Description

Poly Chain® GT™2 Sprockets Poly Chain GT sprockets use the tooth profile designed and developed by Gates and function with Gates Poly Chain GT belts in all existing constructions. These sprockets are statically balanced to make sure the entire belt drive is as safe as possible. Furthermore, they are manufactured, specified, and tested to perfectly support the full power capabilities of the Gates Poly Chain belt product range. Belts and sprockets used together get the best out of your belt drive: maximum performance, prolonged antistatic properties and optimal lifetime. WARNING: Do NOT use these sprockets with rim speeds in excess of 6,500 fpm. Smaller, narrower sprockets save shaft space, keep the load closer to bearing and extend life of reducer. Poly Chain® GT® Sprockets keep overhung load below manufacturers' recommendation. Precisely manufactured and statically balanced to ISO 1940 (1973) to class G16. Details shown which do not affect drive function or overall weight may be changed without notification. On a sprocket, pitch is the distance between groove centers and is measured on the pitch circle of the sprocket. The pitch circle of the sprocket coincides with the pitch line of the belt mating with it. The pitch diameter of the sprocket is always greater than its outside diameter. Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more grooves do not have flanges.

Details shown which do not affect drive function or overall weight may be changed without notification. On a sprocket, pitch is the distance between groove centers and is measured on the pitch circle of the sprocket. The pitch circle of the sprocket coincides with the pitch line of the belt mating with it. The pitch diameter of the sprocket is always greater than its outside diameter. Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more groves do not have flanges.

Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more groves do not have flanges.
WARNINGDo NOT use these sprockets with rim speeds in excess of 6,500 fpm.

Abbreviations used for sprocket materials: GI=Gray Iron, DI=Ductile Iron, SiS=Sintered Steel, ST=Steel, CI=Cast Iron. Details shown which do not affect drive function or overall weight may be changed without notification. On a sprocket, pitch is the distance between groove centers and is measured on the pitch circle of the sprocket. The pitch circle of the sprocket coincides with the pitch line of the belt mating with it. The pitch diameter of the sprocket is always greater than its outside diameter. Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more groves do not have flanges.
WARNINGDo NOT use these sprockets with rim speeds in excess of 6,500 fpm.

Abbreviations used for sprocket materials: GI=Gray Iron, DI=Ductile Iron, SiS=Sintered Steel, ST=Steel, CI=Cast Iron. Details shown which do not affect drive function or overall weight may be changed without notification. On a sprocket, pitch is the distance between groove centers and is measured on the pitch circle of the sprocket. The pitch circle of the sprocket coincides with the pitch line of the belt mating with it. The pitch diameter of the sprocket is always greater than its outside diameter. Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more groves do not have flanges.
WARNINGDo NOT use these sprockets with rim speeds in excess of 6,500 fpm.

Details shown which do not affect drive function or overall weight may be changed without notification. On a sprocket, pitch is the distance between groove centers and is measured on the pitch circle of the sprocket. The pitch circle of the sprocket coincides with the pitch line of the belt mating with it. The pitch diameter of the sprocket is always greater than its outside diameter. Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more groves do not have flanges.

Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more groves do not have flanges.
WARNINGDo NOT use these sprockets with rim speeds in excess of 6,500 fpm.

Abbreviations used for sprocket materials: GI=Gray Iron, DI=Ductile Iron, SiS=Sintered Steel, ST=Steel, CI=Cast Iron. Details shown which do not affect drive function or overall weight may be changed without notification. On a sprocket, pitch is the distance between groove centers and is measured on the pitch circle of the sprocket. The pitch circle of the sprocket coincides with the pitch line of the belt mating with it. The pitch diameter of the sprocket is always greater than its outside diameter. Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more groves do not have flanges.

On a sprocket, pitch is the distance between groove centers and is measured on the pitch circle of the sprocket. The pitch circle of the sprocket coincides with the pitch line of the belt mating with it. The pitch diameter of the sprocket is always greater than its outside diameter. Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more groves do not have flanges.

Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more groves do not have flanges.
WARNINGDo NOT use these sprockets with rim speeds in excess of 6,500 fpm.

Details shown which do not affect drive function or overall weight may be changed without notification. On a sprocket, pitch is the distance between groove centers and is measured on the pitch circle of the sprocket. The pitch circle of the sprocket coincides with the pitch line of the belt mating with it. The pitch diameter of the sprocket is always greater than its outside diameter. Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more groves do not have flanges.
WARNINGDo NOT use these sprockets with rim speeds in excess of 6,500 fpm.

Notes
Abbreviations used for sprocket materials: GI=Gray Iron, DI=Ductile Iron, SiS=Sintered Steel, ST=Steel, CI=Cast Iron. Details shown which do not affect drive function or overall weight may be changed without notification. On a sprocket, pitch is the distance between groove centers and is measured on the pitch circle of the sprocket. The pitch circle of the sprocket coincides with the pitch line of the belt mating with it. The pitch diameter of the sprocket is always greater than its outside diameter.
