BK BF Matched Ball Screw Supports

Product Details

The BK unit is installed on the fixed side of the ball screw. Its angular-contact bearing arrangement controls axial movement and supports the thrust generated by the screw.

 

The BF unit supports the opposite end with a radial ball bearing. This end maintains shaft alignment while allowing slight axial displacement caused by assembly tolerances or thermal expansion.

 

Product Description

BK is normally positioned near the motor and coupling, while BF is mounted at the opposite end. Used together, they support the ball screw while allowing it to rotate within the machine structure.

 

The support size must match the ball screw's machined end journals, shoulders and retaining threads. BK and BF numbers of the same nominal size do not mean both ends have identical internal structures. Accurate mounting-surface alignment is required to prevent additional torque, vibration and premature bearing wear.

 

We build to customer drawings under OEM/ODM, and accept orders as small as a single piece for standard sizes.
