Spare parts

As factory standard, all Dujua equipment items are coupled to the shafts via Tapered Bushings.

Advantages of this system:

• They distribute torque transmission force evenly over 360 degrees of shaft contact. This uniform stress distribution eliminates the wear and maintenance costs associated with key breakage and wear. 
• Assembly on the shaft is simple, just by tightening the screws in the right sequence. No special tools or machining are required to create keys or for maintenance of the shaft slot. 
• Unlike keys, Clamping Elements are completely wear-free, because they work without moving parts in the shaft or hub, reducing component and maintenance costs. Also, as part of the clamping process, application surfaces are subjected to pressure high enough keep contaminants out, again reducing the need for maintenance. 
• They are designed to withstand high torque.
