These facilities allow us to continually respond to customer demand for standard and customized products designed to improve comfort and reduce maintenance for shock absorbers, hinges, gears, pumps, valves, car seats, vibration dampers and other equipment requiring bearing materials.
Lead-free, environmentally friendly
Produced in a solvent-free process
High delivery performance
Broad product portfolio available
The POM 2Y sliding bearings MADE TO ORDER FROM CHINA are lead-free and constitute an improvement on the POM 2X bearings. They are used in sectors where lead must not be used, such as in textile machinery and vehicle steering systems, medium-speed applications or applications with medium loads and medium levels of grease lubrication.
Bronze Sleeve Bushing POM INCH SIZES made to order from china
Consists of a steel backing and a porous bronze intermediate layer
and overlaid with modified polymers ( POM ).Indents on the surface
of the polymer are designed for better distribution of the
lubrication (oil or grease) between the bearing and themating
material. The steel back provides the bush with higher mechanical strength and load capacity. Moreover, the steel backingis plated with a corrosion protection
layer. Products of POM series are applied in automotive
chassis, forging machines,
cranes, presses, agricultural equipment, etc.
Instructions for installation of oil-free bearing production and
application
concept
It has the characteristics of high bearing capacity, impact
resistance, high temperature resistance, strong self-lubrication
ability, etc., especially suitable for heavy load, low speed,
reciprocating sliding bearing or swinging, etc., which is difficult
to lubricate and form oil film, and is not afraid of water flushing and other acid oil-free bearing
corrosion and erosion.Generally speaking, inlaid bearings not only save fuel and energy, but also have longer working life than ordinary sliding bearings.At present, the products have been widely used in metallurgical
continuous casting machines, rolling equipment, mining machinery,
ships, steam turbines, water turbines, injection molding machines
and equipment production lines.
Installation instructions
1. It should be determined whether the self-lubricating bearing
surface of the shaft and shaft shell has bumps, protrusions, etc
2. Whether there is dust or mold sand attached to the surface
of the bearing shell.
3. Although it is a small bump, protuberances, etc., if there is an
oil grindstone or fine sandpaper to remove.
4. A small amount of lubricating oil should be applied to the
surface of the shaft and shaft shell in order to avoid collision
during the installation.To mount the bearing on the shaft, apply
force on the inner ring; to mount the bearing on the
housi method ng, apply force on the outer ring.To be in the
bearing force, be careful to make the force vertical and uniform
down, deflection will cause bearing injury.To this end absolutely
try to avoid wide - hitting.
5. Oil-free bearing retainer and sealing plate are also absolutely
not applicable.The hammer and casing installation method is a
common method, because it will damage the bearing, so do not hit
directly.Be as shown in the general, so that the sleeve in the
middle and beat in.The hammer should be struck lightly.In the
mechanical structure, when the inner and outer rings are tightly
matched, the backing plate should be used to make sure that the
force can be applied to the inner and outer rings at the same
time.If only in the inner ring add force pressure, the force must
be the ball and pressure into the outer ring, therefore, will cause
scars in the orbital plane.To install the bearing with large margin
on the shaft, it is widely used to heat the bearing to 80~90
degrees and expand the inner diameter in clean oil.
6. The hardness of the bearing may be reduced by overheating, so it
must not exceed 100 degrees.At this point, the bearing must be
suspended using steel wire, or placed on the wire mesh, support
plate, do not place at the bottom of the groove.When the bearing
reaches the desired temperature (below 100 ° c), it should be
immediately removed from the groove and quickly inserted into the
shaft. The bearing will contract with the temperature drop, and
sometimes there will be a gap between the shaft shoulder and the
end face of the bearing. Therefore, it is necessary to use tools to
press the bearing in the direction of the shaft.
Application
POM lubricated bearing: acid polymethylaldehyde with high wear resistance. It is necessary to assemble with oil storage pit when the bearing
surface is arranged regularly
With grease, especially suitable for high load under the low speed
of rotation, swing movement and often under load negative, opening
and closing and less prone to forming fluid lubrication parts,
under the condition of boundary lubrication, can use for a long time without refueling and maintenance, and in the
process of gas can be used to more prolong the service life of
bearing, currently applicable to the metallurgical machinery, mining
machinery, hydraulic machinery, auto parts, construction machinery,
agricultural machinery, etc.
Oil-free self-lubricating bearing: this product is a mixture of
steel plate, sintered spherical bronze powder in the middle layer,
rolled ptfe and lead in the surface layer.It has the
characteristics of low friction coefficient, wear-resisting and corrosion-resistant, oil-free self-lubrication
and long service life, which can reduce cost, reduce noise, prevent
from sticking and sliding.It is widely used in sliding parts of all kinds of machinery, such
as printing press, textile machine, hydraulic truck, tobacco
machine, medical machinery, fitness apparatus, micro-motor,
automobile, motorcycle, etc.
Metal base inlaid solid self-lubricated bearing: it is a new
lubricated bearing with both the characteristics of metal bearing
and self-lubricated bearing. It is loaded by the metal matrix and
lubricated by the special formulation of solid lubricated
material.It has the characteristics of high bearing capacity,
impact resistance, high temperature resistance and strong
self-lubrication ability.Traditional oil-bearing: because of its
advantages of low noise and self-lubrication, oil-bearing has
become the new favorite of computer CPU fan bearing, and the market
demand is large.In addition, with the increasing demand for noise,
the application of oil-bearing in household appliances is
expanding.
The basic requirements of bearing materials depend largely on the
working performance of the bearing.The selection of suitable
materials for rolling bearings will have a great impact on their
service performance and life.Generally speaking, the main failure
modes of rolling bearing are fatigue spalling under the action of
alternating stress and loss of bearing precision due to friction
and wear.In addition, there are cracks, indentation, corrosion and
other causes of abnormal damage to the bearing.Therefore, rolling bearings should have high resistance to plastic deformation, less friction and wear, good rotation accuracy, good dimensional accuracy and stability, and long contact fatigue life.And many of these properties are determined by materials and heat
treatment processes.
