Z4 Keyless Locking Device Locking Elements Clamping Assembly
Products Features
Locking Assembly is an advanced mechanical base that is widely used in the world
for mechanical coupling under various loads. The United States, Germany, Japan
and countries with more developed industries first used this new technology in
heavy-duty machinery. It has been extended to various other machinery industries.
Locking Assembly started internationally in the early 1970s. China developed the
product in the early 1980s, and firstly promoted and applied it in various heavy machinery.
In the past six years, China has formulated the general Locking Assembly
GB5867-86 standard. Our company Tianniu started the comprehensive research and
development of various expansion sleeves of this standard in 1987. After nearly 20
years of practice, we have completed the development of all types of expansion
sleeves in this standard. And promoted to textile, packaging, food, light industry,
metallurgy, papermaking, printing, machine tools, machining centers, forging machine
tools, and metallurgical machinery and general machinery and other machinery,
took a good reputation, and promoted the machinery industry products. skill improved.
And can develop non-standard Locking Assembly according to special user needs
