Bando 270L100G Timing Belt L Section 1 in 72 Teeth

Product Description

The BANDO 270L100G is an L-section synchronous timing belt used in light-duty power transmission applications across HVAC, industrial, and mechanical equipment. The belt runs on a 0.375-inch pitch with 72 trapezoidal teeth and measures 27 inches in pitch length with a 1-inch working width. Constructed from neoprene with a fiberglass tension cord, this belt resists heat, oil mist, and the flex fatigue typical in continuous-duty drive systems. It is suited for OEM replacement and maintenance work in fan drives, blower assemblies, and other equipment that uses Series L timing pulleys.

This belt fits Series L timing drive configurations commonly found in residential and light commercial HVAC blower assemblies, refrigeration equipment, and general mechanical systems requiring positive synchronous drive. The trapezoidal tooth profile engages standard L-series timing pulleys and sprockets without slippage, maintaining accurate speed ratios between driver and driven shafts. Licensed HVAC technicians and mechanical maintenance technicians are the primary installers in equipment service and retrofit situations.

Key Features

• Series L section with 0.375-inch pitch and trapezoidal tooth profile for positive synchronous drive
• 72 teeth across a 27-inch pitch length for accurate speed-ratio transmission
• 1-inch belt width for standard L100 pulley and sprocket fitment
• Neoprene construction with fiberglass tension cord for durability under continuous flex
• Rated for operation from -22 degrees F to 194 degrees F
• Lightweight at 0.1151 pounds, minimizing added load on drive shaft bearings

Compatibility

Designed as an OEM-style replacement for Series L synchronous timing drive systems that accept a 1-inch-wide, 72-tooth L-section belt with belt number 270L100.

Installation Notes

Timing belt replacement should be performed by a qualified technician with the driven equipment fully powered down and locked out per applicable LOTO procedures. The drive housing or belt guard must be removed to access the pulleys; verify pulley alignment and check for pulley wear before installing the new belt. Do not force the belt over pulley flanges using sharp tools, as this can damage the fiberglass cord. Reinstall all guards before returning the equipment to service.
