Drive Belts - Industrial and Bearing Supplies

A 6A 6 | BoschBosch Raw-Edge Cogged Belt ( V-Belt )Replaces all belt types: wrapped belts,raw-edge plain belts as well as coggedbelts.Longer service life - up to three timesthat of wrapped belts.Made to original equipmentspecifications.Runs more quietly.Internal cogged construction minimises bending energyloss and ensures maximum torque transmission.Bosch quality made to Original Equipment Specifications.High tensile cord construction gives longer service life.BELT SIZE DESIGNATIONTop FabricTensile CordsCompressionRubberLaminatedBottom FabricMoulded Cog.Strong, wear resistant, bias-cut fabricprotects the top of the belts withoutlosing flexibility.Pre-stretched, strong polyester cords areplaced in a straight line, providing lessstretch and high horse power rating.Fibre chip reinforced rubber compound isused to provide high friction coefficiency,excellent wear resistance & high flexibility.Crack resistant, highly flexible fabricimpregnated with oil and heat resistantrubber compound.Unique cog design resulting in longer flexlife over small high speed sheaves.Example :Belt typeAutomotiveBelt Length11 A 090013 A 1395eg: 0900 = 900mm1395 = 1395mmBelt Typea (mm))α [º]b(mm)Belt Type 11A 13A 15A 17A 20AWidth - a[mm]Height -b[mm]10.7 13.3 17.3 18.8 22.88.0 9.0 11.0 11.0 13.0α [º] 38 38 38 38 38Bosch Automotive Aftermarket 2008 | 2009
