jbj Techniques Limited Shaft Locking Devices

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. » 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 preset 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. » 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, chain-wheels, 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. A shaft to hub lock is critical in the design of a mechanical transmission as an unsuitable choice could cause serious damage to the machine or system and result in economic loss. SIT-LOCK® Shaft Locking Device / Coupling 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. Contact us or see our website for further information.
