Thin Shaft Collars for Encoders
Ruland thin line shaft collars are designed for the narrow shafts commonly found on hollow bore encoders. Encoder shaft collars from Ruland have reduced width, outer diameter, and weights while maintaining the traditional benefits of Ruland clamp style shaft collars including high holding power, precise face to bore perpendicularity, and hardware that tests beyond DIN 912 12.9 standards. Hollow bore encoders usually require a clamping shaft collar to secure the connection between the male motor shaft and female encoder shaft. Designers benefit from Ruland thin line shaft collars having bore sizes with multiple outer diameter and widths to choose from allowing them to match system needs with shaft collar capabilities. Two-piece styles have a balanced design for high speed applications. Encoder shaft collars are available in aluminum for lightweight and high holding power and 303 stainless steel for corrosion resistance. They are manufactured in our Marlborough, Massachusetts factory in bore sizes ranging from 3/16” to 1-1/2” or 5mm to 40mm.
