SF-L1.0023.060-10.000

Product Description:

The SF-L1.0023.060-10.000 is a steel shaft made for the SF Servo Motors by Bosch Rexroth Indramat. This one comes with a diameter of 6 mm and a full length of 10.000 mm. Machined with a ground surface finish, and then hardened using induction treatment — the result is a stable shaft that won’t give under stress. The straightness stays within ±0.01 mm per 100 mm, which makes a big difference when high-speed motor alignment is in play.

Hardness checks in at 60 ±2 HRC, which is on the upper end for motor shafts. That means less wear and fewer replacements. The outer surface is smooth, with a surface roughness of Ra ≤ 0.2 µm — nearly mirror-like when clean. The tolerance class h6 helps keep the fit snug inside precision housings. Roundness stays tight at ≤ 0.001 mm, and the radial runout is also capped at ≤ 0.003 mm, so there’s no annoying wobble or drift during operation. The finish is purely functional — no corrosion resistance is built in, so this part stays indoors or inside sealed enclosures.

There’s no extra plating or anti-rust coating, but the shaft isn’t designed for wet environments anyway. It's best used in dry automation setups where high rotational accuracy matters. In compact servos, especially those running tight tolerances or high RPMs, this shaft handles the load without heating up or losing form. It’s not a flashy component, but the work it does behind the scenes is critical — no play, no slipping, just clean rotation. The SF-L1.0023.060-10.000 works well for robotic joints, CNC platforms, or compact drive assemblies where shaft alignment can’t go off by even a hair. Just solid specs, done right.
