Prism Key 8x7x22 A - Steel Parallel Key for Shaft-Hub Connection

Industrial Applications and Use Cases

Main Description

The Prism Key 8x7x22 A is a standardized steel machine element used to create a secure mechanical connection between a shaft and a hub. Its purpose is to transmit torque, ensure correct alignment and prevent rotational slippage in drive systems. The “A” designation refers to DIN 6885 A, which defines a full-profile, rounded key with precise tolerances and repeatable geometry.

With dimensions 8 mm (width), 7 mm (height) and 22 mm (length), this key fits common keyways used in industrial machinery. Its compact form and high strength make it suitable for a wide range of power transmission components such as pulleys, gears, couplings, drive shafts, reducers, bearing housings and other mechanical assemblies operating under dynamic loads.

Manufactured from high-quality steel, the key ensures high durability, excellent resistance to torsional forces and long service life. Its standardized dimensions simplify installation and replacement, making it ideal for maintenance operations, production lines and industrial service environments where minimizing machine downtime is crucial.

Key Advantages
