The 316 stainless-steel collars 475feature screws in the same material to prevent corrosion. A high level of resistance to chloride corrosion makes these collars suitable fomarine applications.
The yellow-zinc-plated shaft collars are plated using a RoHS-compliant trivalent process. The zinc plating makes the products less expensive than stainless-steel counterparts. These collars have less holding power than black-oxide-finished carbon-steel versions because of the zinc’s reduced coefficient of friction.
The high-strength-grade aluminum shaft collars with an anodized finish are lightweight, have low inertia, and withstand the recommended screw torque to provide the holding power similar to carbon steel. These collars come with steel screws for higher torque and holding power.
