Shaft Collars for Printing Applications
Ruland offers an industry-leading selection of one -and two-piece shaft collars often used in printing applications. Ruland shaft collars have precisely controlled face to bore perpendicularity (TIR ≤ .002" / .05mm) which is critical for proper alignment when collars are used as a load-bearing face or guide for large rolls of paper. Clamp style shaft collars do not mar the shaft, are infinitely adjustable, and have higher holding power than set screw shaft collars. Ruland mates halves of the two-piece collars throughout the manufacturing process to ensure a precise fit and maintain high holding power.
Designers prefer clamp type shaft collars in printing due to the frequent nature with which paper, rollers, and other fixturing need to be changed out or adjusted. Traditional round bore shaft collars are the most used because of their high holding power and relative cost effectiveness. Ruland also offers two forms of quick clamping shaft collar – with cam lever and with clamping lever – giving system designers the option to change out or adjust system components quickly.
Ruland shaft collars fit shafts from 1/8” to 6” and 3mm to 150mm. They are made from select North American bar stock in 303 & 316 stainless steel for corrosion resistance, 1215 lead-free steel for high holding power, high-strength 2024 aluminum for lightweight, and engineered plastic for corrosion resistance and light duty applications. Ruland manufactures shaft collars in our Marlborough, MA factory under strict controls using proprietary processes.
