Adjustable Pitch V-Belt Pulleys
2AK double groove pulleys are manufactured for two banded A-series v-belts or two single A-series v-belts, as well as multiple 3L v-belts can also be used with these pulleys. 2AK double groove sheave pulleys are commonly known as double AK pulleys and range in diameter from 2.00" to 18.25," but custom ones are also available upon request. Double AK series pulleys are typically used in medium to heavy-duty agricultural and industrial applications. Our double v-belt pulleys are manufactured using state-of-the-art techniques combined with premium high-performance and high-strength features like grade 35 cast iron instead of grade 25.

Installation and Removal of Pulleys
1. Check the pulley groove to make sure there are no scratches or sharp edges and all dimensions are up to standard;
2. Clean the surfaces of all parts, such as hub holes, taper sleeves, bolt holes, etc. Fit the cone sleeve into the pulley, aligning all the screw holes.
3. Apply oil to the screw (TB 1008-TB 3030) and thread (TB 3525-TB 5050) and screw them into the mounting holes, but do not tighten them yet.
4. Clean the surface of the drive shaft, push the pulley with the tapered sleeve installed to the predetermined position on the shaft, and check whether the V-belt pulley is aligned.
5. When using the keyway, it must be inserted into the hub first, and there must be a certain tolerance between the keyway and the hole hub.
6. Using a hexagonal wrench conforming to the DIN911 standard, alternately, gradually, and evenly tighten the bolts in each mounting hole until the torque shown in the table below is reached.
7. After a short period of operation (0.5 to 1 hour), check the tightening torque of the bolts and retighten them if necessary.
8. To prevent the intrusion of foreign matter, fill the hole's connection hole with grease.
1. Loosen all the bolts, take out one or two of the bolts according to the number of disassembly holes, lubricate the bolt pattern and the tip of the bolt with oil, and insert the bolt into the disassembly hole.
2. Tighten the bolts alternately until the taper sleeve and pulley are loosened.
3. Remove the taper sleeve and pulley from the shaft.
