One SBS 4.0 square belt only—not a complete belt kit.
For Sansui SC-3330. The model reference specifies SBO 4.0. Our belt vendor recommends same-circumference SBS belts as substitutes for SBO belts; the actual belt supplied is SBS 4.0, not an original-profile SBO belt.
- Inside circumference: approximately 4.0 inches (10.2 cm)
- Supplied profile: small square SBS, approximately 0.046 inch square
- Referenced profile: thinner square SBO, approximately 0.039 inch square
- Quantity supplied: 1 belt
Substitution disclosure: SBS and SBO are not identical cross-sections. This application relies on our vendor's same-size substitution recommendation. Confirm the exact model/revision, belt path, pulley fit and free movement before operation. Do not replace a different circumference with this size.
The reference establishes the original belt size but not its operating position. This listing does not identify an unverified belt as the capstan or main drive belt.
Disconnect power before service and follow the equipment service documentation. Photo represents the belt family, not the equipment or a kit.
