In the inner bronze alloy surface can be processed with various types of oil grooves, oil hole and oil pockets according to the different working applications, to suitable for the conditions which can not continuously put oils or difficult to apply the grease.
Material can get good bonding strength and the best bearing capacity by two times of sintering.
(also known as JF-800; SJ)
MQ-090 bronze wrapped bushing, using tin bronze alloy CuSn8P/CuSn6.5P for material, Surface rolling diamond pockets, to store grease or graphite powder ,to rapidly build up a lubrication film at the start of movement and thereafter reduce the startup & running friction;
it has good fatigue strength and bearing capacity, corrosion resistance, wear resistance.
Widely used in agricultural machinery, forestry machinery,building machinery, construction machinery, such as high load low speed occasions.
(also known as FB090 or B09)
MQ-092 wrapped bronze bushing, using tin bronze alloy CuSn8/CuSn6.5 for material, with oil holes according to a certain angle, easy to form oil film at startup, thereby reducing startup & running friction coefficient.
It has good bearing capacity, corrosion resistance and wear resistance. This series of products are widely used in agricultural machinery, forestry machinery, construction machinery, construction machinery and other high load low speed occasions.
(also known as FB092)
MQ-09G are similar to the MQ090,except there are solid lubricants embedded into the diamond shaped pockets on the bearing surface,which provide perfect lubrication at the startup & running,even with a lack of oil.
It can be used in contruction machinery,gear boxes,automotive clutch parts,forestry machinery,etc.
MQ-08G is similar with the MQ09G,except for: replace bronze with steel backing,to save the costs, ecomonic & more loading capacity.
Widely used in construction machinery,machine and machine tool,brake system of automobile ,etc.
MQ-091 is similar with MQ090,except for:replace bronze with copper CuZn31Si(H68) or CuZn37Si(H62),to save the costs,ecomonic & more loading capicity.
MQH-090/092 : compared to the normal MQ090/092,with higher Hardness;the corresponding bearing capacity and wear resistance are stronger, to adapt to a wider range of products, longer service life.
MQ-FR(FR) soft strip material consists of a bronze mesh shell, laminated with compounded PTFE tape.
It is widely used in car door hinges, joint bearings, medical industries, food industries, textile machines etc. The standard wall thickness is 0.48+-0.02 mm.
FD Soft strip is composed of PTFE and bronze powder, it is fabricated by using mould to press and then sinter. It has the advantage of lower friction and lower wear and powerful tensile strength.
FD can be used with oil or without oil, so it is the best choice for machine tool slide guide, automobile absorber, piston ring, and so on.
MQ650 solid inlay bearing, is a high-performance solid lubricating product on a high-brass base, inlaid graphite or MoS2 solid lubricant. It broke through the general bearing to rely on the limitations of oil film lubrication. In the course of the use of friction heat through the solid lubrication and shaft friction, the formation of oil, powder coexistence of lubrication of the excellent conditions, both to protect the shaft does not wear, but also the solid lubrication characteristics of the eternal. Its hardness is twice as high as that of ordinary copper, and the wear resistance is twice as high.
At present, the product has been used in metallurgical caster, train stent, rolling equipment, mining machinery, ships, gas turbines and other high temperature, high load, low speed and other occasions.
