When selecting Bronze POM (Polyoxymethylene) bushes with a thrust washer composite, metric thickness is a crucial factor to consider. The thickness of these components directly affects their performance and durability in various applications.
Bronze POM bushes are commonly used in machinery and equipment due to their excellent wear resistance, mechanical strength, and self-lubricating properties. When combined with a thrust washer composite, they provide an even more robust solution for applications that require high thrust loads and precision movements.
The metric thickness of the Bronze POM bush determines its ability to withstand compression and impact forces. A thicker bush can offer greater strength and durability, but it may also increase the overall size and weight of the component. Conversely, a thinner bush may be more suitable for applications with limited space but may not provide the same level of strength.
The thickness of the thrust washer composite is also important. This component supports the bush and helps distribute the thrust load evenly. A thicker thrust washer can provide more support and stability, while a thinner one may be sufficient for applications with lower thrust loads.
It's important to consult with a manufacturer or supplier to determine the appropriate metric thickness for your specific application. They can provide expert advice based on your requirements, such as the expected thrust load, operating conditions, and space constraints.
In summary, the metric thickness of Bronze POM bushes with thrust washer composites is a crucial factor to consider when selecting these components for your machinery or equipment. The appropriate thickness can ensure optimal performance, durability, and suitability for your specific application.

Boundary Lubricating Bearings Black POM Bushes lead-free POM Lined Bushing
Boundary lubricated bearing is a sliding bearing with steel plate as the matrix, sintered spherical bronze powder in the middle and rolled round oil storage hole black modified polyformaldehyde (POM) material on the surface
Electro-hydraulic grooving machine grooving machine press wheel shaft sleeve press wheel bearing worry-free bearing
Bushings Material structure
1. POM 0.30-0.50mm modified polyformaldehyde has good wear resistance, and even in
the case of instantaneous oil shortage, it also has a low friction
factor.Bearing surface is arranged with a spiral Angle of the oil
sump pit, assembly, must be coated with grease.
2. Copper powder layer 0.20~0.35mm, with good bearing capacity and wear resistance, good thermal
conductivity can timely transfer the heat generated in the process
of bearing operation.The composite material can infiltrate into the gap of copper powder
ball and improve the bonding strength.
3. Low carbon steel, providing bearing capacity and heat transfer
function of the bearing.

1. Outside diameter: ring gauge pass (GO) and stop (NO GO) mode is
adopted. The through end of ring gauge is the maximum size of
outside diameter, while the end of ring gauge is the minimum size
of outside diameter.
2. Inner diameter: press the shaft sleeve into the reference hole
(H7 median tolerance) and test the shaft sleeve with cylindrical
plug gauge. The through end of the plug gauge is the minimum size
of the inner hole of the shaft sleeve, and the end end of the plug
gauge is the maximum size of the inner hole of the shaft sleeve.The
accuracy grade of the inner hole of the rolling shaft sleeve is H9.
Ring gauge and plug gauge size according to DIN1494 part.
Metal-polymer marginal lubricating composite materials consist of metal backing sintered porous bronze with POM or PEEK polymer as working layer. Steel backing provides exceptionally high load carrying capacity, excellent heat dissipation. Sintered bronze powder provides thermal conductivity away from the bearing surface, also serves as a reservoir for the resin mixture.And the POM or PEEK polymer layer provides high wear resistance and low friction even with only minute volume of lubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
Detailed information
Boundary lubrication lead-free bearing is improved on the basis of VSB-20. It has the same performance as the VSB-20, but the surface does not contain lead, and the field of use can be extended to areas with environmental requirements.
