SF-2 boundary lubrication bearing BOUNDARY LUBRICATED BEARING SF-2 (BUSH)

Quick Details

SF-2 boundary lubrication bearing with steel as matrix, a middle burning type cabbage bronze powder, rolling surface modified Polyoxymethylene (POM), and contains oil storage pit. It is suitable for low speed and heavy duty place under normal temperature condition, instead of the traditional copper sleeve, it can not only reduce the cost but also prolong the service life. Products are widely used in the field of automobile chassis, forging and pressing machine, metallurgical and mining machinery, engineering machinery, water, electricity, steel rolling industry. the maximum bearing pressure: 70N/mm2 friction coefficient: 0.05~0.25 temperature range: xml:namespace prefix -40 ~130 DEG maximum sliding speed: 2.5m/s  is allowed; The highest PV value: 22N/mm2.m/sSF-2 boundary lubricated bearing 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 has oil pocket for oil lubrication.It fits well for slow speed, heavy duty under normal temperature.It can save cost and prolong working life when replacing normal bronze bush.It can lower frquency of adding oil, simplify replaement process when it is used on rolling mill.It is widely applied in chassis of automobile, forging machine, metallurgical machine and mining machine, construction machinery, hydropower rolling, mill etc.Load capacity:70N/mm2   & nbsp; &nbs; P; Temperature:-40 degrees C~+130 degrees C & nbsp; speed limit:2.5m/s
