In engineering word, key is a machine element used to connect a rotating machine element to a shaft. WOODRUFF KEYS are of semicircular shape. The main advantage of WOODRUFF KEYS is elimination of milling near shaft Shoulders. WOODRUFF KEYS are used to improve the concentricity of the shaft for high speed operation. These keys are made up from SAE 1035 carbon steel. They lock pulleys and gears tightly to transmission shafts.

The Woodruff Keys is so called because of its manufacturing method. It consists of a semicircular key seat on the shaft surface which holds the key. The key is in the shape of a section of a circle. This type of key tends to have a lesser shear strength than compared to that of a rectangular or square key.
Woodruff keys are semicircular shaped, such that, when installed, leave a protruding tab. The keyway in the shaft is a semi-circular pocket, the mating part, a longitudinal slot. They are used to improve the concentricity of the shaft and the mating part, which is critical for high speed operation. The main advantage of the Woodruff key is that it eliminates milling a keyway near shaft shoulders, which already have stress concentrations.
Woodruff Keys are generally used for Automobiles, gearboxes, starters, alternators, fuel injection pumps, oil pumps, water pumps and brake compressors, Two wheelers, Electric motors, alternators and switch gears, Machine tools and all types of pumps Textile machineries, Pharmaceutical Machinery, Heavy Duty Machinery, Earth moving Machinery, Automotive Cran etc.
WHAT IS A WOODRUFF KEY?
A woodruff key is a half‑moon shaped machine key that prevents gears, hubs, or other components from moving independently of a rotating shaft or spindle. They also act as a fail‑safe that protects expensive parts by shearing under excessive loads. The crescent profile of the key allows it to sit deeper in the shaft reducing the likelihood of the key rolling laterally out of the groove.
HOW DOES A WOODRUFF KEY WORK?
When installed, the long, flat face of the woodruff key protrudes above the host shaft. When a mating hub, gear, or other component is pressed onto the shaft, the protruding section of the key locks components together.
Installing A Woodruff Key:
When installing a woodruff key, first press it into the semi‑circular groove milled into the shaft. Next, align the top, flat portion of the key so that it is parallel with the host shaft. During installation, woodruff keys will sometimes slip out of their groove as the mating component is pressed on. This can make woodruff keys difficult to install.
How To Keep A Woodruff Key In Place:
To keep a woodruff key in place while installing a mating component, ensure that it is situated tightly in the key seat. Since woodruff keys are made to tight tolerances, they often require a press fit into its seat. This is done by lightly tapping the flat, protruding face of the key with a hammer or mallet until the key is seated firmly. The key will still extend above the mating shaft's surface to lock the mating hub or gear in place. If the key still falls or slips out during component installation, the key is likely too small for the host groove.
SELECTING THE RIGHT WOODRUFF KEY
It is important to understand the different features of a woodruff key during the design phase of an application. Some considerations include key type, key material, and key finish.
What Are The Different Types Of Woodruff Keys?
The two most common woodruff keys are full radius and flat bottom. Both function the same, but may be appropriate for different applications. It is important to note that both radius and flat bottom woodruff keys are standard and either is shipped at the manufacturer's discretion. If a specific type is required, let G.L. Huyett know!
Full radius woodruff keys are a full half circle and make full contact with the groove seat. Full radius woodruff keys require precision of the seat groove as contact can occur between the woodruff key and the bottom of the seat causing interference and the key to protrude from the groove higher than desired.
Flat bottom woodruff keys have the same profile as standard woodruff keys, however, the bottom of the key has been shaved flat. The flat bottom reduces the potential of interference at the bottom of the seat, allowing the woodruff key to seat fully in the groove and alleviating potential clearance issues of excessive key height.
Hi‑Pro keys are a variant of woodruff keys that feature a full radius but have the added feature of feet. When installed, the feet extend over the face of the host shaft, preventing the key from rocking in its rounded seat.
Woodruff Key Materials
Woodruff keys are crafted in carbon, alloy, and stainless steel. Carbon and alloy steel are both durable, however they must be plated or coated to prevent corrosion. Stainless steel surpasses carbon and alloy steel in corrosion resistance, but it is not as strong.
ADVANTAGES OF A WOODRUFF KEY INCLUDE:
- Adjusts to any taper present in mating piece or shaft
- Ideal for high speed rotating assemblies
- Eliminates milling near shaft shoulders reducing stress concentrations at the shaft end
- Deeper seat in the shaft reduces risk of rolling out of key seat
- Provides a more exact fit, reducing play in the key seat
- Easy removal
