Because of its light weight, low cost and maintenance-free, self-lubricated bearings are widely used in all kinds of fitness and entertainment equipment.Metal-Polymer Anti-Friction Plain Bearings self-lubricating Bearings Cylindrical PTFE for belt conveyor.
Interpret the skill transformation of food belt conveyor Bushing & Bearings
China's agricultural products deep processing industry to transport
network belt not only expect quantity, stainless steel network belt and more technology water steep dry bearing steep
function, quality.This points out a bright way for the development
of China's transport network and belt industry.
Plastic bearing seat is indispensable in the transmission of food
belt transport machinery and equipment important components, in the
production and transport operations can be better forward transport
equipment transmission power, and then play a role in reducing
energy consumption.In the process of the development of modern
sliding bearing technology and skills, in order to make the bearing
seat very good forward bearing ability, China has made relatively excellent innovation in terms
of the function and material of the bearing seat, and adopted
engineering plastics to make the bearing seat.Plastic bearings have
been tested to be more rigid and rigid than steel bearings, so they
are used in different types of food belt conveyors.
Low power consumption of belt conveyor accessories.As there is no relative movement between the material and the
delivery belt, not only the operation resistance is small, but also
the wear and breakage of the cargo are small, the yield is high.All
these are advantageous to reduce production cost.
Belt conveyor accessories transport line habitual strong and
active.The length of line composite bearing depends on the need.It can be as short as a few meters and as long
as more than 10km.They can be installed in small tunnels or over
ground traffic disturbances and risk areas.
Belt conveyor accessories can be very flexible to receive material
from one or more points depending on the skill flow.It can also be
discharged to multiple points or sections.Belt conveyor accessories
become a primary transport trunk when they are delivered together
at several points to the belt feeder (such as the conveyor
accessories under the coal bin of the coal preparation plant) or
along the belt conveyor accessories at any point in the length
direction of uniform feeding equipment.
Belt conveyor accessories can be used to pick up materials in the
roadway below the coal yard pile and, when needed, mix different
materials from different piles.Materials can be simply unloaded
from the accessories head of the conveyor, or can be unloaded at
any point in the length direction of the conveyor belt by the
plough type unloading device or by the moving unloading
truck.According to the needs of transportation skills, it can be a single unit, or more than one set of transport
equipment or other transport equipment to form a horizontal or skew
transport system to meet the needs of different types of operation
lines.
Food belt delivery machinery traditional plastic bearings are based on a single engineering plastic material.Over the years, the use of habits of a wider range of planning
needs, especially food, medicine, drinks and other operations on
the production environment, equipment reliability, equipment
operation power needs to continue to advance, a variety of
composite plastic bearing seats play an increasingly important
role.
Plastic bearing base by adding composite fiber filler, can reach high compressive resistance, heat resistance and creep resistance, composite fiber itself has
excellent resistance function;Participating in solid grease, the
selected constituent material and composite fiber are combined to
help reduce resistance.Plastic bearing housing has excellent
resistance function, but also has high precision, low thermal expansion rate, low water absorption
rate, high compressive stress, creep resistance high-grade
characteristics.
Plastic bearing seat production material, as a new type of high
molecular material, the resistance coefficient is small, from the
wear loss property, plastic bearing seat production material than
the usual carbon steel material bearing seat more wear resistant,
but also has the characteristics of self-lubrication.
The condition of self-lubricity is that the cohesion between
molecules should be small, the atoms in the molecular structure are
placed symmetically, other lubrication functions and lubrication
conditions.Plastic bearing seat surface strength ratio high and
very lubrication, basically do not appear tension, with excellent self-lubrication function and low resistance coefficient,
on the basis of adhering to the traditional advantages of plastic
bearing seat, can be used in production operations compared to fine
or high speed operation of the transport operation.
Plastic bearings can work well in alkaline environments, but not in
corrosive environments rich in acid.The rigidity of plastic bearing
seat is large, the hardness is high, even in the operating
environment with low temperature contrast, the strength of impact force is also high.
The self-lubricating bearings are light, cost-effective and maintanence free, So they are widely used to various kinds of body fit equipment and .
ROLLED DRY SLIDING BEARINGS (PTFE)
Steel + Bronze Powder + PTFE/Fibre(DU)
Wrapped PTFE Lined (maintenance-free), self lubricated plain or flanged bearings, thrust washer and strip, Carbon steel shell with sintered bronze layer filled with PTFE
VSB-10 Self-Lubricating Multilayer Composite Bushing
Bushing material suitable for lubricated applications
self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
Anti-friction bearing suitable for linear, oscillating and rotating movements
Material is designed to operate without supplemental lubrication and will perform excellent when lubrication is present. Low friction, low wear rate, good sliding characteristics and very low absorption are a few of the features of this material. VSB-10 bushings will support rotary, linear and oscillating motion.
1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the
rotating shaft. Minute partides of the PTFE layer and the sintered bronze material combine to create a solid
lubricant film, which coats the shaft.
2. Sintered bronze powder thickness 0.20*0.35mm,A special composition of powdered
copper is thermally fused to the steel backing. This contact layer
acts as an anchor for the PTFE layer and conducts the thermal build
up away from the bearing surfaces.
3. Low-carbon steel backing. Setting the foundation of the bushings, the steel
back provides exceptional stability, load carrying and heat
dissipation characteristics.
