Bando 187L050G Timing Belt L Section 50 Teeth

Product Description

The BANDO 187L050G is a Series L timing belt designed for synchronous power transmission in light-duty industrial, HVAC, and equipment drive applications. It features a trapezoidal tooth profile with 50 teeth, a 0.375-inch pitch, and an 18.75-inch pitch length. The belt body is molded from neoprene with a fiberglass tensile cord, giving it good resistance to heat, oil, and flex fatigue under continuous operation. At 0.5 inches wide and 0.138 inches in belt height, this belt fits standard L-series pulleys and sheaves. Licensed HVAC and mechanical technicians, as well as equipment service professionals, install this belt as a direct drive component in blower assemblies, fan drives, and light machinery.

The 187L050G suits residential and light commercial equipment that uses L-section synchronous belt drives. Common install scenarios include air handler blower drives, small compressor drives, and OEM equipment where the L-series belt standard is specified. The belt is rated for operating temperatures from -22 degrees F to 194 degrees F, making it appropriate for both indoor mechanical rooms and unconditioned equipment spaces. When the input belt number 187L050 is called out on a drive schematic or nameplate, this BANDO belt is the corresponding replacement.

Installation Notes

Installation is typically performed by a licensed HVAC technician or industrial equipment service professional. Disconnect and lock out all power to the unit before removing the drive cover or tensioning hardware. Do not pry the belt onto a pulley with a screwdriver or sharp tool, as this can damage the tensile cord. Verify pulley alignment and correct center distance before tensioning the replacement belt.
