Jason Industrial A18 Rubber V-belt 0.5 X 20 Inches

Product Description

The JASON INDUSTRIAL A18 is a classical A-section rubber V-belt designed for industrial and mechanical drive applications. Measuring 0.5 inches wide with a 20-inch outer circumference, this belt transmits rotational power between sheaves in belt-drive systems. It is manufactured from rubber for flexibility and durability under continuous load. HVAC technicians, millwrights, and mechanical contractors install this type of belt on blower assemblies, fan drives, compressor drives, and general power transmission equipment where a standard A-section profile is specified.

The A18 fits A-section belt drive configurations found in light industrial equipment, commercial HVAC air handlers, rooftop units, and belt-driven blower systems. It is also used in agricultural equipment, shop machinery, and pump drive assemblies where an A-section sheave groove is present. The classical A-section profile is one of the most widely used cross-sections in fractional and integral horsepower drive systems, making this belt a common service and replacement item across multiple trades.

Key Features

• Classical A-section profile for compatibility with standard A-groove sheaves
• Rubber construction provides flexibility and resistance to heat and fatigue
• 0.5-inch width by 20-inch outer circumference dimensions
• Suited for continuous-duty belt drive applications including blower and fan assemblies
• Sold individually as a single belt unit

Compatibility

Designed as an OEM-style replacement for A-section V-belt drive systems requiring an A18 classical profile belt in HVAC, industrial, and mechanical power transmission applications.

Installation Notes

Belt installation and replacement should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all power to the drive system before removing or installing any belt. Never pry or force a belt over a sheave using tools that could damage the belt cord or sheave groove. After installation, verify belt tension and sheave alignment before returning the system to operation.
