T20 Pilot Bore Timing Pulleys for Polyurethane Belts
TTrapezoidal/Trapezprofil
The T profile is a trapezoidal standard profile in a metric pitch for conventional timing belt applications. The tooth geometry allows a play-free belt/sprocket pairing that results in unsurpassed precision.20 timing pulleys are the basic type of pulleys for polyurethane belts with a trapezoidal TTrapezoidal/Trapezprofil
The T profile is a trapezoidal standard profile in a metric pitch for conventional timing belt applications. The tooth geometry allows a play-free belt/sprocket pairing that results in unsurpassed precision.20 profile. They are made from aluminium alloy as unbored or with a pre-drilled hole. Designed according to DIN 7721.
The pulleys are supplied as a semi-finished product and the bore must be modified before mounting the pulleys on the shafts.

Notice
The catalog data sheets serve only as a recommendation for the types and dimensions of aluminum alloy pulleys for standard widths and numbers of teeth. All T20 pulleys are custom made only.
Timing pulleys in the T versions can also be made to order in the "SE" reduced backlash version and the "0 backlash" / "0-Lücke" version with zero backlash.
