Precision shafts
Precision linear shafts represent an important category of linear guidance elements. In combination with shaft support blocks, housing units, linear ball bearings, and other accessories, they form a reliable and cost-effective linear motion system.
Linear systems based on precision shafts are widely used in variety of applications where, there is precise linear motion required- from automation and robotics to CNC machines and industrial positioning applications.
Properties
Precision linear shafts represent an important category of linear guidance elements. In combination with shaft support blocks, housing units, linear ball bearings, and other accessories, they form a reliable and cost-effective linear motion system.
Application
Linear systems based on presicion shafts are widely used in any application where precise linear motion is needed. Precision shafts are typically applied in:
Hardness
All of our precision shafts are surface-hardened (induction) up to a depth between 0.4 do 3.2 mm, depending on the shaft diameter. Exact hardening values are listed in the product-specific technical tables.
The hardened layer depth complies with DIN6773
Diameter
The diameter tolerance of precision shafts in accordance with DIN286
| Nominal diameter [mm] | h6 [µm] | h7 [µm] |
| 1-3 | 0 / -6 | 0/ -10 |
| 3-6 | 0 / -8 | 0 / -12 |
| 6-10 | 0 / -9 | 0 / -15 |
| 10-18 | 0 / -11 | 0 / -18 |
| 18-30 | 0 / -13 | 0 / -21 |
| 30-50 | 0 / -16 | 0 /-25 |
| 50-80 | 0 / -19 | 0 / -30 |
| 80-120 | 0 / -22 | 0 / -35 |
