These shaft locking bushes provide maximum torque transfer from a single shaft locking element to another. However, due to their large clamping surfaces, the clamping pressure is controlled to a reasonable level. This design allows for automatic centering between the shaft and hub. And the axial positioning of the hub is not changed during the clamping process. Suitable for applications with high bending loads.

In the case of thin-walled hubs, such as conveyor rollers, the surface pressure on the hub can be reduced by reducing the clamping torque applied to the clamping screws. Reduced to a minimum of 50%; the pressure and torque transferred to the outer hub is reduced proportionally, making the wall thickness up to 12% of the inner diameter usable.

Recca locking bushes have a number of advantages:

• Easy installation – the connection of the hub to the shaft is very simple and only requires a torque wrench.
• Easy disassembly – Easy Requires a simple release by tightening the screw in the jack hole.
• Simplified Manufacturing – Bores hubs in parallel to tolerances of H8 and up to H11 in some sizes.
• Low cost assembly – Eliminates expensive machining of splines, keyways and setscrews.
• Long fatigue life – Eliminates keys, which prevents failure due to rubbing or notching initiated cracks under torsional loads.
• No axial positioning required – Hubs can be placed anywhere on the shaft and locked to withstand high axial loads.
• High torque transmission – Most series will transmit torque equal to the shaft capacity and are a good choice for high torque transmission.Higher torque clamping elements can be combined in one shaft/hub connections.
• Small Diameter Shafts – Eliminating the keyway often allows smaller diameter shafts to be used in many applications.
• Wear free – no moving parts means no wear. Shaft clamping elements can be frequency of tightening and loosening is not subject to wear.
• Less maintenance – when properly assembled, the shaft clamping element requires no maintenance. Self locking action of most designs ensures that the torque is transmitted even when the screw is locked.The screws should vibrate loose during use.
• True operation – Evenly distributed friction locking ensures no backlash and high concentricity.
• Shaft remains unmarked – The shaft clamping element does not leave any markings on the shaft, ensuring easy handling during use.
• Timing of the drive – Simple clamping and releasing allows for stepless angular positioning.
• Overload protection – If the design load is exceeded, the clamping element will slip on the shaft, providing additional protection to other machining components.
• Contamination Resistance – When fully clamped, the contact surfaces are pressed tightly together to prevent contamination.
