Automation 4 Less

 

Automation 4 Less stocks a wide range of sizes of ball screw end supports in the two "families" shown above.

  • The BK/BF end supports are sometimes referred to as "pillow block" style. Mounting holes are provided to bolt these to the base where your ball screw will operate.
    • The BK "fixed" end support contains two angular contact bearings that provide both axial and rotational support for the ball screw.
    • The BF "simple/floating" support has only a standard ball bearing that provides rotational support on the end of the ball screw opposite of where the drive occurs (typically a motor or pulley).
    • Our standard ball screws are supplied with machining that will work with these supports without modification.

  • The WBK/WBF end supports are sometimes referred to as "flange" style. Mounting holes are provided in flanges, and bores in brackets on your machine receive the round bearing body. Bolts fasten the flanges to secure in place.
    • The WBK "fixed" end support contains two angular contact bearings that provide both axial and rotational support for the ball screw.
    • The WBF "simple/floating" support has only a standard ball bearing that provides rotational support on the end of the ball screw opposite of where the drive occurs (typically a motor or pulley).
    • Our standard ball screws are supplied with machining that will work with these supports without modification.
    • Note that WBK supports are the same as FK supports, and WBF supports are the same as FF supports. Different manufacturers use different naming conventions for the parts, but these are identical in terms of size and function. Our present supplier identifies by WBK/WBF.
