Product Description

 

 

Boundary Lubricating Bearings Black POM Bushes lead-free | VSB-20

 

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

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.

Structure Characteristics
 

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.

CHARACTERISTICS



VSB-20 Boundary lubrication bearing High Quality DX Bushing POM Bush China Manufacturer
· marginally lubricated bushings for grease or oil lubricated applications
· Standard parts contain grease indents in the sliding layer; plain sliding layer available by request
· Optimum performance under relatively high loads and low speeds
· Suitable for linear, oscillating and rotating movements
· Wide range of parts available from stock
 
Suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.

STRUSTURE

1. POM thickness 0.30~0.50 mm. It provides high wearresistance and low friction even with only minute volume oflubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
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.Setting the foundation of the bushings, the steel back provides exceptional stability,load carrying and heat dissipation characteristics.
