Lead-free carbon steel shaft collars with RoHS-compliant yellow zinc plating are now available. The zinc plating offers high quality anticorrosive properties, yet these shaft collars are less costly than stainless steel alternatives. Parts are plated using a RoHS-compliant trivalent process instead of the non-compliant hexavalent process. Collars come in a variety of materials including 303 stainless steel, 316 stainless steel for increased corrosion resistance, aluminum, black oxide carbon steel, and engineered plastic. Bore sizes from 1/8 to 6 in. are available, and collars come in one and two-piece clamp-style designs. Ruland Manufacturing Co. www.ruland.com (508) 485-1000
