Hex & D bore shaft collars are used to secure rotating shafts in machines and other equipment. Both hex bore and D-bore shaft collars are designed to prevent shafts from wobbling or vibrating. They do this by applying pressure to the shaft, which helps to keep it centered and in alignment. This is important for the smooth operation of machines and other equipment.

Hex bore and D-bore shaft collars are available in a variety of sizes and materials. They are typically made from steel, stainless steel, or aluminum. The material used will depend on the application and the environment in which the collar will be used. Both hex and D bore shaft collars are commonly used in a variety of industrial and mechanical applications, including in machinery, conveyor systems, and robotics.

Hex & D Bore Shaft Collar

Hex & D bore shaft collars are types of mechanical components used to secure a shaft or rod in place. They are typically made of steel, aluminum, or stainless steel and consist of a cylindrical ring with a set screw or other fastening mechanism to grip the shaft.

A hex bore shaft collar has a hexagonal-shaped hole in the center, allowing it to be easily tightened or loosened with a hex wrench. These types of shaft collars are often used in applications where frequent adjustments or removals of the collar are necessary.

A D bore shaft collar has a D-shaped hole in the center, which provides a tight grip on the shaft and prevents it from rotating. These types of collars are often used in applications where precise alignment is required, such as in robotics or automation systems.

Both hex and D bore shaft collars are commonly used in a variety of industrial and mechanical applications, including in machinery, conveyor systems, and robotics. They are often used in conjunction with other components, such as bearings or pulleys, to provide secure and reliable shaft support.

▍Best Hex & D Bore Shaft Collars for Sale

We manufacture standard shaft collars with hex and d bore profiles for proper mating with the appropriate shaft. Hex bore shaft collars allow for added holding power and higher torque capabilities if being used in positive drive applications. D bore shaft collars are designed for use with d-shafting. They are a better option than set screw shaft collars as they do not mar the shaft, have higher holding power, and are indefinitely adjustable.

HZPT manufactures hex and D bore shaft collars in 1215 lead-free steel with a proprietary black oxide finish and 303 stainless steel. Hex shaft collars are also available in high-strength 2024 aluminum for lightweight applications. D bore shaft collars available in bore sizes from 1/4″ to 1″ and hex bore collars from 3/8″ to 1/2″.

▍Benefits of Using the Hex & D Bore Shaft Collars

Hex & D bore shaft collars are a type of shaft collar that is designed to fit hex or D-shaped shafts. They offer a number of benefits over other types of shaft collars, including:

1. Increased holding power: Hex and D bore shaft collars have a larger surface area that comes into contact with the shaft, which results in increased holding power. This is important in applications where the shaft is subject to high torque or vibration.

2. More even surface contact: The larger surface area of hex and D bore shaft collars also results in more even surface contact with the shaft. This helps to distribute the load more evenly, which can help to prevent premature wear and tear on the shaft and collar.

3. No marring of the shaft: Hex and D bore shaft collars do not use set screws, which can mar the shaft. This is important in applications where the shaft is made of a soft material, such as aluminum or brass.

4. Indefinite adjustability: Hex and D bore shaft collars can be adjusted indefinitely, which makes them ideal for applications where the load or torque requirements may change over time.

▍Hex Bore Shaft Collars and D Bore Shaft Collars

Hex bore shaft collars and D bore shaft collars are both types of shaft collars that are used to secure components to a rotating shaft. They are both made of two pieces that are clamped together to create a tight fit around the shaft. However, there are some key differences between the two types of shaft collars.

Hex bore shaft collars have a hexagonal bore that fits over a hexagonal shaft. They are typically made of steel or stainless steel and are available in a variety of sizes. Hex bore shaft collars are more versatile than D bore shaft collars and can be used with a wider range of shafts. They are also more resistant to vibration and shock.

D bore shaft collars have a D-shaped bore that fits over a D-shaped shaft. They are typically made of aluminum or plastic and are available in a smaller range of sizes than hex bore shaft collars. D bore shaft collars are less expensive than hex bore shaft collars and are easier to install. However, they are not as resistant to vibration and shock as hex bore shaft collars.

Which type of shaft collar is right for you? The best type of shaft collar for you will depend on the specific application. If you need a shaft collar that is versatile, resistant to vibration and shock, and available in a wide range of sizes, then a hex bore shaft collar is the best option. If you need a shaft collar that is less expensive, easier to install, and available in a smaller range of sizes, then a D-bore shaft collar is the best option.

Here is a table that summarizes the key differences between hex bore and D bore shaft collars:

Feature Hex Bore Shaft Collars D Bore Shaft Collars
Bore shape Hexagonal D-shaped
Material Steel, stainless steel Aluminum, plastic
Size range Wide Limited
Cost More expensive Less expensive
Installation More difficult Easier
Vibration and shock resistance More resistant Less resistant
