Ruland has expanded its offering of threaded shaft collars by adding inch and metric left-hand threaded styles to give designers more flexibility to work with standard off the shelf components. Units are available in one- and two-piece clamp styles in steel and stainless steel with bore sizes ranging from 1/8 to 2-1/4 in. and 4 to 30 mm.
The company double taps threads to ensure a precise and burr-free finish allowing for easy installation and removal, proper fit, and extended shaft life.
Equipment manufacturers benefit from the tightly controlled face to bore perpendicularity of the shaft collars (TIR ≤0.002 in. or 0.05 mm) which is said to be critical when they are used as a load bearing face or for aligning components such as bearings or gears.
Forged screws test beyond industry standards to ensure maximum holding power.
Left hand threaded collars are manufactured from 1215 lead-free steel with a proprietary black oxide finish and 303 stainless steel with hardware of like material.
