Keyless Shaft Locking Elements.

Combining the SIT-LOCK® design of smooth cone action with superior holding power, the hub can be clamped at any position along a shaft, eliminating the need for lock washers, spacers, stop rings, etc.

Simply by tightening the screws, SIT-LOCK^® keyless locking devices create an axial force on the shaft and the hub that is spread over the entire contact surface. Unlike traditional systems, they offer numerous advantages such as:

Easy assembly and disassembly
Both actions take place by locking and unlocking the clamping screws with common tools. The use of a torque wrench is only necessary when a more precise torque is required.

Superior holding power
The action of the clamping cones creates shaft clamping torque superior to a normal keyed hub.

Overload protection
When the pre-set torque is exceeded SIT-LOCK^® will slip, preventing the connected elements from being broken.

Easy adjustment
Combining the SIT-LOCK^® design of smooth cone action with superior holding power, the hub can be clamped at any position along a shaft, eliminating the need for lock washers, spacers, stop rings, etc.

Precision location
With the SIT-LOCK^® smooth cone action, the SIT-LOCK^® is ideal for clamping cams, timing devices, and indexing mechanisms accurately and precisely.

Temperature
-20°C to 150°C.
Unlimited use possibilities SIT-LOCK^® units are suitable to connect any type of hub (flywheels, chainwheels, gears, levers, pulleys, eccentrics, coupling, etc).

Various solutions in stock
Available in stock in 10 different types, SIT-LOCK^® units can be utilized in a varied range of industrial applications.
