Frequently Asked Questions

What belts run on the 2BK45H?

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 2BK45H replace the Dodge 2BK45QT sheave?

Yes. Published interchange data crosses the 2BK45H directly to the Dodge 2BK45QT, as well as Martin 2BK45-H, Gates 2BK45QT, TB Woods 2BK45. Verify groove count, diameter, and bore or bushing before ordering.

What bushing does the 2BK45H use?

A H series QD style bushing, sold separately. H is an industry-standard bushing size, so any manufacturer's standard H bushing fits. Order the bushing bore that matches your shaft diameter.

Why does the 2BK45H list two pitch diameters?

Combination sheaves run more than one belt section, and each section rides at a different depth in the groove. The 2BK45H has a 3.5 in pitch diameter with A or 4L belts and 3.9 in with B or 5L belts.
