The 268-7 drive belts and rings are essential components for the Heathkit HW SB transceivers, a series of popular amateur radio equipment that have been widely used for decades. These drive belts and rings are designed to seamlessly integrate with the transceiver's mechanics, ensuring reliable and efficient operation.
The 268-7 drive belts are made from high-quality materials, specifically engineered to withstand the rigors of continuous use in a radio transceiver. They are made from a durable rubber compound that provides excellent resistance to wear and tear, ensuring long-lasting performance. The belts are also designed to be quiet in operation, reducing unwanted noise that could interfere with radio transmissions.
The drive belts come in a set of two, each with an internal diameter of 1.97 inches (50 mm) and an overall length of 3.94 inches (100 mm). They have a width of 0.28 inches (7 mm) and a thickness of 0.12 inches (3 mm), providing the right balance of flexibility and strength.
The accompanying rings are equally important. They are made from hardened steel, ensuring durability and stability. The rings serve to maintain the tension of the drive belts, ensuring they run smoothly and consistently. Each ring has an outer diameter of 2.25 inches (57 mm) and an inner diameter of 1.97 inches (50 mm), perfectly fitting the drive belts and the transceiver's mechanics.
In summary, the 268-7 drive belts and rings are essential components for the Heathkit HW SB transceivers. They are made from high-quality materials, ensuring long-lasting performance and reliable operation. The belts are quiet and durable, while the rings provide the necessary tension to keep the belts running smoothly.

At one time during production this location had a spring and dial cord assembly instead of stretched belt. Just a bit of history. The o-rings drive belts I have been selling for over ten years are sized to adequately turn with pulleys W/O exerting too much stress on rotating components. See one picture showing locations.
These are made of high quality nitrite rubber which has been used in replacements for many years now. That started causing bearing problems in the loading capacitor because belt was stretched too much which resulted force on bearings. Six o-rings total, one set for now and as a spare.
Us shipping only. For sale are two sets of three new o-rings use in the Heathkit 5-band transceivers hw-1 hw-101, sb-1 sb-101 and sb belts or same size used on driver final tuning controls one belt is larger load control. Therefore the load control o-ring is larger than other two. Heathkit originally used the same size belts part no.
