PTFE skidway plates or skidway plates VSB-11 Dry Sliding Bearing Strips are specifically designed for oscillating and rotating movements. These bearing strips are made of polytetrafluoroethylene (PTFE), also known as Teflon, which possesses excellent properties such as low friction, high chemical resistance, and high temperature tolerance.
The VSB-11 Dry Sliding Bearing Strips are commonly used in various industrial applications where oscillating or rotating motions are involved. Their dry sliding properties eliminate the need for lubrication, thus simplifying maintenance and reducing the risk of contamination.
The skidway plates feature a smooth surface that ensures consistent and reliable sliding, even under high loads and varying temperatures. They are also lightweight and easy to install, making them a convenient choice for a wide range of applications.
Overall, PTFE skidway plates or skidway plates VSB-11 Dry Sliding Bearing Strips are an effective solution for supporting oscillating and rotating movements in various industrial settings.
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.
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
CHARACTERISTICS
· 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.
