Browning 4TC86 4-Groove V-Belt Pulley

Browning 4TC86 is a TC Gripbelt four-groove bushed sheave for drives using A- or B-section V-belt systems, part of Browning’s TC-series line. Cast-iron construction provides rigidity and wear resistance, and the four-groove geometry accommodates Browning belts in both A- and B-section configurations, with a through-bore range of 3/4 in to 2-7/8 in compatible with standard bushings. The outside diameter is 8.95 inches, the overall width is 3.5313 inches and the face width is 3.25 inches, while pitch diameters are 8.4 inches for A-belts and 8.9 inches for B-belts. A 1/2-inch (0.5 in) keyway enables secure shaft mounting, and the bore is designed to accommodate Browning bushing options typical of TC-series bushed sheaves. This four-groove Browning pulley combines precise dimensional tolerances with a robust metal body to support reliable belt engagement in industrial belt-drive applications.
