Clearaudio Thin Silent Belt

A Seamless Silicone Belt, One Millimeter Thick and 304 Across

The Clearaudio Silent Belt is sold each, one belt per turntable. This is the thin version, 1 millimeter. It is molded in silicone with no seam and no join anywhere around its circumference, and it measures 304 millimeters — 12 inches — in diameter.

A seam is a thick spot, and a thick spot passing over the pulley once per revolution is a cyclical speed error. Molding the belt as a continuous loop removes that failure mode entirely rather than minimising it.

Seamless Silicone, and Why the Thickness Matters

Fit and Materials

The belt is silicone, 1 millimeter thick, 304 millimeters in diameter, with no seam or join. It is made for the Clearaudio turntables that specify a 1 millimeter Silent Belt. Clearaudio builds the belt in two thicknesses across the range and they are not interchangeable — thickness is part of the fitment, not a preference.

Check which one your turntable takes before ordering. The simplest way is to measure the belt you are replacing: this one is 1 millimeter, and the Standard Silent Belt is 2 millimeters at the same 304 millimeter diameter.

Who Is the Thin Silent Belt Best For?

• Your Clearaudio takes the 1 millimeter belt — measure the old one if you are not certain
• Your belt is glazed, slack or broken — the part that stops a turntable dead
• You want no seam in the drive — a molded loop has no thick spot to pass the pulley
• You would rather have a spare — a belt fails without notice and the deck is unusable until one arrives
• Your turntable takes the 2 millimeter belt — that is the Standard Silent Belt, and the two are not interchangeable

How Do You Fit It?

Lift the platter off — on most decks it lifts straight up, sometimes with a sub-platter under it. Slip the old belt off the motor pulley and the sub-platter, and wipe both with a clean, dry cloth. Loop the new belt around the sub-platter, then over the pulley, keeping it flat and untwisted. Refit the platter and spin it by hand before switching on.

Pairs Well With

What most owners replacing a belt shop next.

• Stylus force gauges — the other setting that drifts quietly over the years
• Record cleaning solutions — a new belt deserves clean records under the stylus
• Record brushes — a dry sweep before every side
• Cartridge alignment tools — worth re-checking whenever the platter comes off

Frequently Asked Questions

How many do I need?

One. The belt is sold each and these are single-belt turntables.

How do I know if I need 1 mm or 2 mm?

Measure the belt you are taking off, or check your turntable's manual. Both Silent Belts are 304 millimeters in diameter; only the thickness differs, and it is a fitment figure rather than a choice.

When should I replace a belt?

When it looks glazed or feels slack, when the platter takes longer than it used to to reach speed, or when speed will not settle. A belt hardens and stretches gradually, so the change creeps up on you.
