Keyless Bushing – High-Performance Shaft Locking Solution | SUNG-IL MACHINERY

SUNG-IL MACHINERY is a manufacturer specializing in motion control and power transmission components for industrial automation. The company develops high-precision products including couplings, timing pulleys, support units, and A.P. Lock keyless bushings that are widely used in factory automation systems around the world. 

The A.P. Lock keyless bushing developed by Sung-Il provides strong and reliable shaft-hub clamping while maintaining excellent concentricity. Designed for easy installation and efficient performance, these keyless bushings are available in various sizes, materials, and surface treatments to meet the requirements of diverse industrial applications. 

Keyless Bushing:

A keyless bushing, also known as an A.P. Lock, is a power transmission device that locks a hub component directly onto a shaft through frictional clamping. This mechanism eliminates the need for keyways, which are commonly used in traditional shaft-hub connections. By distributing pressure evenly across the contact surface, the keyless bushing ensures precise alignment and stable operation.

Features of Keyless Bushing

High-quality keyless bushings are engineered to provide reliable performance in demanding industrial environments. Key features include:

1. Strong Clamping Force

The keyless bushing uses surface pressure to firmly clamp the shaft and hub, ensuring secure power transmission even in high-load conditions.

2. No Keyway Required

Since it eliminates the need for a keyway, installation becomes easier and machining costs are significantly reduced.

3. Excellent Concentricity

Keyless bushings maintain precise shaft alignment, minimizing vibration and improving the overall efficiency of rotating systems.

4. Easy Installation and Removal

The design allows quick assembly and disassembly, making maintenance faster and more convenient.

5. Corrosion Resistance and Durability

Certain models use advanced materials such as aluminum alloy with surface treatments like anodizing and electroless nickel plating to enhance durability and corrosion resistance. 

If you are looking for a keyless bushing, you can find them at SUNG-IL MACHINERY.

Motor Bracket and Ball Screw Support | SUNG-IL MACHINERY

Image
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 installat...
