Left Hand Threaded Shaft Collars

Ruland Manufacturing introduced its inch and metric left hand threaded shaft collars, available in one- and two-piece clamp styles in steel and stainless steel.

These left hand threaded shaft collars are available in bore sizes ranging from 1/8 inch to 2-1/4 inches and 4 mm to 30 mm.

Each shaft collar has double tapped threads to ensure a precise and burr-free finish allowing for easy installation and removal, proper fit, and extended shaft life. They also feature tightly controlled face to bore perpendicularity (TIR ≤ 0.002 inch or 0.05 mm). The forged screws test beyond industry standards.

The collars are manufactured from 1215 lead-free steel with a proprietary black oxide finish and 303 stainless steel with hardware of like material. RoHS3 and REACH compliant.
