ปลอกคอเพลา (SHAFT COLLARS)
Ruland manufactures shaft collars in multiple styles to fit shafts ranging from 1/8" to 6" and 3mm to 150mm. They are made from select North American bar stock in 303 & 316 stainless steel, black oxide and zinc plated carbon steel, high-strength aluminum, and engineered plastic. Each shaft collar is stamped with the Ruland name and bore size for ease of identification. Ruland shaft collars have precisely controlled face to bore perpendicularity (identified by the grooved face) TIR ≤ .002" (.05mm) with tighter tolerances on bearing locknuts. Perpendicularity is critical for alignment when a shaft collar is used as a load-bearing face, mechanical stop, or for mounting components. All Ruland shaft collars are carefully made in our Marlborough, MA USA factory under strict controls using proprietary processes and RoHS3 and REACH compliant.
