Shafts Supporters are used to support the Shafts, which is available in various dimensions.

Crossed Roller is a compact and limited linear motion rolling guide incorporated very accurate cylindrical rollers between V-shaped raceways and it can achieve superior smooth linear motion.

The slide shaft is case hardened and ground steel shafting. Since the linear shaft acts as the inner race of a ball bushing, the specifications such as surface hardness, depth of hardness, surface roughness, cylindricity, and straightness are very important factors for bearing life. The slide shafts are manufactured to required linear motion specifications.

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.
