Stainless Steel Parallel Key with Holes
A Stainless Steel Parallel Key with Holes is a precision-engineered component used primarily for securing mechanical components, such as gears or pulleys, to a rotating shaft. It provides a positive drive and alignment by fitting into matching keyways of both the shaft and the connected element. The inclusion of pre-drilled holes serves multiple functional purposes, such as simplifying removal, accommodating alignment pins, or enabling locking mechanisms. This small yet significant component plays a vital role in securing motion transfer and enhancing machinery reliability, especially in high-precision or corrosive environments.
Product Overview
The Stainless Steel Parallel Key with Holes is widely used in mechanical engineering and industrial applications where precision fit, durability, and resistance to corrosion are required. Constructed from high-grade stainless steel (commonly 304 or 316), these keys exhibit excellent performance in tough environments. The parallel design ensures secure torque transmission, while the holes allow for easier key extraction, additional safety locking, or auxiliary pin placement.
