we can offer linear shaft with diameter5mm-150mm,maximum length up to 6000mm.
when you have special requirements on length, we can meet your machining requirement with different length, such as when you request above 6000mm,we can anti-connect for you .

The SBR Aluminum Linear Block consists of the aluminum housing, outer race, steel ball, ball retainer, retainer ring, iron sheet, etc. The balls can be maintained within the loop by the retainer, which is fixed into the outer race through the retaining ring. In addition, the bearing can be fixed in the aluminum case by the iron sheet. An additional dust shield is also available.

Double Nut Ball Screw assembles two inner-circulate nuts together, therefore reduces the backlash of ball screw. The stability is then enhanced and the accuracy is up to 5. This design is special for CNC machine centers.

1.Chrome plated for corrosion resistance;
2.Case hardened for wear resistance;
3.Precision ground for consistent ball bushing radial clearance;
4.Shaft diameter and length specified for accurate fit;
5.Round steel shaft for use with linear support blocks and closed type slide units in linear motion applications.

​1.Rail shaft diameters from 10mm to 50 mm;
2.Rail lengths to 6000 mm;
3.Carriage speeds up to 0.457 m/s;

Linear motion is a one dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension. The linear motion can be of two types: uniform linear motion with constant velocity or zero acceleration; non uniform linear motion with variable velocity or non-zero acceleration. The motion of a particle (a point-like object) along a line can be described by its position. An example of linear motion is an athlete running 100m along a straight track.
