About FK25 FF25 Ball Screw End Support

There are two main types of supporting a ball screw, floating (often referred to as simple) and fixed. A floating end support has a single radial ball bearing which provides support against radial loads. Fixed-end support takes axial and radial forces on the screw

Precision Engineering for Demanding Applications

Designed to support 25 mm ball screws, the FK25 FF25 Ball Screw End Support features C7 precision rating as standard, with C5 available on request. The structure incorporates single-row, angular contact bearings housed in hardened (HRC 50-55) plastic enclosures. This combination ensures stability and longevity even under high load and high-speed conditions.

Versatile and Reliable Ball Screw Support

With a black anodized or coated finish, this end support set resists corrosion and wear, making it ideal for CNC machines and automation systems. Its grease lubrication and double-sealed bearings contribute to smooth, low-maintenance operation and reliable performance across a wide temperature range (-20C to 80C).

FAQ's of FK25 FF25 Ball Screw End Support:

Q: How do I install the FK25 FF25 Ball Screw End Support for a 25 mm ball screw?

A: To install, align the FK25 (fixed side) and FF25 (floating side) supports with the ends of your 25 mm ball screw. Secure each mount using the flanged base. Ensure the angular contact bearings are properly lubricated and fitted to maintain optimal load distribution and prevent misalignment.

Q: What applications are suitable for the FK25 FF25 Ball Screw End Support?

A: This end support is specifically designed for CNC machines, industrial automation, and equipment requiring precise and stable ball screw operations. Its high-load capacity and robust construction make it suitable for demanding industrial settings.

Q: When should I consider upgrading from C7 to C5 precision rating?

A: Upgrade to the C5 precision rating when your application requires tighter tolerances and improved positional repeatability, such as high-accuracy machining or measuring equipment. For standard industrial use, the C7 grade provides sufficient precision.

Q: Where should I use the FK25 (fixed side) and FF25 (floating side) in my setup?

A: Install the FK25 on the fixed side of your assembly to provide rigid support and maintain axial positioning. Attach the FF25 on the floating side to accommodate thermal expansion and small misalignments, ensuring stable and consistent performance.

Q: What is the benefit of double-sealed angular contact bearings in this product?

A: Double-sealed angular contact bearings provide enhanced dust and particle protection, extending the bearing's lifespan and reducing maintenance needs. They also help retain grease, ensuring smooth operation in challenging environments.

Q: How does the housing material and surface finish contribute to durability?

A: The hard plastic housing (HRC 50-55) combined with black anodized or coated finish offers exceptional wear resistance and minimizes corrosion. This ensures reliable service in industrial applications and harsh conditions.
