A single supplier page catalogues seven ball spline shaft variants spanning light, medium, and heavy duty series with matching nut and bearing options. [S1]
Specifying engineers evaluating ball spline shafts for combined rotary and linear motion get a direct view of available series, accuracy grades, preload levels, and nut geometries from one manufacturer line, which simplifies cross referencing against existing THK, NSK, or Hiwin installations. The page lists shaft sizes from 10 mm through 80 mm, three nut types (straight, flange, rotary), and optional anti-corrosion coatings and grease retaining seals, all of which feed directly into a bill of materials and a preload versus stiffness trade study. Engineers working on robotics, pick and place, or semiconductor machinery can map torque, speed, and contamination requirements to a specific series without leaving the page. [S1]
What the source actually describes
The page is a manufacturer product overview for a ball spline product line, presenting the component as a high precision linear motion element that combines rotary and linear movement in a single compact structure. [S1]
It positions the ball spline against robotics, semiconductor machinery, pick and place systems, and precision assembly equipment, and groups seven distinct shaft and nut variants under one product family. [S1]
The variants, sizes, and design details stated
The product family includes LBS, LBF, LBH, SLS, LF, and LBST series, with size codes spanning LF10 and LF20 and LF30 at the light end, LBH15, LBH20, and LBH35 in the heavy slider range, SLS25 and SLS30 in solid and hollow high torque form, and LBST15, LBST20, and LBST80 as the heavy load series. LBS30UU is also listed separately. [S1]
The SLS series is described as a high torque ball spline with a ball retainer for high speed response, low noise, and long life, and the source states rolling friction transmission efficiency greater than 90 percent. The LF series is described as a medium torque type with 2 to 3 protrusions on the outer ring of the spline shaft and 2 rows of balls totaling 4 to 6 rows of load bearing steel balls for easy preload application. [S1]
The general description names high strength alloy steel as the base material, with advanced heat treatment and surface hardening, and lists options including anti-corrosion coatings, grease retaining seals, and maintenance free configurations. Multiple nut types are listed as straight, flange, and rotary. [S1]
What it means for ball spline specification
For an engineer writing a specification, the page is useful as a menu of configurations rather than as a load rating document. It confirms that the supplier offers three nut geometries and a size range covering roughly 10 mm to 80 mm shaft diameters, which is the range needed for most pick and place and small robot axis designs. [S1]
The stated efficiency figure for the SLS series at greater than 90 percent is a useful baseline for power budget calculations, but it is a self declared marketing number and should be confirmed against independent test data before being written into a machine specification. The LF series description of 2 to 3 outer ring protrusions and 4 to 6 rows of load bearing balls is a structural detail that affects preload stiffness and should be cross checked against the catalogue drawing. [S1]
Optional features such as support bearings, end machining, and seal configurations support a plug and play build, which reduces integration time on space constrained axes but requires the engineer to confirm backlash, repeatability, and life ratings on the supplier drawing rather than on the web page text. [S1]
How to verify at the source
Go to the product page at the source URL and request the downloadable catalogue for each series of interest, since the body text references a download section but does not publish load life curves, accuracy grades, or dynamic load capacities on the page itself. [S1]
Cross check any LBS, LBF, LBH, SLS, LF, or LBST model code against the published catalogue drawing to confirm shaft diameter, nut type, preload class, and the actual number of effective load carrying ball rows, because the body text only states the structural count for the LF series and leaves the other series descriptions at a marketing level.
