Machine / Parallel Keys as per IS 2048:1983 standard are precision-machined components used to transmit torque between shafts and hubs. Manufactured from high-grade steel for accurate fit, strength, and durability, ensuring secure mechanical coupling in rotating assemblies.
Machine / Parallel Keys conforming to IS 2048:1983 are essential mechanical components designed to lock rotating machine elements, such as pulleys, gears, and couplings, onto shafts. They provide a positive drive connection, ensuring effective torque transmission without slippage.
These keys feature parallel sides and square or rectangular cross-sections, precision-ground for accurate alignment and tight fit within keyways of the shaft and hub. Manufactured from high-tensile carbon steel, alloy steel, or stainless steel, they are hardened and ground to maintain high wear resistance and dimensional stability under heavy load conditions.
Available in both square and rectangular types, as per IS 2292 (Tolerances) and IS 2048 (Dimensions) standards, parallel keys are ideal for industrial machinery, motors, gearboxes, pumps, and transmission systems.
