Schaeffler KUE40 Ball Screw INA KUE series Ball monorail guidance system

KUE40: The nominal diameter is 40mm, which is often used in large mechanical equipment or occasions with extremely high requirements for accuracy and stability, such as the worktable moving mechanism of a large gantry milling machine. It can withstand heavy loads and achieve high-precision linear motion to ensure machining accuracy and stability

The technical parameters of Schaeffler KUE40 ball screw are usually as follows:

Dimensional parameters

Nominal diameter: 40mm, which determines the basic characteristics of the screw such as load capacity and installation space.

Lead: Common ones may be 5mm, 10mm, 20mm, etc. The lead determines the axial movement distance of the nut for each rotation of the screw.

Load capacity

Dynamic rated load: The specific value needs to refer to the Schaeffler product manual. It can generally meet the medium-sized load requirements, and it is estimated to be between thousands of Newtons and tens of thousands of Newtons.

Static rated load: Usually higher than the dynamic rated load, it can ensure that it can withstand large external forces at rest or at low speed. The specific value is in the product manual.

Accuracy level

Schaeffler ball screw accuracy levels are usually CT0-CT5, etc. KUE40 may provide products of different accuracy levels. The accuracy for precision machining equipment may be CT3 or higher, and the accuracy for general automated production lines may be CT5. The higher the accuracy level, the smaller the axial and radial tolerances per turn, and the higher the positioning accuracy and repeatability.

Speed characteristics

The maximum speed is limited by many factors such as the screw structure, lubrication method, load size and drive system. Under the premise of meeting the load and accuracy requirements, it can adapt to a certain range of working speeds to meet the operation requirements of different equipment. Its DN value (the product of the nominal diameter and the rated speed) can be used as a reference indicator to evaluate the performance of the screw at high speed.

Lubrication and sealing

Lubrication method: Common ones are grease lubrication and oil lubrication. Schaeffler will provide corresponding lubrication solutions according to specific application scenarios and customer needs to ensure the normal operation and service life of the ball screw.

Sealing form: In order to prevent dust, impurities, etc. from entering the screw pair and affecting performance and life, KUE40 may be equipped with corresponding sealing devices, such as sealing rings, dust covers, etc.
