AnswerA 1610 taper lock bush is a standardized mounting component that allows for easy installation and removal of the pulley onto a shaft. It provides a secure, keyed connection. This listing is for the pulley only; the 1610 taper lock bush must be purchased separately according to your specific shaft diameter. Question?What is the difference between pitch diameter (140mm) and outside diameter? AnswerThe pitch diameter (140mm for this SPZ pulley) is the effective diameter at which the V-belt rides in the groove and is used for calculating speed ratios. The outside diameter is slightly larger and is the overall physical dimension of the pulley. For an SPZ profile, the outside diameter would be approximately 144mm. Question?Is this pulley dynamically or statically balanced? AnswerOptibelt pulleys of this size are generally statically balanced according to ISO 1940-1 grade G16. This ensures smooth operation for most standard industrial applications. For very high-speed applications, dynamic balancing might be required. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
