Specification Brand : Boston Gear BulletPoint1 : Transmits torque between parallel shafts to provide rotational power to another part of a motorized system BulletPoint2 : Pressure angle of 14.5 degrees for a higher contact ratio between gears, resulting in quieter operation than larger pressure angles BulletPoint3 : Diametral pitch of 4 for applications where transferring torque is more important than controlling changes in speed and direction of rotation with precision BulletPoint4 : Low carbon steel (.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion Color : One Color ExternallyAssignedProductIdentifier : 9345664742660 ExternallyAssignedProductIdentifier1 : 781711098745 ExternallyAssignedProductIdentifier2 : 0781711098745 ItemName : Boston Gear NL22B Spur Gear, 14.5 Pressure Angle, Steel, Inch, 4 Pitch, 1.125" Bore, 6.000" OD, 2.000" Face Width, 22 Teeth ItemPackageDimensions_Height : 13.716 centimeters ItemPackageDimensions_Length : 18.288 centimeters ItemPackageDimensions_Width : 18.796 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : spur-gears Manufacturer : Boston Gear Material : Alloy Steel ModelNumber : NL22B NumberOfItems : 1 NumberOfTeeth : 22 PartNumber : NL22B ProductDescription : 1.
