Advantages of self-lubricating bearings
Modern design for today's self-lubricating bearing materials is
creating a huge demand. Maintenance-free is required even under
severe extreme operating conditions and maximum load conditions.
With the continuous improvement of cost requirements, enterprises
have higher and higher requirements for the reliability of
equipment and plant operation. Metal self-lubricating bearings can
satisfy the maintenance free and self-lubricating conditions in
long-term use, which makes the design of reliable long-term
self-lubricating system possible. Metal-type self-lubricating
bearing materials can be widely used in high load and low speed
conditions of rotation, swing and linear reciprocating motion, but
also suitable for the traditional lubrication can not be reached or
is prohibited to use the occasion, or in special conditions such as
dust, impact load or irradiation conditions need long-term and
stable use
When your application calls for lubrication for either the housing or the shaft, an oil or grease groove is essential. At Bronze Bearings, we can groove parts to our customer’s specifications, including single loop, figure eight, double loop, double figure eight, half figure eight, straight, and circular groove patterns.
CUSTOM MACHINED PARTS
Grooving
When your application calls for lubrication for either the housing
or the shaft, an oil or grease groove is essential. At Bronze
Bearings, we can groove parts to our customer’s specifications,
including single loop, figure eight, double loop, double figure
eight, half figure eight, straight, and circular groove patterns.
We are both manufacturers and distributors of bronze bearings and
custom bronze bearings. Our production processes include turning,
boring, broaching, grooving, dressing, milling, drilling, grinding
and deburring. Our standard ranges of bronze bushings and bronze
sleeve bearings are available in a wide variety of sizes and shapes.
We have thousands of cast bronze bushings, sintered bronze
bushings, flanged bushings, thrust bushings and more in stock. Our
standard bronze bearing ranges are supplied with internal grease
grooves and without grooves.When quotes are made for pads that are
"machined to print" or "made from samples", we welcome designs in a
number of formats, such as; Adobe .pdf, Microsoft Word, Koday .jpeg
and CAD file to meet the needs of our customers.
Oil groove brass bush. Based on high-strength brass lubricated by the addition of oil in the groove, which has the same performance as the tin bronze bushing but has a much higher hardness, the service life for low speed application is twice that of the tin bronze bushing. It can be used under heavy load conditions.
Oil groove copper sleeve bushing Made-To-Order Choose
your dimensions.
Machined Cast bronze bushings offer technically and economically
favourable bearing solutions. High loading capability, low weight, good corrosion resistance. VIIPLUS Sliding Bearing can offered different types bronze alloys
according to the life time, service etc. The tolerance is much
higher than wrapped bronze bushes.Our Precision Bronze
Bushings are machined from various kinds material :

There are the following raw materials for bronze bushings:
ZCuSn10Pb1: corrosion resistant, especially to dilute sulfuric
acid, hydrochloric acid and fatty acid.Construction information,
corrosion and acid resistant accessories, crusher bushing, bearing
tiles.
ZCuSn10Pb5: smooth, wear resistant and corrosion resistant,
suitable for bimetal forging materials.Bearings for vehicles,
bimetallic bearing pads for internal combustion engines with peak
load up to 100Mpa, piston pin sleeves, friction plates, etc.
ZCuPb10Sn10: high hardness, excellent wear resistance, not easy to bite dead
appearance, good forging and cutting function, in the atmosphere and fresh water has good corrosion resistance.It can be used for wear-resistant parts under high load (below 20Mpa) and high sliding
speed (8m/s), such as connecting rod, bushing, bearing bush, gear,
worm wheel, etc.
ZCuPb15Sn8: under the condition of lack of smoothing agent and
water quality smoothing agent, sliding and self-smoothing function
is good, free cutting, forging function is poor, good corrosion
resistance to dilute sulfuric acid.Bearing with high external
pressure and side pressure, can be used to make copper cooling tube
of cold rolling mill, parts with impact load up to 50Mpa, bimetal
bearing shell of internal combustion engine, mainly used for piston
pin sleeve with maximum load up to 70Mpa, acid-resistant
accessories.
Based on high strength brass, lubricating by oil added in the
groove, which has the same performance with tin bronze bushing but
with much higher hardness, the life time for low speed application
is 2 times of tin bronze bushing. It can be used in heavy load
condition.
It mainly used in the joint of grab which with high load, and in
the huge gear box.
