AT5 profile pre-bored timing belt pulleys
Available items: approx. 1–2 working days
Size interpretation: pulley width – pulley profile / pulley number of teeth
Nominal pitch diameter calculation (mm): number of teeth × 5 / 3.14
The pre-bored timing belt pulleys are supplied either with a basic bore or with a centre punch mark, so further machining is required as needed within the specified limits. After machining the bore, the pulleys can also be used as internal tensioners for timing belts when combined with a suitable bearing.
The pulleys are supplied with flanges up to 42 teeth; from 44 teeth upwards they are supplied without flanges.
Material: AT5 pre-bored timing belt pulley body made of aluminium, belt guide flange made of steel.
