DX boundary lubrication Bushing DX, Marginally Lubricated Bearings, Yellow POM, Lead Free DX boundary lubrication bushing is based on a composite material with 3 firmly bonded layers:steel as backing, sintered bronze spherical powder as interlayer and modified POM as lining layer. It fits well for low speed, heavy duty and normal temperature and saves cost and prolongs working life when replacing normal all copper sleeves. If is widely applied in auto chassis, forging machine, metallurgical and mining machine, civil engineering, power station, strip rolling industries, etc.
Load capacity:70N/mm2
Temperature:-40°C~+120°C
Speed limit:2.5m/s
Friction coef(u):0.05~0.25
PV LIMIT(DRY):2.8N/mm2 .m/s
PV LIMIT(OIL):22N/mm2 .m/s
Reasons for Selecting composite bearing DX bushing 1.Good load capacity and anti-wear. 2.It is used in high load capacities and low speed with rotational ,oscillating or frequent stop-start motion. 3.It can work for a long time without oil in the condition of bounday lubrication,under oil or grease lubrication interval,the working-life will be longer. 4.It is machinable for the thicker of POM. 5.The bushes can be applied in auto chassis,forging machine,metallurgical,civil engineering,power station,strip rolling industries ect. 6.It is widely used in the machine where Lead is unacceptable. ♦ Features 1. DX Marginally Lubricated Bearings is for grease or oil lubricated applications. 2. DX Marginally Lubricated Bearings standard parts contain grease indents in the sliding layer, and plain sliding layer is also available on request. 3. DX Marginally Lubricated Bearings has optimum performance under relatively high loads and low speeds. 4. DX Marginally Lubricated Bearings is suitable for linear, oscillating and rotating movements. ♦ Process flow
♦ Application Automotive: Steering gear, power steering, pedal bushes, seat slides, king-pin bushes, tailgate pivots, brake caliper bushes, etc. Industrial: Mechanical handling and lifting equipment, machine slides, hydraulic cylinders, hydraulic motors, ski-lifts, pneumatic equipment, medical equipment, textile machinery, agricultural equipment, scientific equipment, etc.
