Product Feature of Machine Keys

Machine Keys, is a key that relies on two side surfaces as working surfaces and transfers torque by pressing the sides of the key and the keyway.
Machine Keys are divided into three types: standard machine keys, thin machine keys, guiding machine keys.
Standard machine keys have good centering, high positioning accuracy and easy assembly, but they cannot achieve axial fixation of parts on the shaft. They are used for shafts that are high-speed or subjected to impact and variable loads;
Thin machine keys are used for thin-walled structures and places where the transmission torque is small; guiding machine keys are used to fix the keys on the shaft with screws, and are used for occasions where the parts on the shaft donot move much along the shaft.

Frequently asked question (FAQ)

Question: What kinds of materials do parallel keys generally have?
Answer: There are two materials: steel and stainless steel.
Question: How to distinguish the use of parallel keys according to the different shapes?
Answer: Choose different shapes to use, depending on the keyway shape and position.
Question: What do I need to pay attention to when using parallel keys?
Answer: When the fit clearance is too large, it is easy to loosen and cannot be completely fixed, and when it is too tight, it may be unable to install.
Question: What is the effect of removing threaded hole on the parallel key?
Answer: It can facilitate disassembly and reuse without damaging the shaft and keyway.
