Schaeffler KUE25-B-EC INA KUE series ball screw Ball monorail guidance system

KUE25-B-EC: "EC" may represent a combination of specific accuracy grades and sealing forms. It has good dustproof and sealing performance, can work stably in some dusty environments or environments with high requirements for screw protection, while maintaining high accuracy, and is suitable for industries such as textile machinery and woodworking machinery.

Dimension parameters:

Nominal diameter: 25mm, which is the main dimension indicator of the ball screw, and determines its basic characteristics such as load capacity and installation space.

Lead: There may be multiple options, such as 5mm, 10mm, 20mm, etc. The lead determines the axial movement distance of the nut for each rotation of the screw. Smaller leads are used for high resolution and precise position control, while larger leads can provide higher linear speeds.

Load capacity:

Dynamic rated load: As a member of the KUE25 series, it can withstand certain axial and radial loads to meet medium-scale load requirements. The specific value needs to be referred to the Schaeffler product manual, which 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 when stationary or at low speed. The specific value also needs to be referred to the product manual.

Accuracy level: Schaeffler ball screws usually have multiple accuracy levels, such as CT0 - CT5, etc. KUE25-B-EC may provide products of different accuracy levels. The products used for precision machining equipment may be CT3 or higher, and the products used for general automated production lines may be CT5. The higher the accuracy level, the smaller the axial and radial tolerances per revolution, and the higher the positioning accuracy and repeatability.

Speed characteristics:

Maximum speed: Limited by multiple factors such as the screw structure, lubrication method, load size, and drive system, it can adapt to a certain range of working speeds to meet the operating requirements of different equipment under the premise of meeting the load and accuracy requirements. 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, KUE25-B-EC may be equipped with corresponding sealing devices, such as sealing rings, dust covers, etc.
