Transport ball screws

Transport ball screws

Transport ball screws are used in applications where high accuracy of positioning is not required, such as for example in transporting and lifting devices, wood processing machines, etc.

The screw shaft is produced by rolling or whirling and the shaft ends are machined according to the request of the customer. They are equipped as a standard with an APE type of nut, which is a single non-preloaded nut with flange. These ball screws are produced in the T5 and T7 precision classes. Their main advantage is a lower price.

Characteristics:

Productive and quick production of the screw
Non-preloaded nut with backlash 0.015–0.05 mm (depending on the ball screw size)
Standard geometric and working accuracy according to DIN ISO 3408 for transport ball screws

Technical parameters:

Diameters from 12 to 63 mm – rolled, from 32 to 100 mm – whirled
Recommended pitch up to 10 mm – rolled and up to 30 mm – whirled
Precision class T5, T7
Do×n = 80,000, efficiency 93–95 % (according to thread pitch and lubricant)
Minimum strength of the shaft material Rm = 650MPa, functional surfaces of the shaft and nut hardened to 58-60HRC
Working temperature -20 to +60°C

Applications:

Transporting mechanisms
Wood processing machines
Substitution of racks
Long actuation assemblies

Example of designation: K63x10 – 4/APE TS (ball screws with diameter 63 mm and pitch 10 mm, 4 working threads of the APE single nut with flange, transport design, the standard type 3 of the flange is not pointed out).
