Eliminate shaft slippage and secure your power transmission with our premium-grade Metric Key Steel. Manufactured to exact dimensional tolerances, our key stock provides an ultra-precise, interference-free fit for all your standard metric keyways, pulleys, gears, and sprockets.
❓ How It Works
- A slot called a keyway is cut along the rotating shaft.
- A matching slot is cut inside the hole (bore) of the gear or pulley.
- A piece of key steel is cut to length and placed into the shaft’s keyway.
- The gear or pulley is slid over the shaft, trapping the key between both slots and locking them together.
Key Characteristics
- Tight Tolerances: Key steel is drawn to highly precise dimensions (often conforming to standards like DIN 6880) so it fits tightly into keyways without wobbling.
- Sharp Edges: Unlike general-purpose steel bars, key steel has clean, square corners to ensure full contact inside the slot. [1]
- High Strength: It is typically made from medium-carbon steel (like C45 grade) or stainless steel to withstand massive shearing forces during operation.
Whether you are performing routine plant maintenance, repairing agricultural machinery, or building custom precision drives, our key steel delivers the shear strength and reliability your torque demands.
