Marginal Lubricating Lead Free Self Lubricating Bushings Non Oil Bearings

Marginal Lubricating Lead-Free Bush , Non-oil Lubricated Bearings, Non-oil Bearings

SF-1 non-oil lubricated bearings are high-quality low-carbon steel as the base, the middle sintered spherical bronze powder, surface rolling polytetrafluoroethylene (PTFE) and lead mixture is made of rolling sliding bearings. And have a small coefficient of friction, wear resistance, corrosion resistance and good oil-free lubrication characteristics. To use the product can reduce costs; reduce mechanical noise and so on. Has been widely used in various mechanical sliding parts, such as printing presses, textile machines, tobacco machines, exercise machines, hydraulic pallet truck, hydraulic pumps, automobiles, motorcycles and agro-forestry machinery.
 
Are widely used in automated machinery and equipment (telescopic, swinging, sliding, swing and other parts) and hydraulic cylinder guide sleeve, plastic molding machines, die-casting machines, rubber machinery, hydraulic handling vehicles, printing presses, textile machines, tobacco machines, micro-motor , automobiles, motorcycles and forestry machinery and so on.
 
SF-2 boundary lubricated bearings are high-quality low-carbon steel plate as the base, the middle layer of porous sintered bronze layer, the surface layer of modified POM rolled. The product load is good, good wear resistance. For high load low speed rotary motion, oscillating motion, and often frequent and difficult to load hoisting the formation of hydrodynamic lubrication occasions. In the boundary lubrication conditions, in the long term without refueling and maintenance, refueling in the over layer so that a longer bearing life. The surface of plastic layer in the processing molding can be left a certain margin, the assembly seating whole pressure on their own after processing, in order to achieve better assembly dimensions. Products are mainly used in auto chassis, metallurgical machinery, mining machinery, irrigation machinery, construction machinery, agricultural machinery, steel rolling equipment.
Maximum load pressure: 70N/mm2 friction coefficient: 0.05 ~ 0.25
Suitable temperature range: -40 ~ +130 degrees Celsius to allow the maximum PV value: 2.8N/mm2.m/s
The maximum sliding speed: 2.5m / s to allow the maximum PV value: 22N/mm2.m/s
 
Its advantages: thin wall, small size, light weight, carrying a high friction coefficient is small, high temperature, pollution-free, easy installation, low-cost, durable. For user enterprises improved product design rationality, economy and the current green needs. ..
