This Optibelt ZR timing belt has an L profile and a 990.6 mm length. The profile identifies the tooth form, and the length sets the belt's pitch circumference. Use these two values to confirm the belt matches your drive before requesting a quote.
The L profile is a synchronous belt tooth form. The 990.6 mm length is the value to compare with your existing belt or drive specification. Both numbers appear in the part number L 390, so the marking on the belt back gives you a direct match.
When you request a quote, send the part number L 390 and the quantity you need. If you are replacing a belt on a drive, check the pulley teeth and the belt width against the current setup. The Optibelt ZR series is a timing belt line we carry, and the L profile with 990.6 mm length is the identifying combination.
For maintenance and purchasing teams, the profile and length are the two fields that prevent a wrong fit. Confirm them against the old belt or the drive documentation, then send the part number by WhatsApp or email. We reply promptly and can help confirm the right belt.
