UNS2020
20 mm shaft / 35 mm outer diameter. Data source: UVT Catalog 2024. The approved drawing governs ordering.
Dimensional & Load Reference
| Shaft diameter d | 20 mm |
|---|---|
| Outer diameter D | 35 mm |
| Catalog dynamic load C | 8900 N |
| Catalog static load C₀ | 16300 N |
| Dynamic / static torque | On request |
| Shaft lengths / travel | Reference lengths: 500 / 700 / 1500 mm; confirm length for your stroke |
| Nut length & mounting dimensions | See the configuration drawing |
| Load direction & rating conditions | Confirmed for your load case |
| Accuracy & preload | Series-specific suffix codes |

Screw, spline and support-bearing ratings must be checked separately. Load ratings alone do not confirm life, speed or installation suitability.
Selection Guides & CAD Requests
English PDF guides are general references, not configuration-specific CAD. Request 2D / 3D drawings for your model, shaft length and suffixes.
Request This Exact Configuration →Required Operating Conditions
Shaft and housing envelope, nut retention / flange dimensions, shaft length, travel, radial load and load direction, torque, speed, duty cycle, accuracy, preload and lubricant/environment.
Specify the Complete Assembly
Select screw/spline shaft diameter and lead, shaft length, nut arrangement, end machining and separate screw/spline accuracy codes. Confirm all suffixes against the UBNS/UNS drawing.
UNS Operating Precautions
Check alignment and mounting datums, spline/screw engagement and support-bearing loads. Obtain the series-specific lubrication and maintenance specification.
Cleanroom, vacuum, corrosion and special lubricants require individual review.
