Description
OPTIBELT 50 AT5K6 / 2900 AFX belongs to timing belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 50 AT5K6 / 2900 AFX and any equivalents.
This Optibelt Alpha Flex timing belt carries the part number 50 AT5K6 / 2900 AFX. The marking on the back of the belt identifies an AT5 profile with a 5 mm pitch and a 2900 mm length. Use those three values to confirm the belt before you order.
The profile sets the tooth shape and the pitch sets the distance from one tooth to the next, so an AT5 belt at 5 mm pitch only fits a pulley cut for that profile. The 2900 mm length is the figure to match against the old belt or the drive drawing. If your current belt is marked 50 AT5K6 / 2900 AFX, this is the same part.
We carry the Optibelt Alpha Flex line for timing belt drives. To request a quote, send the part number 50 AT5K6 / 2900 AFX by WhatsApp or email. If you are unsure, send the full marking from the back of the old belt and the team will confirm the profile, pitch and length.
For drives that run more than one belt, replace the set together so the load stays even across the pulleys. Inspect the pulleys for wear or debris at the same time, since a worn pulley will damage a new belt.
