Blower Drive Sprockets

RCD offers a complete line of quality sprockets to fit most requirements and is able to produce special sizes from special materials upon request. All sprockets are CNC machined from solid billet 6061-T6 aluminum bars or solid ZK60A-T5 magnesium round bars. Magnesium bars are ulta-sound tested for imperfections prior to machining. Magnesium has the best strength to weight ratio of any sprocket available. RCD's aluminum sprockets are hard anodize coated for increased wear resistance and our magnesium sprockets are coated to resist corrosion.

RCD offers a complete selection of blower drive sprockets. All blower drive sprockets come with standard 2.00" bore, six 3/8" holes evenly spaced on a 2.782" diameter circle and 0.5" drive flange thickness.

NOTE: The last two digits of a sprocket part number denote the tooth count. (Example: 0000000-54 = 54 tooth.) 14mm, 24 tooth and 8mm, 32-36 tooth top sprockets are available in aluminum 'R 0.75' style only.
