Polyurethane timing belts

A polyurethane timing belt transmits power in sync, with no slip, which makes it the right choice when the center distance has to stay exact. You size it by profile and pitch, which must match the timing pulleys; by width, which sets the load capacity; and by length, which follows from the center distance. The polyurethane stands up to abrasion, and the internal tension members hold the pitch under load.

The part number combines profile, length and width. In PHG AT10-1210-16, AT10 is the profile with a 10 mm pitch, 1210 is the length in millimeters and 16 is the width in millimeters. PHG AT10-1480-50 follows the same logic and is 50 mm wide. Length is always a multiple of the pitch, since the belt has a whole number of teeth. Part numbers ending in S, such as PHG AT10-1000-S150, are a different version and must be ordered in full.

Applications include automation, machine tools, packaging, printing, material handling and linear motion, plus any drive where V-belts or poly-V belts can't hold timing. Pair the belt with a pulley of the same profile and set tension to the manufacturer's specification so the teeth don't jump.

We carry SKF in this line. Send the complete part number by WhatsApp or email. If you don't have it, measure the old belt for profile, pitch, length and width, and add another brand's part number if you have one. We'll quote it promptly.
