The Optibelt Super X-Power 5VX 840 is a cogged narrow V-belt for industrial drives where a standard 5V belt would run hot or slip. The raw-edge cogged construction is common on higher-speed, smaller-pulley equipment such as compressors, fans and pumps. Confirm fit by matching the 5VX profile and the 2134 mm length to your existing belt.
This belt is a good candidate when a drive needs a narrow wedge profile but the pulleys are small enough that a wrapped belt would flex too hard. Cogged narrow V-belts are widely used on air handlers, vacuum pumps, grain augers and similar machinery where the belt bends sharply around a small sheave.
To confirm the fit, read the marking on the back of the old belt. You are looking for the profile 5VX and a length of 2134 mm. If the old belt is worn or the marking is gone, measure the outside length and check the sheave groove width against a 5VX profile. The same size is also listed under Dayco 5VX 840.
Send the part number 5VX 840 and the quantity you need by WhatsApp or email. If you are unsure whether this is the right belt for your drive, include a photo of the old belt marking and the sheave dimensions. The team can help confirm the belt or suggest an equivalent.

Frequently asked questions
- What does the 5VX profile mean for my drive?
- 5VX is a narrow V-belt profile. It fits sheaves designed for 5V cross sections. If your pulley grooves are wider or narrower, this belt will not seat correctly.
- How do I confirm the length?
- Check the marking on the back of the old belt for 2134 mm. If it is unreadable, measure the outside length of the old belt and compare it to 2134 mm.
- Can I replace a 5V belt with this 5VX belt?
- Only if the drive is designed for a cogged narrow V-belt and the sheave profile matches 5VX. A standard 5V belt and a 5VX belt are not always interchangeable. Send your old belt details for confirmation.
