Triple row roller slewing bearing

Flange bearings from printers, fax machines to monitor, using household items in their daily lives, there my company's products bearing the bearing show technology space.ABEC-1 in standard dimensions and accuracy requirements, produce bearings, which can meet the general use of the product.
Outer flange on the series, is the axial position is simple: no longer need housing, Taper roller bearings more cost effective.To get bearings low-friction torsional Rotary precision, high rigidity and good the Cabinet, using small-diameter steel balls.The use of hollow shaft, to ensure that the light-weight and wiring space.Main use: Robotics, medical devices.Office equipment.Medical instruments.Slow speed device.Motor.Optical imaging devices. taper roller bearing The card reader.

Thin section bearings

High speed bearing installation and adjustment:
1. high speed bearing fit and clearance due to the high speed bearings according to requirements of high precision bearings, and required by the high temperature bearings, so when considering the fit and clearance, to take into consideration the following two points:
(1) rose from room temperature to high temperature dimensional change and hardness changes;
(2) high-speed centrifugal force caused by the force of change and shape change.
In short, in conditions of Slewing drives, high temperature, from coordination and clearance on the choice to try to keep the accuracy and performance of the bearing, which is difficult.
In order to ensure that after installation of bearing Raceway deformation is small, KOYO 7319AC angular contact ball bearings fit interference cannot be made too large, of centrifugal force and high speed and high temperature thermal expansion, or offset the mating surfaces of the normal pressure.Or Flange Slewing Bearing relaxing the mating surfaces, interference must therefore consider the premise of these two factors carefully calculated effective interference at room temperature under normal speed for high precision bearings may be invalid.

Exponentially growing of wind power installed capacity

From the current wind power bearing development situation, the wind power installed capacity will grow exponentially, the planning objectives will be greatly exceeded. 2007 is estimated to reach 5 million kilowatts, eleven five to three years ahead of the target planning.

  Experts predict that by 2020 will reach 120,000,000 kilowatts,crane bearing ， an average annual increase of 10 million kW .

Development strategy according to the China energy today, the state will greatly improve the wind energy（ wind power bearing ）, solar energy, biomass and other renewable energy in the whole energy consumption.

  The proportion of. In this strategy under the guidance of this year, to Chinese wind power industry development quickly.

  According to the Chinese renewable energy and long-term development plan put forward the development of wind power target,metallurgical bearing

• In 2010 the national wind power installed capacity has reached 5 kilowatts million
• In 2015 the national wind power installed capacity has reached 15 kilowatts million
• In 2020 the national wind power installed capacity reached 30 kilowatts million
