Pipe Shaft SP

Pipe Shaft SP
ISUTAMI SP pipe shaft is a metric precision hollow one, also known as SP linear hollow shaft. It is lighter in weight and has a higher dimensional stability, longer life than the S solid linear shaft of the same diameter and the same length.

The SP linear pipe shaft is induction hardened and ground and cut to any desired length until the maximum length of the given shaft diameter. It is then finely polished to provide a durable round rail positioning system when used with ISUTAMI linear ball bushing bearings or aluminum housings.

Pipe Shaft SP Features

SP metric hollow shaft commonly assemblies with SK stand-up shaft support, PA stand-up shaft support, SHF horizontal shaft support, Asian metric LM linear bearing series, Asian metric SLM super linear bearing series, European metric KB linear bearing series, European metric SKB super linear bearing series, and matching SMA Asian metric linear bearing pillow block, KBA European metric linear bearing pillow block

Also SP metric pipe shaft is combined with aluminum shaft support rail, with SME Asian metric open linear bearing pillow block, SME-L Asian metric long open linear bearing pillow block, TBR Asian metric adjustment open linear bearing pillow block, KBE European open linear bearing pillow block, KBB-OP European metric open linear housings to form a linear rail positioning system.

The conventional material of ISUTAMI SP hollow linear shaft is GCr bearing steel (SUJ2) with hardness above HRC60 to ensure sufficient strength and hardness in the application. The outer diameter (D) of the shaft ranges from 16 to 50 mm, and the inner diameter (d) ranges from 7.5 to 36 mm. The accuracy is g6 or h6, the depth of the hardened layer ranges from 0.6 to 2.0 mm, and the weight per meter ranges from 1.23 to 7.42 Kg/M. (See the table for details)

Tips:
Modifications, drilled and tapped holes, retainer grooves, special coatings etc. are available.
Shaft lengths are cut to typically ±2mm, ends are not hardened.
