Linear Shaft S Inch

Linear Shaft S Inch
ISUTAMI SI linear shaft is an imperial unit precision solid shaft, also known as SI linear round shaft. It has extremely high dimensional stability and long design life. The SI solid shaft is induction hardened and ground, cut to any desired length up to the maximum length of the given diameter. It is then finely polished in order to provide a long lasting round rail positioning system when used with either linear ball bushing bearings or aluminum pillow blocks.

Linear Shaft S Inch Features

SWK stand-up shaft pillow block, SW linear bearing, SSW super linear bearing, SWA linear bearing pillow block, SWB linear bearing pillow block with SI solid linear shaft to be linear positioning systems.

Besides, SI inch solid shaft combined with aluminum shaft support rail, together with SWB-OP open linear bearing pillow block, SWB-L-OP long open linear bearing pillow block, SWD adjustment open linear bearing pillow block, SWD-L long adjustment open linear bearing pillow block and other open series aluminum linear bearing pillow blocks to form linear rail positioning systems.

The choice of ISUTAMI SI linear linear shaft is 45 high quality carbon steel (S45C), surface hardness is above HRC58; GCr bearing steel (SUJ2), surface hardness is above HRC60; 9Cr18 stainless steel (SUS440), surface hardness is above HRC52. The outer diameter (D) of the shaft ranges from 6.35 to 50.8 mm with an accuracy of g6 or L. The depth of the hardened layer ranges from 0.4 to 3.0 mm and the weight per meter ranges from 0.25 to 15.9 Kg/M. (See the table for details)

Technical Description
The shaft is hardened.
Linear bearing and guideway systems for weight reduction.
When selecting the right shaft, the hardness of the shaft, surface finishing and tolerances must be considered, as the balls run directly on the shaft surface.
Modifications, drilling and threaded holes, fixing slots, special coatings, etc. are available.
The shaft length is usually ±2 mm and the ends are not hardened.
