The DODGE SF-A QD hub is a shaft-mounted power transmission part that carries and secures pulleys, gears, sprockets and similar rotating components. Its split taper design produces a firm, centered grip, so installation and removal can be done without hammering the shaft or the mounted part. It is commonly found on production lines where torque transfer and alignment need to be dependable.

The SF-A code belongs to the DODGE QD series of hubs. The letters in the code identify the size and taper style, and the A suffix marks a construction variant in that series. Order the SF-A hub to match a QD bushing of the same size, so the two parts form a correctly paired assembly. When replacing an existing hub, the code stamped on the old part is the fastest way to confirm what you need.

QD hubs appear in many industries: food processing, cement, steel, paper, textile and agro-industrial plants. They are used on conveyors, mixers, pumps, fans and mills, holding the pulley or gear firmly on the shaft. Because the split taper allows the element to be taken off without damaging the shaft, maintenance crews value them for scheduled service work.

To choose the right hub, check the shaft diameter, the QD bushing size you plan to use and the type of load being transmitted. During assembly, clean the tapered surfaces thoroughly, confirm the bushing and hub are free of burrs, and tighten the screws to the torque listed in the manufacturer's table. Good shaft alignment helps prevent vibration and early wear. The taper itself does not need lubrication, but the part should be kept free of corrosion.

DODGE QD hubs can be swapped with hubs from other brands that follow the same dimensional standard, provided the bushing size and shaft diameter match. That interchangeability simplifies replacement on existing equipment without changing the mounting. If you are unsure about an equivalent, send the original hub code or the shaft dimensions through WhatsApp or email and we will point you to a compatible option. MR supplies DODGE as one of its brands and will quote promptly.

In addition to distributing power transmission components, MR manufactures split plummer block housings, roller chains and sheaves.
