The Optibelt 25 T5K6 / 4200 AFX is a timing belt from the Alpha Flex series. The T5 profile and 4200 mm length are the two dimensions to confirm against your drive before you request a quote.
The T5 profile is a metric synchronous profile with a 5 mm pitch. The 4200 mm length is the datum length for this belt. Together, the profile and length define how the belt seats in the pulleys and how it runs on the drive, so both values need to match the belt you are replacing.
For a quote, send the part number 25 T5K6 / 4200 AFX along with the profile and length from your old belt. If the marking on the back of the belt is worn, send a photo of the drive and the pulley teeth so we can help confirm the right belt or suggest an equivalent.
We carry Optibelt belts and serve maintenance, engineering and purchasing teams in the United States, Canada, Mexico and South America. Send your request by WhatsApp or email and the team will reply promptly.
