The Optibelt Alpha Torque XL K 512 is a timing belt with an XL profile and a length of 1300.48 mm. This page covers what those two specifications tell you when selecting a replacement or specifying a drive.
The XL profile defines the tooth geometry and pitch. The length of 1300.48 mm is the datum length you need to match or cross to an equivalent. Together, profile and length are the primary selection criteria for a synchronous belt. If your drive or old belt marking shows XL and 1300.48 mm, this part number is the direct starting point.
When you request a quote, include the part number XL K 512 and, if possible, the application details. Our team can confirm the belt or suggest an equivalent based on the profile and length you provide. We carry Optibelt Alpha Torque timing belts and serve maintenance, engineering and purchasing professionals across the United States, Canada, Mexico and South America.
