HZ1B Type 1 copper-based self-lubricating bearing

Material Features

HZ1B is of high safety factory. and is particularly appropriate for high temperature enviranment where no oil is effcient and where the machine must be under successive long period working condition. This is widely used in steel metallurgy industry such as bushes for roller grooves of successive casting 'machines. cement grouting pumps and screw converyers for cement.lt can also be composed in steel housing or fabricated into Flanged bushes which can move both in radial and in axial directions. It can be applied in bridge bearing plate because of thicker inner surface Layer to arrive 130N/mm².

Application Characteristics

Low friction coefficient and good dry friction performance

Suitable for linear, swinging, and rotating movements

No slipping or crawling during the operation

Bronze substrate exhibits excellent rust and corrosion resistance in humid salt environments

Corrosion resistance and good thermal conductivity

Applied to metallurgy, continuous casting machines, and cement screw pumping machines

Tin bronze+porous sintered copper+PTFE/special filler (black)

Application Feature

1. PTFE and Friber can protect the shaft. while the machine in operatron.

2. It can be composed in steel housing. or fabricated into flanged bushes which result in function for
montion both on flange and I.D.

3. It is widely used in steel metallurgy industry. such as bushes for foller grooves of successive casting machines. cement grouting pumps and scrow conveyers of machine.

4. Aronze have gaod thermal

5. It can be applied in the machine, working long time. which examine and repair is incapable. because the bronze can lubricate itself.

6. It is used in the feeble acid and alkali condition because of good anti-corrosion of bronze backing.

7. Good load capacity.

Material Structure
