Wrapped composite sliding bearing, copper/tin plating
Suitable for dry running with a low coefficient of friction
Low wear rate, good sliding performance
Suitable for rotary and oscilating movement
High chemical resistance, low absorption of water and reduced swelling.
Cylindrical and flanged bushing, thrust washer, strips.
Standard or non-standard, on demand!
DIN 1494/ ISO3547
HLDB-10 metal-polymer composite bushings also named as SF-1 are backed with copper-plated steel with porous bronze sintered on the steel and polymer(PTFE) imbedded into the bores of the bronze. By combining the metals and polymer together, it provides good capacity of anti-abrasion and self-lubrication with lower friction coefficient. The steel back is plated with a erosion prevention layer.
|Very low speed||140N/mm2||Max.speed||Dry rynning||2m/s|
|Rotating oscillating||60N/mm2||Hydrodynamc poeration||2m/s|
|Max.PV dry running||Short-term operation||3.6N/mm2*m/s||Heat Conduction Coefficient||42W(m*K)-1|
|Continuous operation||1.8N/mm2*m/s||Thermal Expansion Coefficient||11*10-6K-1|
HLDB-10 is widely applied for automotive, such as tractors, auto machines, calipers and pistons and so on. Besides that, it is also widely used in business machines, home appliances, hydraulics and valves. For example pumps, weaving, etc.
