Material and application note
The legacy material describes high loads, low elongation, fatigue endurance, oil/heat/ozone/abrasion resistance, static conductivity to ISO 1813 and a temperature range of -55°C to 70°C. Confirm the applicable construction, test documentation and operating range before treating these statements as product guarantees.
A-type wrapped V-belt construction
Reinforced wrapped construction
The supplied structure lists NR/SBR rubber layers, polyester cord reinforcement and an outer polyester-cotton canvas. Confirm the final construction for the intended machine.
Industrial transmission selection
The designation, belt marking, pulley groove, finished length, speed and load should be reviewed together before replacement.
Layered rubber and cord structure
The legacy material identifies top rubber NR/SBR, polyester cord, buffer rubber NR/SBR, bottom rubber NR/SBR and polyester-cotton outside fabric.
Applications
The supplied legacy material lists blending systems, choppers, HVAC systems, lawnmowers, compressors, crushers and scarifiers. Suitability depends on the machine, pulley system, load, speed and working environment.
Why buyers choose an A-type wrapped V-belt
Supports stable pulley transmission
The V-section is intended to seat in a matching pulley groove and transfer power through controlled friction.
Supports multiple replacement designations
A64 through A89 designations shown on the product page can be checked with the complete belt marking and finished dimensions before replacement.
Supports specification-led purchasing
Providing the belt marking, pulley data, load and speed helps reduce replacement errors and quotation back-and-forth.
Classical section reference
| Type | Top width (mm) | Pitch width (mm) | Height (mm) | Reference length (mm) | Angle |
| A | 13 | 11 | 8 | 330–8000 | 40° |
| B | 17 | 14 | 11 | 457–17000 | 40° |
| C | 22 | 19 | 14 | 700–17000 | 40° |
| D | 32 | 27 | 19 | 1100–17000 | 40° |
| E | 38 | 32 | 23 | 3300–17000 | 40° |
This table reproduces the classical section reference from the legacy material. The A64–A89 product designations should not be treated as direct length conversions without confirming the complete belt marking.
