FAQ

Question? What does “AT5 / 18 DF” signify in the part number?

Answer: “AT5” refers to the tooth profile (AT-series) and the pitch (5 mm between teeth). “18” indicates it’s designed for a timing belt up to 18 mm wide (a common standard would be 16mm). “DF” stands for Double Flange, meaning it has a guide flange on both sides to prevent the belt from walking off the pulley.

Question? This pulley has a pilot bore. What does that mean for installation?

Answer: A pilot bore is a small, un-keyed, preliminary hole. It must be machined (bored and possibly keywayed) to the exact diameter and specification of the drive shaft it will be mounted on. This allows for a precise, custom fit in your specific application.

Question? What material is this pulley made of and what are its advantages?

Answer: This pulley appears to be made of zinc-plated steel. Steel offers excellent durability, wear resistance, and high torque transmission capabilities, making it suitable for demanding industrial applications. The zinc plating provides corrosion resistance.
