1

Support Unit Surface Rust

Surface treatments only provide a limited duration of protection. During use, the surface should be continuously maintained with an oil film or kept in an environment that offers protection. For long-term storage, the product should be placed in a dry area. If there are special usage requirements, please consult with your sales representative.

2

High Operating Resistance

Check if the retaining ring on the shaft end face is missing, which could cause the bearing housing seal to rub against the screw shaft.

3

Abnormal Friction Noise During Operation

Try applying an appropriate amount of grease to the sealing lip of the seal.

4

Whistling Noise During Operation

Check whether cutting fluid has entered the bearing housing, causing lubrication failure.

5

Fixed End Support Unit Overheating

Check for overload, whether the seal interferes with the retaining ring or the screw shaft shoulder, and whether the screw and guide rail are parallel.

6

Poor Axial Positioning Accuracy

Check whether the runout of the screw shaft shoulder meets the requirements, ensure that the shoulder and shaft diameter areas are properly chamfered, verify if there is any axial clearance in the bearing housing, inspect for axial play in the screw assembly, and confirm that the control system’s precision meets specifications.
