Copper tungsten alloy made whole cylindrical shaft protection sleeve called bushings

Equivalent bush bearing outer ring, the sleeve is integral, and relative to the shaft is in motion, while bearing some fragmentation, relative to the shaft is rotated.
Bush in LEGO Mindstorms series and BioTrans RoSys series robot assembly especially silver Lego standard shaft holder, sub full sleeve 1/2 sleeve two.
Various types of bushings on the major water conservancy generator set, the main material ZQAl9-4, ZQSn10-1, ZQSn6-6-3.
Made whole cylindrical shaft protection sleeve bearing sleeve called the equivalent bearing outer ring, sleeve is integral and is stationary relative to the shaft, and bearing some fragmentation, relative to the shaft is rotated ʱ??
Bearing assembly advised before cleaning with kerosene or diesel clean, dry and oil immersed in oil. Bearing and seat hole assembly, it is necessary to keep the bearing seat hole rotation and axial movement does not occur, to make full contact with the outer surface of the bearing seat hole, the general should ensure that the contact area is greater than 70% or more, in order to facilitate the receiving surface is Machined Copper Tungsten Parts back , steel-on-steel friction coefficient than Copper Tungsten alloy Part large coefficient of friction of plastic, so use with relatively lightweight, both to ensure the use of the seat cover does not move relative to the hole, and not leave the bush so that the outer diameter is too large bush hole large deformation.
Injured equipment likely to cause wear bushings run, resulting in low productivity, accelerated aging equipment, the impact of product quality and a series of hazards, severe cases can cause the device to be forced to shut down or stop the entire production line, resulting in loss of production time, the delay in the delivery shipment dates or even cause serious production safety accidents, equipment due to individual industries bushings wear, production downtime and even forced through the entire production line of all scrapped accidents, resulting in companies forced into bankruptcy overnight.
