The Optibelt SPA 857 is a narrow wedge V-belt in the SK metric profile series. It has a 12.7 mm top width, 10 mm height, 40 degree angle and 857 mm length. Before fitting it, inspect the drive and sheaves.
Check sheave grooves for wear, corrosion, burrs or embedded debris. Measure groove width and compare with the SPA profile. Misaligned sheaves or worn grooves can shorten belt life, so correct alignment and clean grooves before installation.
Confirm the old belt marking matches SPA 857. The SPA profile and 857 mm length identify this belt. If the marking is worn, measure the top width, height and outside length to verify the replacement.
Send the part number SPA 857 by WhatsApp or email to request a quote. Include the drive details and a photo of the old belt marking if possible. The team can confirm the belt or suggest an equivalent.
