Parallel shaft keys explained
Parallel keys are a critical component used to efficiently convey shaft rotation to gears. These items are used in machine tools, automobiles, construction equipment, food machinery, pumps, and more. Parallel shaft keys come in different names depending on the vendor and industry in which they are used. They are variously referred to as parallel shaft keys, machine keys, and shaft keys, but these all refer to the same product.
These items are used in machine tools, automobiles, construction equipment, food machinery, pumps, and more.
JIS B1301 standard
Key sizes are standardized under JIS. In 1972, the JIS standards were amended, producing major differences in terms of dimensions and tolerance thresholds. This has led to the use of an “old” and “new” set of JIS standards.
The JIS standards define steel parallel shaft keys, sloped/inclined keys, crescent keys, and the keyways for these to be made in B1301.
We maintain a permanent inventory of 10,000 JIS-compliant parallel shaft keys.
The JIS standards call for a tensile strength of 600N/m㎡ or greater. Some clients, however, require heat treatment, carbide materials, or materials that are difficult to machine as a way of achieving greater resilience, and we are equipped to accommodate these materials.
