Key Stock & Woodruff Keys
Loose pulleys and couplers beat up shafts fast. Kimball Midwest's selection of key stock and Woodruff keys helps you lock hubs to shafts and keep torque moving. Go undersize (-0.002") for easier installs in clean keyways, oversize (+0.003") for snug fit and less chatter. Choose zinc plated for rust resistance or stainless for wet, corrosive service. 12" bars, marked or color coded.
