• Wide range of types and sizes available
• Suitable for many applications
• Compensates for misalignments: Keyed sleeves can absorb some amount of misalignment, extending the life of components and improving system reliability.
• Protects components against overloads: In case of overload, keyed sleeves can slip, protecting other system components from damage.
• Facilitates installation and maintenance: Keyed sleeves are relatively easy to install and dismantle, easing hydraulic system maintenance.

Keyed coupler : Installation and Dismantling Guide

Before starting the installation or dismantling of a keyed coupling sleeve, ensure you have the appropriate tools and equipment and follow safety guidelines. Thoroughly clean the contact surfaces of the shafts and the keyed sleeve to avoid contamination and use suitable lubrication on the keyways of the keyed sleeve and shafts to facilitate installation and dismantling.

Installation :

• Shaft Preparation: Ensure shafts are clean, dry, and free of damage. Ensure keyways match those of the keyed sleeve.
• Keyed Sleeve Mounting: Slide the keyed sleeve onto one of the shafts until it reaches its final position. Carefully align the keyways of the sleeve with the shaft's keyways.
• Key Insertion: Insert the key into the keyway of the keyed shaft adapter sleeve and into the corresponding keyway of the other shaft. Ensure the key is correctly aligned and fits snugly into the keyways.
• Tightening the Keyed Sleeve: Use nuts and washers to secure the keyed sleeve to the shaft. Tighten the nuts evenly and gradually until the keyed sleeve is securely fixed.
• Final Check: Verify that the keyed coupler is correctly installed and aligned. Ensure there is no excessive play between the sleeve and the shafts.

Dismantling :

• Loosening the keyed shaft adapter sleeve : Loosen the nuts and washers securing the keyed sleeve to the shaft. Do not completely remove the nuts and washers at this moment.
• Key Removal: Take out the key from the keyed shaft sleeve's keyway and from the keyway of the other shaft.
• keyed sleeve bushing Dismantling: Slide the Keyed coupler off the shaft. Be careful not to damage the grooves of the sleeve or the shaft.
• Cleaning: Thoroughly clean the contact surfaces of the shafts and the keyed sleeve to remove any dirt or debris.

Keyed shaft sleeve : Differences from Splined Sleeves

The terms "splined sleeve" and "keyed shaft sleeve" refer to two types of mechanical fittings used in different contexts, particularly in engineering and mechanics. Here are the general differences between the two:

Splined Sleeve :

• Features grooves or splines along its surface, inside or outside, or sometimes both sides.
• Used to ensure a robust and axial connection between two components, typically in power transmission systems, such as splined shafts, wheels, or splined gears.
• Commonly used in mechanical transmissions, hydraulic couplings, and other systems where precise connection and efficient power transmission are essential.

Keyed coupler :

• Equipped with a notch or housing designed to receive a key.
• Used to secure two rotating elements, such as a shaft and a hub, so they rotate together and transmit rotational torque.
• Frequently found in mechanical assemblies requiring precise power transmission, such as drive shafts, gears, and similar components.

In summary, the main distinction lies in the design of the fittings and how they ensure the connection between mechanical components. Splined sleeves use splines for this connection, while keyed sleeves incorporate a key to ensure a solid coupling.

Keyed sleeve bushing : Application Areas

Keyed shaft adapter sleeves are versatile components used in a wide range of industrial and mechanical applications. Here are some examples of areas where keyed shaft adapter sleeves are used:

Hydraulic :

• Power transmission between shafts
• Hydraulic pumps
• Hydraulic motors
• Hydraulic reducers
• Hydraulic distributors
