy castings as the matrix, it has high mechanical properties, good casting properties and corrosion resistance.In order to facilitate the storage and transportation of lubricating oil to reduce wear, different forms of oil tanks, oil holes or oil holes can be processed on the surface of the material.The bearings are formed by precision machining.

KDB-2000 Single-layer zero-clearance Self-lubricating Bearings
With tin-bronze mesh, stainless steel mesh or aluminum mesh material as the matrix, it is firmly chimeric with PTFE-based mixed polymer material. It gives full play to the advantages of metal mesh and polymer, with low coefficient of friction, good wear resistance, corrosion resistance and self-lubricating properties.While meeting the requirements of lightweight, low noise and constant torque, flexible installation without gaps is realized.The bearing is formed by rolling extrusion process.
-
KDB-2100 Two-layer bonded Self-lubricating Bearings
It is based on galvanized steel, stainless steel or aluminum sheet material, and a layer of PTFE-based polymer is bonded to the surface, which has a low coefficient of friction, good wear resistance, corrosion resistance and self-lubricating properties.The thicker PTFE belt layer can be installed with interference to meet the design requirements of different torques, and it has the effect of damping and noise reduction.The bearing is formed by rolling extrusion process.
New Energy Facilities
Various series of KDB bearings have been widely used in new energy (photovoltaic, wind power, hydropower) support swing and transmission system to meet the long life of more than 25 years of working conditions, including self-lubricating multi-layer composite bearings, casting copper alloy bearings and so on.
Construction Machinery
KDB various series bearings have been widely used in various parts of chassis travel mechanism, body parts, hydraulic components and other parts. Copper alloy inlaid solid lubricant bearings and self-lubricating multilayer composite bearings, etc. These bearing materials have excellent wear resistance and dust resistance under high load conditions, while the self-lubricating technology makes the maintenance cycle of the bearings greatly extended, improves the utilization rate of the equipment and reduces the maintenance cost.
Automotive Industry
At least 30 or more parts of a passenger car are equipped with self-lubricating bearings.For example: tensioner wheel, air conditioning compressor, secondary air valve, fuel pump, starter motor, gearbox, steering pump, steering column, shock absorber, braking system, pedal assembly, seat adjustment system, door hinges, luggage compartment hinges, hood hinges, windshield wipers, solenoid valves, and electric drive.
