The Optibelt SPA 1857 RP is a narrow wedge V-belt from the Red Power 3 S=C Plus series, built for industrial drives that need a compact, high-grip belt. It is commonly found on pumps, fans, compressors and other process equipment where an SPA profile is specified. This page covers how to confirm fit and what to send when requesting a quote.
Narrow wedge V-belts like the SPA 1857 RP transmit power through a 40° angle and a 12.7 mm top width. The 1857 mm length is the datum length used to match the belt to the drive. Before ordering, check the existing belt marking or measure the drive to confirm the SPA profile and 1857 mm length are correct for your application.
When replacing, inspect the pulleys for wear, alignment and correct groove profile. A worn or misaligned pulley can shorten belt life and cause slippage. If the drive uses multiple belts, replace them as a set so the load is shared evenly.
To request a quote, send the part number SPA 1857 RP, the quantity and any drive details you have. If you are unsure about the profile or length, include a photo of the belt marking or the pulley nameplate, and our team can help confirm the right belt for your equipment.

Frequently asked questions
- What does SPA 1857 RP mean?
- SPA is the profile, 1857 is the length in millimeters, and RP identifies the Optibelt Red Power 3 S=C Plus series. The belt has a 12.7 mm top width, 10 mm height and 40° angle.
- How do I confirm this belt fits my drive?
- Check the marking on the old belt or the drive documentation for the SPA profile and 1857 mm length. If you cannot find it, measure the pulley grooves and the drive center distance, or send us a photo of the belt and pulley.
- Can I replace just one belt in a multi-belt drive?
- For drives using multiple belts, it is best to replace all belts at the same time so they share the load evenly. Mixing new and worn belts can lead to uneven tension and premature failure.
