Stock Drive Products/Sterling Instrument (SDP/SI), a Designatronics brand and US-based manufacturer of precision gears and high-quality mechanical components, offers a unique fastener known as Shaftloc®. This locking device provides a reliable method for securely mounting mechanical components onto a shaft.
Designed as a reusable and cost-effective alternative to traditional fastening methods, Shaftloc® offers product designers and device manufacturers enhanced flexibility and performance. The simple, two piece Shaftloc® design allows for quick and easy mounting or repositioning of hubless gears, sprockets, and pulleys, without compromising torque or performance. Installed using standard tools, the inner and outer sleeves, which have hexagonal heads, feature a unique thread profile that delivers strong clamping force, resists vibration, and provides fully adjustable, quick lock and release functionality.
Shaftloc® is available in four styles – A-Type, M-Type, Double Ended, and Single Ended. The Double-Ended style secures components between two opposing hexagonal heads. In contrast, the Single-Ended styles feature both hexagonal heads on the same side, keeping the face of the mounted component unobstructed. Features include all stainless steel construction, applicable for small shaft diameters and will not damage the shaft.
"The SDP/SI Shaftloc® design offers design engineers and OEMs a smart, efficient solution for securing components to a shaft," says Simon Brazier, director of sales at Designatronics. "Its compact two piece construction simplifies assembly and adjustment, enabling precise positioning without the need for keyways or set screws."
