The benefits of oilless bronze bearings

Custom Made Bronze Bushing with Oil Groove Slide Bearing

Oilless bearings are the key components in mechanical equipment, and their good lubricating performance can ensure the stable and reliable operation of mechanical equipment. With the continuous improvement of structural requirements for various types of mechanical equipment, the requirements for bearing lubricating performance are also increasing. The oil groove structure has a great influence on the lubricating performance of the bearing.

Why open oil holes and oil grooves?

  • Oilless bearings are generally used in environments with high bearing capacity, and parts with high bearing capacity need more lubrication, otherwise, they are easy to lock. Therefore, oil grooves and oil holes are generally used for lubrication.
  • Where the sliding bearing environment is relatively harsh, part of the garbage can be brought out through the oil groove.
  • The oil-free bushing is generally self-lubricating bearings, which need a longer life, with oil grooves and oil holes. If you continue to refuel, your life will be longer.

Where should oil holes and grooves be located?

Oil holes and oil grooves can only be opened in the non-load-bearing area;
The axial oil groove cannot be opened along the bearing width to prevent end leakage.

The choice of oil groove arrangement and oil hole location has a great influence on the oil film carrying capacity. To ensure the custom bearing capacity, the bearing with a higher load is better not to open the oil groove. The oil hole of the bearing is best arranged in the low load area of the bearing. If the oil hole is arranged in the high load area, it will cause the oil film pressure leakage, destroy the bearing’s bearing capacity, and cause insufficient oil supply. The location should be chosen reasonably according to the calculation of the shaft track. Oil groove, oil hole edge must also be a smooth transition, so as not to tear the oil flow, damage the oil film, easy to form bubbles, resulting in cavitation damage.

Oil Groove Design

An oil groove is provided on the bearing surface to store lubricating grease and evenly smear the whole lubricating surface to reduce friction and mechanical wear.

We have extensive expertise in grooving and offer a full range of groove styles – from simple straight and circular grooves to double loops and double-figure eights.

Groove selection can be influenced by many things such as operating temperature, type of lubricant, supplemental lubrication feed system, load, etc. Any of the standard bearings listed in our catalog can be grooved, graphite, drilled, or re-machined in many ways to handle of variety of requirements.

Made From Self-Lubricating oilless brinze

Custom & Special Grooving Patterns

This shop is appropriately equipped with machinery for drilling, countersink and counter boring, thread cutting, and grooving all standard or special oil groove configurations. Self-lubricated and graphited bearings either plugged or grooved are available. Market-leading Bearings to Solve Your Engineering Challenges.

What is the best material for copper sleeves for equipment?

High hardness, excellent wear resistance, not easy to cause seizure, good composite bushing casting performance and cutting performance, good corrosion resistance in the atmosphere and freshwater.

Equipment copper sleeve material:

ZCuSn10Pb1

High hardness, excellent wear resistance, not easy to cause seizure, good casting performance and cutting performance, and good corrosion resistance in the atmosphere and fresh water.

It can be used for wear-resistant parts that work under high load (below 20Mpa) and high sliding speed (8m/s), such as connecting rods, bushings, bearing bushes, gears, worm gears, etc.

ZCuSn10Pb5

Corrosion resistant, especially to dilute sulfuric acid, hydrochloric acid and fatty acids.

Structural materials, corrosion-resistant and acid-resistant accessories, as well as crusher bushings and bearing bushes.

ZCuPb10Sn10

Good lubricity, wear resistance and corrosion resistance, suitable for bimetal casting materials.

Vehicle bearings, internal combustion engine bimetallic bearing bushes with a peak load of 100Mpa, piston pin sleeves, friction plates, etc.

ZCuPb15Sn8

In the absence of lubricants and water-based lubricants, it has good sliding and self-lubricating properties, easy cutting, poor casting properties, and good corrosion resistance to dilute sulfuric acid.

Bearings with high surface pressure and side pressure can be used to manufacture copper cooling pipes of cold rolling mills, parts with impact load up to 50Mpa, bimetal bearing bushes of internal combustion engines, mainly used for piston pin sleeves with a maximum load of 70Mpa, acid-resistant accessories .

ZCuZn38Mn2Pb2

It has good mechanical properties and corrosion resistance, good wear resistance and good cutting performance.

General-purpose structural parts, simple-shaped castings used in ships, instruments, etc., such as sleeves, bushings, bearing bushes, sliders, etc.

Material recommendation

1. ZCuSn6Zn6Pb3, ZCuSn5Zn5Pb5, can be used to manufacture bushings, gears, worm gears and other wear-resistant parts that work under moderate loads and speeds.

2. ZCuSn10P1 is a typical tin phosphor bronze with high hardness and wear resistance. It can be used to manufacture parts that work under heavy load, high speed and high temperature and are subject to strong friction, such as connecting rod bushings, gears, worm gears, etc. .

3. ZCuAl9Mn2, ZCuAl9Fe4, aluminum bronze have high strength, high density and stable chemical properties. Commonly used in valve bodies, worm gears, nuts, pipe fittings, etc.

4. ZCuZn25Al6Fe3Mn3 high-strength aluminum brass, with the highest strength among special brass. It has high strength, high hardness, high wear resistance, moderate plasticity and good corrosion resistance. Therefore, it is used to cast high-load wear-resistant weight on heavy machinery
