BK40/BF40 Ball Screw Support

BK40/BF40 Ball Screw Support

Product Description

The BK40/BF40 Support Unit Set is a monumental mounting solution engineered to provide maximum structural stability for large-diameter ball screws, typically used with the 50mm and 63mm series. This industrial-grade matched pair employs the "Fixed-Supported" architecture necessary for high-precision, high-load linear motion.
 

• BK40 (Fixed Side): The Primary Anchor

Serving as the drive-end anchor, the BK40 houses a matched pair of high-precision Angular Contact Ball Bearings. This configuration is specifically designed to absorb massive bi-directional axial thrust loads from high-torque motors, effectively eliminating backlash and ensuring 100% force transmission.

• BF40 (Supported Side): Thermal Expansion Management

The BF40 unit contains a high-quality radial bearing engineered to "float" axially within the housing. This is a critical safety feature for long-travel systems; it allows the screw shaft to expand and contract due to thermal friction without inducing bowing, buckling, or bearing bind.

Key Features & Engineering Advantages

1.Unshakeable Stability: Built for the most demanding machines, our BK40/BF40 units provide the rock-solid foundation needed to move multi-ton loads with microscopic precision.
2.Precision You Can Trust: With matched P5-grade bearings, we eliminate the "slop" and vibration found in standard supports, ensuring your machine delivers a flawless surface finish every time.
3.Built for the Extremes: Constructed from heavy-duty S45C reinforced steel, this housing won't flex or bow under pressure. It is designed to handle the massive "kick" of industrial presses and large-scale CNC gantries.
4.Maximize Machine Uptime: Our superior sealing system keeps metal grit and coolant out of your bearings. Combined with a protective black oxide finish, these supports are engineered to outlast the competition in the harshest environments.
5.Ready for High-Torque Performance: Specifically designed to transmit 100% of your motor's torque into linear motion without lost energy or mechanical deflection.
