Second, given Gehe weight. Movable weight given Gehe (C) The same group of linear motion systems under the same conditions as each movement to walk 50 kilometers, of which 90% can be achieved can withstand the fatigue phenomenon does not occur is the basic dynamic load given Gehe weight. When the static weight given Gehe (CO) static load, the maximum pressure that is part of the solution then super linear bearings, rotating body and permanent deformation of the track surface and the load of 0.0001 times the diameter of the rotating body when the body, namely basic static set Gehe and severe, given Gehe weight and life expectancy Life expectancy L according to the following formula L: Rated life (KM) fH:. hardness coefficient fT; temperature coefficient fC: contact solution coefficient fW: Load factor P: Working load (Kgf) C :: superiority basic dynamic weight given Gehe (Kgf) flange linear bearing linear bearing in terms of the performance test, due to the different objects bearing used, then the product performance requirements will also change, even for the same type , with a performance of the same size of the bearing. Linear bearing is a straight line in order to reduce the cost of consumption of large parts of linear motion bearings, for limitless cooperation with the cylinder axis travel use. Because carrying the ball point contact with the shaft, so the use of small loads. Minimal friction ball rotation, and can achieve high-precision motion fluctuations. Linear motion bearings _ _ Korea and Taiwan transmission machinery bearings provided by the Dongguan City, Transmission Machinery Co., Ltd. of Korea and Taiwan.
