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 10 for applications requiring a balance between transferring torque and 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 BulletPoint5 : 2. G10 grade GCR15 steel ball BulletPoint6 : 3. High speed and low noise BulletPoint7 : 4.

Ball screws are made of carbon steel, which is more wear-resistant and greatly extends the service life of the ball screw. 2. The balls between the screw shaft and the ball screw nut have a lot of rolling motion, and they can achieve higher motion efficiency. 3. Ball screws are widely used in automated machinery, lathes, machine tools, etc. The product description Material : stainless steel Lead means : refers to the axial distance of the corresponding points of the adjacent two teeth on the same helix Pitch means : refers to the axial distance of the corresponding points of the adjacent two teeth on the thread Package Includes: 1x Lead screw 1x Brass nut ProductSiteLaunchDate : 2004-11-09T05:00:01-00:00 Size : 350mm StreetDate : 2017-05-15T00:00:01Z Style : Classic SupplierDeclaredDgHzRegulation : not_applicable UnitCount : 1 UnspscCode : 31000000
