Movement applications using bearings can be found in every industry: slow and fast applications, light and heavy applications, abrasive and clean applications. Every industry has its own preference for a bearing type, for example sliding bearings, and every application in turn has its preference for specific variants such as a POM sliding bearing. Viiplus Industrie are dealers for very high quality POM sliding bearings.

Technical information and standard dimensions on the data sheet.

The most important properties of  dry bearings are:

Sliding surface made from POM with a steel outer jacket
Bearings with a minimum of lubrication for grease-lubricated applications
Maintenance-free operation
Little wear
Best performance at relatively high loads and low speeds

Structures

1. POM thickness 0.30~0.50 mm, it 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.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the resin mixture.
3. Low-carbon steel, provides exceptionally high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.
