What is hollow plain shaft

Composed of shaft body, through-hole, large cylinder, cylinder, small cylinder, internal keyway and external keyway, hollow plain shaft is highly resistant to corrosion and applicable to water, chemical and other environments subject to oxidization.
Hollow shaft has a large space volume, but its weight can be reduced. According to mechanical analysis of material, when torque is transferred by the rotation shaft, its function of effective torque transfer is more significant in the outer segment from the perspective of radial section. For transfer of high torque, larger shaft diameter is required. As the effect of torque transfer is insignificant in the axis part, the hollow structure is adopted to reduce dead load of shaft.
With the guiding function of sliding bearing, LM shaft can be used for linear motion products. The conditions required by these linear motion systems are: simple design, best actuation, low maintenance cost, rough and durable material strictly selected, high-frequency heat treatment, accurate diameter, roundness, verticality and surface treatment.
