Specification

Description

The XB D20L25 is a precision-engineered aluminum flexible spider shaft jaw coupling designed to connect shafts with varying diameters. With an outer diameter of 20mm and a length of 25mm, this coupling is ideal for applications requiring a compact and durable solution for power transmission. The coupling features a flexible spider insert made of elastomer material, which provides excellent shock absorption, vibration damping, and compensation for minor misalignments between connected shafts. The coupling is constructed from high-strength aluminum alloy, ensuring durability and resistance to corrosion while keeping the overall weight low. It accommodates bore sizes ranging from 3mm to 10mm, making it versatile for different shaft diameters. The 2 M3 set screws ensure a secure connection to the shafts, allowing for easy installation and maintenance. This coupling is suitable for use in various applications such as CNC machines, 3D printers, robotics, and industrial automation systems. Its ability to handle misalignments and reduce backlash makes it a valuable component for high-precision and high-performance environments.

Features:

High-Quality Material: Aluminum alloy construction for lightweight and corrosion resistance.

Flexible Spider Insert: Elastomer material absorbs shocks, reduces vibrations, and compensates for misalignments.

Precision Engineering: Designed to minimize backlash and ensure smooth torque transmission.

Versatile Bore Sizes: Inner hole diameters from 3mm to 10mm to fit different shafts.

Secure Installation: 2 M3 set screws for a reliable connection to shafts.

Temperature Tolerance: Operates effectively in a wide temperature range from -40°C to 80°C.

Applications:

CNC Machines: Connects stepper or servo motors to lead screws or other drive components.

3D Printers: Ensures accurate and smooth movement of print heads and other moving parts.

Robotics: Used in robotic arms and joints where flexibility and precision are essential.

Industrial Automation: Suitable for machinery and equipment requiring reliable power transmission and alignment compensation.

Advantages:

Compact and Lightweight: Ideal for applications with space and weight constraints.

Effective Misalignment Compensation: Reduces wear and tear on connected components by accommodating small misalignments.

Smooth Operation: Minimizes backlash and vibration for precise control and reliable performance.

Durable and Corrosion-Resistant: Aluminum construction ensures long-term durability and resistance to environmental factors.

Disadvantages:

Limited Torque Capacity: Not suitable for applications requiring high torque levels.

Wear on Elastomer Insert: The flexible spider may wear out over time and need replacement.

Size Constraints: The compact design may not fit all applications, especially those requiring larger couplings.
