series of 1 mm pitch polyurethane timing belts are designed for miniature
applications and to run with the new 1 mm pitch timing belt
pulleys. Offered with Kevlar cord reinforcement, the A6B18M Series are
stocked in 22 different groove sizes ranging from 94 to 559 mm (3.701 to
22.008") while the A6G18M Series with fiberglass cord reinforcement are stocked
in pitch lengths from 142 to 705 mm (5.591 to 27.756 inch). These belts come
standard in 3 and 6 mm widths; however, special widths can be cut from sleeves.
Kevlar belts (double span) have a breaking point of 300 N per 1 mm (214 lbf.
per 1/8 in.) and the fiberglass belts, also double span, have a breaking point
of 165 N per 1 mm (117 lbf. per 1/8 in.). Both have a temperature range
of -30 to +85C (-22 to +185F). Since these timing belts are the smallest
standardized pitch timing belts available they are ideal for important
