At SUNG-IL MACHINERY CO., LTD., the motor bracket and ball screw support unit plays a critical role in precise linear motion systems. This supporting assembly ensures stable, accurate transmission between a motor and a ball screw, handling axial and radial loads while maintaining alignment and performance.

What Is a Motor Bracket and Ball Screw Support Unit?
 It is a combined unit that provides shaft-end support for the ball screw, integrating the motor bracket (fixture part) with a bearing support (support side).
 The fixture part typically uses angular contact ball bearings in a preloaded duplex arrangement to achieve rigidity and minimal torque.
 The support part often uses a deep-groove (radial) bearing design to carry radial and light axial loads.
 The unit includes dust seals or oil seals to keep out contamination and retain lubrication for long-term reliability.
By combining the motor bracket and support into a single standardized unit, the system simplifies installation, maintains high precision, and ensures repeatable alignment.

Key Features and Advantages:
1. Design Simplicity and Standardization:
The units are manufactured in standardized dimensions, reducing the need for adjustments or custom machining during assembly.
2. High Precision and Minimal Assembly Error:
Preloaded angular bearings and face-to-face duplex mounting minimize alignment errors and maintain rotational precision.
3. Dust and Contamination Protection:
Seals are integrated to prevent dust ingress and grease leakage, enhancing reliability in harsh or industrial environments.
4. Interchangeability and Flexibility:
Because the units are modular and standardized, different series types can be interchanged to suit layout or load changes without redesigning the entire system.
5. Enhanced Lubrication Options:
Some series include grease-injection capability for easier maintenance and lubrication management.
