Integrated Motor Bracket
Servo motor bracket, also known as motor brackets or motor housings, generally fall into two main categories: one features built-in bearings (integrated motor brackets), and the other combines motor bracket with separate support units (general motor brackets). Integrated type motor bracket maximizes the concentricity between the motor shaft and the screw shaft, eliminating the need for concentricity adjustment and providing a more convenient user experience.
Features
- Structural Rigidity: The housing blank is integrally cast, providing excellent structural rigidity.
- Mounting Accuracy: The integrated type motor bracket adopts precision machining process, ensuring concentric installation of the screw, bearing, coupling, and motor.
- High Reliability: The integrated type motor bracket combines the motor bracket and support unit into a single component, reducing the number of parts in the system and enhancing overall system integration.
- Bearing Configuration: Choose between angular contact bearings or angular contact thrust bearings, typically in DF arrangement.
- The assembly is factory-adjusted for bearing preload and pre-filled with lubricant.
- Surface treatment: Motor brackets are black-oxide treated by default for rust prevention, with other surface treatment options available.

FAQ
If a bearing failure occurs, a repair kit can be ordered for replacement. However, since the bearings and related components require precise installation, we recommend replacing the entire assembly to ensure optimal performance.
Yes. The bearings in the integrated motor brackets are pre-lubricated and properly preloaded. No additional operations are required before use.
Angle A is 30°, angle B is 40°, and angle C is 15°. There is no difference in dimensional usage among them. Although there are slight differences in rated load capacity and maximum operating speed, these do not affect usage. The main difference is that rigidity of the assembled bearing increases significantly with the angle, which has a notable impact on the precision of the bearing housing within the entire ball screw transmission system.
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.
Generally speaking, HZMotion’s motor brackets are divided into A, B, C, H, L, and KK types. The C and KK types feature an integrated structure combining the support unit and motor bracket. The A, B, L, and H types are designed to be used together with FK, FKA, MBK, or WBK support units. Type A, L, and H are suitable for light-load environments, type B is for heavy-load environments, and type KK is for light-load environments. The C type covers the widest range of specifications, suitable for both light- and heavy-load applications.
Temperature affects the accuracy of the bearing.
We add an appropriate amount of grease to the bearings before shipment. The grease replenishment interval varies depending on the operating conditions and environment. Generally, it is recommended to perform maintenance and inspection once every quarter.
