Shafts are essential mechanical components used in various industrial applications, particularly in automation and machinery. They are designed to transmit rotational force and motion between machine parts, ensuring efficient power transfer. Common types include drive shafts, coupling shafts, and linear shafts, each serving specific purposes. Key features include high strength, precision machining, and durability to withstand heavy loads and harsh conditions. Materials range from stainless steel to alloy steel, often with coatings for corrosion resistance. Shafts are widely used in motors, conveyors, pumps, and robotic systems, making them a critical category for maintenance, repair, and operations (MRO) in industrial settings.
