1). Production Features of  Z9 Shaft Locking Assembly 

a)      High transmission capacity: locking pressure is uniformly distributed over a large area around a shaft circumference and inside hub, enabling it translates high torque and shock loads more consistently than on that relies on a key.

b)      Good protection for shaft and hub: locking assembly lessens stress concentration, and the strength of shaft and hub are improved without keyways. They are well protected at the same time.

c)       Easy installation and good interchangeability: locking assembly prevents problems associated with keyed devices such as shaft play, slippage, backlash, and position misalignments.

d)       Reliable and stable performance: It provides reliable for applications involving high torque or sudden starts and stops.

e)       High quality and Competitive Price: BASKA will provide high-quality locking assemblies with a perfect price, and cost-effective solutions for our clients.  

2). Applications of Z9 Shaft Locking Assembly 

         Locking assemblies are widely applied in many industries including heavy-duty machinery, wind power, mining machinery, metallurgical machinery, and other equipments.
