The Sanitaire Style "RD" Belt (2pk), part number 66100, is a high-quality replacement drive belt designed for Sanitaire upright vacuums that require the “RD” belt style. This belt transmits motor torque to the brush roll, enabling the rolling brushes to spin and sweep dirt, hair, and debris from your floors. When your vacuum’s brush roll slows, slips, or stops altogether, this RD replacement restores proper operation and cleaning performance.

These belts are manufactured from reinforced rubber compounds and engineered to precise tolerances. The “RD” style typically features a flat belt with slight ribbing or surface contour to maintain contact and grip. The internal construction includes tensile cords or fibers to resist stretching and degradation over repeated use. Each belt in the 2-pack is built to maintain tension and alignment under load, resisting slippage and sustaining consistent brush roll speed.

Installation is straightforward: open the brush housing, release or remove the old belt, install the new RD belts over the motor and brush roll pulleys, and reassemble the unit. Because two belts are included, you’ll have a spare ready for future maintenance. With proper installation, users will notice restored brush roll rotation, better dirt pickup (especially on carpets), and consistent cleaning performance across various surfaces.
