Compact Rotary Ball Spline Nut

SPB Rotary Ball Spline

Introducing the SPB rotary ball spline from NB, a compact linear system designed to revolutionize the way design engineers approach linear motion. This series is an embodiment of our commitment to providing innovative, high load, high speed linear solutions that cater to a diverse range of engineering needs across the UK & Ireland, and beyond.

FEATURES ENGINEERED FOR EXCEPTIONAL PERFORMANCE

Compact Footprint: Small but mighty, the SPB series offers heavy load bearing capacity with smaller dimensions, while offering high speed rotational movement.

Ground Spline Shaft: NB ball splines are precision ground to ensure tight tolerances allowing for smooth, quiet, super accurate linear motion.

Large Load Capacity: Despite the compact form the SPB rotary ball spline offers high radial, axial and moment load capacity.

High-Speed Rotation: Due to the design of the rotary portion of the SPB nut utilising angular contact bearings, high rotational motion can be achieved.

High Rigidity: The angular contact bearings, which are aligned in the back-to-back duplex manner means ultra-high rigidity is guaranteed for all applications.

Selectable Preload: The spline section of the SPB assembly is available with selectable preload, allowing you to specify our products to your exact requirements.

Low Noise: Nippon Bearing pride themselves on offering the quietest, smoothest running ball splines in the industry. With the unique recirculation design in both the spline and rotational sections, a low decibel is realised.

High Accuracy: With accuracy figures of just 6µm/100mm, an NB ball spline will suit even the most demanding precision applications.

Two Motions in One: With linear and rotary motion combined into one system, compared to a conventional system, the number of parts is halved, and considerable space saved.

SPECIFICATIONS TO MEET DIVERSE ENGINEERING REQUIREMENTS

Available Sizes: Available in mm diameters 6, 8, 10, 13, 16, 20 and 25 our NB ball splines are designed to suit a wide array of design specifications.

Hollow Shaft: NB ball splines and rotary ball splines are available with hollow shafts to allow for running cables, air piping and weight reduction, ensuring complete flexibility for all applications.
