DCV Series Drive Features
	Two Face Movable Design for standard V-belts. Maintains belt alignment between the variable speed pulley and the companion sheave. This is an important feature with close center distance drives. Models 257 and 265 are an exception, however, and should use recommended shaft center distances.
	Pulley Face Material Models 140, 150 AND 157 use a light weight, corrosion resistant, aluminum alloy material. Models 167, 257 and 265 use close grained cast iron faces.
	Permanently Lubricated Moveable Face Bushings High load carrying precisely fit bronze bushings with a specially formulated oil impregnation are used to eliminate most fretting and corrosion problems. For severe corrosion conditions the pulley shaft can be treated to resist the particular corrosion condition.
	Torque Sensing Design Belt tension is regulated to the load requirements. Bushing wear is reduced by the peripheral support of the cam followers. There are no torque carrying keys.
