SIT-LOCK® self locking elements
Advantages of SIT-LOCK® on the shaft-hub connection compared with traditional systems:
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.
When the pre-set torque is exceeded SIT-LOCK® will slip, preventing the connected elements from being broken. Note: SIT-LOCK® units are not friction couplings so, excessive slip will cause damage.
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.
With the SIT-LOCK® smooth cone action, the SIT-LOCK is ideal for clamping cams, timing devices, and indexing mechanisms accurately and precisely.
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.
