Self-lubricating Bearings made to order from china ,VIIPLUS In the field of renewable energy Tribology solution
-High precision composite PTFE, POM bearing inner and outer diameter can be machined to obtain excellent application accuracy, roundness and cylindrical tolerance
-The high precision pre-machined bearings are available for immediate installation
-High precision can be obtained in the field by convenient single point machining of bearing sliding layer before installation
-After installation, the bearing sliding layer can be conveniently processed at a single point to obtain high precision and high load capacity
-Excellent impact and edge load resistance
-Low friction, slippage can be ignored
-Low wear rate can extend bearing life
-Excellent corrosion resistance of carbon steel or stainless steel 316
-Size stability - low water absorption, low expansion
Facing the high temperature, what else can we do but make fun of ourselves?The data offer some new clues:
·Whether global temperatures rise by less than 1.5 ° c above pre-industrial levels between 2030 and 2052 will be a matter of life and death for the planet's ecosystems and many people.
·The most important way to achieve these goals is to achieve them globally:
·The share of electricity generated by hydropower, solar and wind power increased from 20% to 70%.
·The proportion of coal power decreased from 40% to 10%!
Countries around the world are taking action:
·The Spanish power group plans to shut down all coal-fired power plants by 2020;
·France plans to close all its coal-fired power stations by 2021;
·Britain's decision to close all its coal-fired power stations by 2025;
·The Netherlands will ban the use of coal to generate electricity from 2030.
·Finland plans to ban coal altogether by 2030;
·Germany has announced that it will scrap coal altogether by 2038;
ITOCHU, a Japanese trading company, issued a statement on February 14, 2019, promising not to participate in the development of any new coal-fired power generation and coal mine projects, and at the same time to conduct a strict assessment of the company's existing coal assets and gradually withdraw.
But when coal power gradually out of the historical stage, whether new energy generation and undertake heavy responsibilities?
Hydropower is facing a series of challenges such as high stability, high reliability and maintenance-free
Solar power generation and wind power generation also face problems such as maintenance free and extended life under bad working conditions
The share of electricity generated by hydropower, solar and wind power increased from 20% to 70%.
The proportion of coal power decreased from 40% to 10%!
1. Self-lub. Layer PTFE Mixture 0.01-0.03mm. After rolling process completed, PTFE mixtures are filled in intersice of bronze layer. Under normal operation, Part of PTFE mixture on top layer will be removed and transferred on the mating surface, forms a physically lubricating film, which will reduced the firction coe. and protect the mating shaft.
2. Porous Bronze layer; The layer provides bonded strength of Self-Lub. Layer.
3. Steel Backing The layer provides load & thermal conductivity
4. Copper / Tin layer

VIIPLUS BUSHINGS is a dry sliding bearing with PTFE sliding layer. Lubrication is therefore not necessary, but basically possible!
Special dimensions are available on request
*If you like to use lubrication nonetheless, please remember to lubricate the sliding bearing regularly.
