Frequently Asked Questions
What belts run on the BK24x1/2?
4L, 5L, A, and B section V-belts. These sections are standardized, so any manufacturer's belts of the correct section and length will run in the grooves.
Does the BK24x1/2 replace the Dodge BK24 X 1/2 sheave?
Yes. Published interchange data crosses the BK24x1/2 directly to the Dodge BK24 X 1/2, as well as Martin BK24 1/2, Gates BK24.1/2, TB Woods BK2412. Verify groove count, diameter, and bore or bushing before ordering.
Why does the BK24x1/2 list two pitch diameters?
Combination sheaves run more than one belt section, and each section rides at a different depth in the groove. The BK24x1/2 has a 1.8 in pitch diameter with A or 4L belts and 2.2 in with B or 5L belts.
Does the BK24x1/2 ship from Houston?
Yes. Stock items ship same day from our Houston, Texas warehouse. Call (888) 203-2358 to confirm availability.
