SINOCONVE 3L Type Pentagonal V-Belts for Compact Machinery with High Flex Resistance

3L Pentagonal V-Belt

3L is a pentagonal V-belt with a 0.38 inch top width, 0.22 inch thickness, and 40° belt angle. The product knowledge workbook confirms the section dimensions but does not provide a verified inside-length production range for this type. Inside length Li must therefore be confirmed from the required belt marking, sample, drawing, or pulley layout before production. The reinforced tensile structure and durable rubber body provide stable transmission, resistance to abrasion, heat, oil, and repeated flexing, and dependable service in textile equipment, packaging machines, printing machinery, electronic equipment, and compact industrial drives. Custom marking and OEM packaging are available.

Technical Data

Model Naming Rule

Model = section + confirmed inside length Li in inches. The Li value must be verified before the model is created.

Available Models

3L custom inside-length models are available after specification confirmation.

Typical Applications

Textile equipment, packaging machines, printing machinery, electronic equipment, and compact industrial drives.

Selection Notes

Please provide the complete belt marking, required Li length, pulley dimensions, operating load, speed, quantity, and application conditions. No unverified length range has been added. Final specifications and warranty terms are subject to the order contract.
