• High - Precison ground and hardened (HrC60) shafts
• Shafts exclusively used for linear motion ball bearings
• Pipe shafts for lightweight uses
• Standard shafts which are quickly delivered at reasonable price
• Available in max length of 2000 mm (can be cut to your requirement)



Technical Details

• SUJ-2 material is used
• The surface hardness is around HRC 58-63
• High frequency induction hardening is used The standard hardening depth is 1-2 mm
• Surface roughness is 1.5 S. or less
• The shafts outside diameter is normally set to keep a tolerance of about a 10 um clearance between itself and the linear motion ball bearing if a stricter to tolerance is needed, Ozak also manufactures shafts having close outer diameter tolerances (For instance h5 h6 types)

• Pipe shafts are recommended if you are aiming for lightweight machinery or need big diameter shafts About a 40 to 50% weight reduction is possible compared with solid shafts


OZAK has been engaged in the manufacture of specialty high-precision ground and Hardened shafts for linear motion ball bearings for a long time. Their production Requires many different manufacturing processes and the use of advanced technology. In fields like material selection heat treatment strain elimination and the all around precision machining. Since the shafts must be manufactured to match the inner race of the linear motion ball bearing care must be given in the following areas to achieve. High performance, hardness and surface roughness.
