Hyster Woodruff Key BT / Raymond 5-026-005 – HW-1206

This Woodruff key is built for Hyster lift trucks, matching the manufacturer part number used in the equivalent Raymond parts catalog under the same cross-reference set. A Woodruff key is a half-moon shaped piece of steel that fits into a matching semicircular keyway machined into a shaft, locking a gear, pulley, or coupling to the shaft so torque transmits without the two components slipping relative to each other.

Because a Woodruff key carries the full shear load of the rotational force passing between the shaft and the component it locks, it is designed to be a wear point that protects more expensive parts around it. If the key shears under an overload condition, it typically fails before the shaft or gear does, which limits the damage to a low-cost, easily replaced component. A key that has worked loose in its keyway or shows rounding on its edges should be replaced before it slips and lets the coupled parts move independently.

This key is cataloged for Hyster equipment and matches the keyway size called for in the original assembly.
