Standard Support End
The support end support units are designed to accommodate a wide range of application scenarios and are typically used in conjunction with general fixed end support units. You can select the most suitable product and configuration based on your specific application needs.
Features
- Bearing Configuration: Equipped with imported precision deep groove ball bearings.
- Surface treatment: The bearing housing is black-oxide treated by default for rust prevention, with other surface treatment options available.

FAQ
Square-structured ball screw support units are suitable for various installation space configurations and are especially ideal for applications where operation passes through shoulder spaces. Among square bearing housings, types such as AK, BK, and LK are classified as light-duty and are typically used as fixed ends in automation equipment or machinery with light loads. Types like AF, BF, and EF are commonly used as support ends. BK-TAC, EK-TAC, SBK, and SBK-U are classified as heavy-duty and are used as fixed ends in machine tools or heavy-load applications.
Lubrication, locking condition and installation status should be checked according to actual working conditions to avoid abnormal loads affecting service life.
Round-structured ball screw support units are typically used in combination with A-type, B-type, H-type, or L-type motor brackets. Light-duty support units are usually equipped with 30° angular contact ball bearings, while heavy-duty support units are fitted with 60° angular contact thrust ball bearings specifically designed for ball screws. Support-end support units are generally equipped with deep groove ball bearings. Heavy-duty support units are often used in a double-ended tension configuration.
The flange outer diameter of a round type support unit is a non-mating surface and is not strictly controlled for geometric tolerance; it only needs to meet the national standard tolerance values. The root of the flange, which is the outer cylindrical surface of the bearing housing, is the mounting mating surface and is subject to strict geometric tolerance requirements.
Under normal use, the support unit is not easily damaged. For support units assembled with standard ball screws, the support unit’s load capacity matches that of the installed ball screw. The actual service life is closely related to the operating environment, load magnitude, lubrication and maintenance, and usage frequency.
Temperature affects the accuracy of the bearing.
