SINOCONVE High Quality SPA SPB SPC Type Transmission Wrapped V-Belt
SPA, SPB and SPC transmission wrapped V-belts are designed for power transmission in industrial machinery and pulley drive systems. The wrapped construction combines rubber layers, polyester cord reinforcement and an outer polyester-cotton canvas to support stable pulley engagement, controlled elongation and durable operation.
The correct belt depends on the section, finished length, pulley groove, center distance, transmitted load, speed, tension method and working environment. Share the existing belt marking and drive details with our team so we can review the application and confirm the suitable specification.

Why buyers choose SPA, SPB and SPC wrapped V-belts
Supports stable pulley engagement
The V-section is intended to seat in a matching pulley groove and transfer power through controlled friction.
Combines rubber, cord and outer fabric
NR/SBR rubber layers, polyester cord and polyester-cotton canvas are listed in the supplied structure information. Confirm the final construction for the intended machine.
Supports replacement identification
The existing section marking, finished length, pulley groove, speed, load and tension method can be checked together before replacement.
SPA, SPB and SPC size reference
| Type | Top width (mm) | Pitch width (mm) | Height (mm) | Length range (mm) | Angle |
| SPA | 13 | 11 | 10 | 475–7200 | 40° |
| SPB | 17 | 14 | 14 | 750–17000 | 40° |
| SPC | 22 | 19 | 18 | 1350–17000 | 40° |
The table reproduces the SPA, SPB and SPC reference supplied in the product material. Confirm the exact section, length and matching pulley before ordering.
Application details we check
- Machine type, drive function and required transmission performance.
- Existing belt section, finished length, top width, pitch width and height.
- Pulley groove profile, pulley diameter, center distance and alignment.
- Transmitted load, motor power, speed, acceleration and start-stop frequency.
- Ambient conditions involving dust, oil, heat, ozone, chemicals or continuous duty.
- Belt tension method, replacement quantity, packaging and required documentation.
Providing these details helps our team reduce back-and-forth and prepare a more accurate SPA/SPB/SPC wrapped V-belt recommendation and quotation.
Customization discussion
Depending on the application, ask our sales team about SPA, SPB or SPC section, finished length, rubber construction, polyester cord, outer fabric, belt matching, packaging and inspection documentation.
