Product Description

We offer high quality Oilless Bearings, Bushings...Plain bearing Strips Material Sliding Bearings SF-1B bronze base material | VSB-11 Strips

Bronze base bearing self-lubricating bearing tin bronze is of high safety factory,and is particularly appropriate for high temperature environment 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 convery ers for cement.It can also be composed in steel housing or fabricated into Flanged bushes which can move both in radial and in axial directions.

Bronze base bearing self-lubricating bearing tin bronze, bearing sleeve for metallurgical iron and steel industry, bearing sleeve for continuous caster billet raceway, bearing for equipment in front of high temperature furnace, bearing sleeve for cement grouting pump and screw conveyor.


Bronze base bearing is made of tin bronze as matrix, sintered bronze spherical powder in the middle, rolled PTEE on the surface and high temperature resistant filler material.
It has a high safety factor, in the continuous work can not stop repair places and high temperature can not be refueled in places.At present, it has been widely used in metallurgical iron and steel industry, continuous casting machine billet runner, high-temperature furnace equipment, cement grouting pump and screw conveyor.It can be combined with steel sleeve, also can be made into flanging, to achieve the end face, inner hole friction effect at the same time.


The grouting pump is designed to overcome the shortcomings of the above existing technologies, provide a kind of ground source heat pump ground pipe backfilling equipment that is convenient to transport, install, operate and use, easy to maintain and repair, and can meet all grouting filling requirements in the environmental protection geothermal application construction.


The pump head of the grouting pump is mainly composed of the pump head, bearing, shaft sleeve, self-lubricating bearing, ball valve seat, inlet valve cover, exhaust valve cover, steel ball and so on. In order to ensure the smooth next grouting, please be sure to clean the pump and pipe after grouting.

The rolling part of the bridge support is to replace the pure PTFE plate with the thickened vsb-11 wear-resistant layer.Up to 130N/mm carrying requirements.


PTFE skidway plates or skidway plates


SF-1B bronze-based material is made of tin bronze plate as the base, sintered bronze spherical powder in the middle, surface rolled PTFE and high temperature resistant filler. It has a high safety factor and is particularly suitable for use in places where continuous work cannot be stopped and where it cannot be refueled at high temperatures. At present, the material has been widely used in the metallurgical steel industry, continuous casting machine billet rolling, high temperature furnace front equipment, cement grouting pump and screw conveyor. It can be combined with steel sleeves on the outside or flanged to achieve the effect of friction between the end faces and the inner holes. The sliding part of the bridge support is to replace the pure PTFE board with the SF-1B wear layer thickening product. Meet the requirements of 130N/mm2 load bearing.

VSB-11 Metal-Polymer Bronze Backed PTFE Plain Bearing
Bronze + Bronze Powder + PTFE/Fibre(DU-B)



· VSB-11
· Very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Suitable for lubricated applications
· Suitable for linear, oscillating and rotating movements
· Bronze back offers improved corrosion resistance in humid/saline environments
· Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surface, suitable for rotary and oscillating movement. Very high chemical resistance, low absorption of water and swelling, also performs very good lubrication feature, the bronze backing provides the improved corrosion resistance comparing with VSB-10.



1. PTFE/fibre mixture thickness 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE/Fibre mixture.
3. Bronze backing, provides exceptionally high load carrying capacity, excellent heat dissipation and very good corrosion resistance.
