Smooth, strong and gentle on your cables.
Andreoni pulleys let you redirect your cable, change the angle of pull, or double the resistance of a single-cable machine. They're made from durable aviation-grade aluminum alloy, and the wheel runs on bearings for a very smooth, quiet glide.

Choose your size

	Large	Small
Wheel diameter	2.4" (61 mm)	1.32" (33.5 mm)
Height × width	4.8" × 3.2" (122 × 81 mm)	2.9" × 1.82" (74 × 46 mm)
Breaking strength at the attachment	32 kN (7,194 lbf)	20 kN (4,496 lbf)
Breaking strength per cable side	16 kN (3,597 lbf)	10 kN (2,248 lbf)
Max rope or cable diameter	16 mm (0.63")	12 mm (0.47")
Wheel	Bearing-mounted, ultra-smooth	Bearing-mounted, ultra-smooth

All kN ratings are breaking strengths, not working loads, so always use the pulley well below them. Both sizes are still far stronger than any home cable machine needs. The real difference is how gentle they are on your cable.

Which size is right for you?

Small pulley: lighter, precise work. Ideal for exercises with less weight, like lateral raises, curls, tricep extensions, face pulls and other exercises for smaller muscles. It's compact and light, so it's quick to set up and easy to move.

Large pulley: heavy loads and high tension. Built for heavier lifting and high cable tension, such as multiplying the resistance on a VOLTRA or another single-cable machine. Its bigger wheel is also gentler on your cable under heavy load.

Why a bigger wheel protects your cable

Every time a cable runs over a pulley, it bends, and the tighter the bend, the faster the cable wears. Two standard engineering formulas show why:

Bending stress: σ = E × d ÷ D
E = stiffness of the cable material · d = diameter of the cable's individual strands · D = wheel diameter

Pressure on the cable: P = 2T ÷ (D × d)
T = cable tension · d = cable diameter · D = wheel diameter

In both formulas, the wheel diameter D is on the bottom: the bigger the wheel, the less stress and pressure on your cable. With the same cable, our 2.4" Large wheel puts about 45% less bending stress and pressure on it than our 1.32" Small wheel.

Doubling the resistance on VOLTRA or another single-cable machine?

A popular trick on single-cable trainers like VOLTRA is to run the cable around a pulley to double the resistance. In that setup, the machine's cable wraps around the pulley wheel under full tension on every rep, which is exactly what the formulas above describe. VOLTRA uses a synthetic cable, and a small wheel bends it sharply rep after rep, so it wears out faster. Each replacement cable costs money and puts your machine out of action, so with a small pulley the cost adds up over months of heavy training. For doubling resistance, choose the Large pulley.

DESCRIPTION

✅Double the Resistance of a Single-Cable Machine

Anchor the end of your machine's cable, run the cable around the pulley and clip your handle to the pulley. The resistance at the handle doubles, while the handle travels half the distance. It's the go-to trick on single-cable trainers like VOLTRA when you need more load. For this setup, choose the Large pulley: its bigger wheel is much gentler on your cable.

✅Change the Angle of Pull

Anchor the pulley low, high or to the side to redirect your cable and create new pulling angles that your machine can't reach on its own.

✅Build Your Own Cable Setups

Pair your pulley with Andreoni extension cables. The 20" and 40" cables work with pulleys to create even more exercises, from two-handle setups to barbell work on a single cable machine.

✅Protect Your Cable

Every bend over a small wheel wears your cable a little more. A bigger wheel means less bending stress and less pressure on your cable, so it lasts longer. That matters most with synthetic cables and heavy loads.

✅Which Size Should I Choose?

Large: for heavier weights and high cable tension, like multiplying the resistance on a VOLTRA, and for synthetic cables.

Small: for exercises with less weight, like lateral raises, curls and other exercises for smaller muscles, and for compact, lightweight setups.

Care & inspection

Inspect before each use. Retire the pulley if a side plate is cracked or bent, the axle is loose, or the wheel no longer spins smoothly.
Wipe clean with a dry cloth and keep grit out of the wheel.

⚠️ Safety warning: For gym and fitness equipment only. Not certified for climbing, rescue, fall protection or any use that supports a person's body weight, regardless of any markings on the pulley. The kN ratings are breaking strengths, not working loads, so always use the pulley well below them.
