BF Series
The 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 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).
There are 3 precision classes C3,C5 and C7.It is suggested to use C3 support units with a C3ball screw.and C5 ball screw can be used with C3 or C5 support units, which enables the support units precision to match the ball screws precision. C7 ball screws should only be used with C7 support units.
Our standard ball screws are supplied with machining that will work with these supports without modification.
