For drives that must stay in step, the DODGE HT500 timing pulley delivers motion through a timing belt without slipping, keeping the ratio constant between shafts. It suits equipment where synchronization is essential, such as pumps, compressors, conveyors and machine tools. MR Industrial Accessories supplies this series to customers across the United States and in several Latin American countries, and can help you confirm the right pitch, tooth count and mounting before you order.

Reading the part number makes selection straightforward. In F8MX-36S-21-SH, the F8MX portion gives the pulley type and pitch; 36S is the tooth count and hub style; 21 is the belt width; and SH identifies the taper bushing system. The same pattern appears in F8MX-38S-21-SH, F8MX-40S-21-SH and F8MX-42S-21-SH, where only the tooth count changes. With those four pieces of information, you can match the pulley to the belt and bushing.

These pulleys are common in production lines, mills, food and beverage plants, textile operations and packaging equipment. They also appear on belt conveyors, mixers, blowers, woodworking machines, positive displacement pumps and screw compressors. The timing drive keeps the relative position of the shafts, which matters whenever slipping cannot be allowed.

When specifying, check the belt pitch, number of teeth, belt width and shaft diameter. The SH taper bushing lets you mount and remove the pulley without hammering and simplifies alignment. Make sure the pulley and the mating component are aligned to prevent uneven belt wear. No lubrication is required for this drive type, but belt tension and tooth condition should be monitored. A clean installation with the correct torque on the bushing screws supports service life.

HT500 timing pulleys can interchange with other brands that share the same pitch, tooth count and bushing system, provided the hub dimensions and outside diameter are respected. Pitch alone is not enough; verify belt width and bushing type as well. If you need a special configuration, MR can suggest a compatible alternative or discuss manufacturing options.

If you already have the part number, send it by WhatsApp or email for a prompt quote. If you cannot find it, provide the pitch, number of teeth, belt width and shaft diameter, and we will identify the corresponding option. We can also advise on the bushing and belt so the assembly runs correctly from the first installation.
