Market positioning as published by SIT Drive Solutions (Belt Drives Offering - Range, May 27, 2023) - for orientation when comparing offers. A listed series is not automatically a direct interchange: confirm section, length designation, power rating and operating limits before replacement.

Applications and Operating Context
General industrial transmission with narrow-section pulley systems.
How to Select the Correct Belt
- Identify the existing pulley groove standard and belt section.
- Record motor power, rotational speeds, pulley diameters, center distance and duty cycle.
- Determine required belt length and the manufacturer length designation.
- Calculate design power with the appropriate service factor and check manufacturer belt power ratings.
- Verify number of belts, belt speed, wrap angle, allowable tension, shaft loads, installation clearance and environmental conditions.
- Validate the final selection against current manufacturer tables.
Replacement / Interchange Engineering
Confirm SP-profile pulley geometry; do not substitute classical and narrow sections solely on nominal width.
A similar-looking belt or a competitor series listed in a market comparison is not automatically a direct interchange. Verify profile geometry, length convention, power capacity, material, temperature, antistatic requirement and drive compatibility.
RFQ Information Required
Belt brand / series and full marking; cross-section; nominal / effective / inside length convention; quantity; number of ribs if banded; pulley groove dimensions; driver power and RPM; driven RPM; operating hours; ambient temperature; contamination; machine application; and photographs of the belt and sheaves.
