Low wear rate, good sliding performance
Suitable for rotary and oscilating movement
Very high chemical resistance, low absorption of water and and reduced swelling.
Cylindrical and flanged bushing, thrust washer, strips.
Standard or non-standard, on demand!
DIN 1494/ ISO3547
HLDB-1B bushing also named as SF-1B, meets the demanding criteria for long life and trouble-free performance with or without lubricant or of high safety factor. The bronze backing provides a high corrosion resistance, anti-magnetic properties and a good thermal conductivity. This type of bushing is particularly appropriate for high temperature environment where no oil is efficient and the machine must be under successive long period working condition.
|Very low speed||140N/mm2||Max.|
|3.6N/mm2*m/s||Heat Conduction Coefficient||60W(m*K)-1|
|1.8N/mm2*m/s||Thermal Expansion Coefficient||18*10-6*K-1|
HLDB-1B is typically applied in steel metallurgy industry such as bushes for roller grooves of successive casting machines, cement grouting pumps and screw conveyers for cement and so on.
