[ ! ] Hardening of this product is induction hardening. (Depth: Approx. 1 mm to 2 mm)

[ ! ] Spline Shafts are hardened, and need to be annealed before machining.

[ ! ] As the accuracy is guaranteed as a set of nut and shaft, they are not sold separately.

[ ! ] A dust-proof seal is attached to the nut, so the balls will not fall off even if the spline shaft is pulled out.
(If the spline shaft is inserted at an angle to the nut, the ball may fall out.)

[ ! ] For BSDMS and BSDSS, only * marked sizes are available, and the Max. L and Y dimensions are in ( ).
[ ! ] For BSDN and BSD2N, only No. 6, 8 and 10 are available.
[ ! ] Operating Temp.: Plastic components are used in ball spline assemblies. Avoid using in high temperature environments: keep below 80°C.

[ ! ] Lubrication: Ball splines are lubricated at the time of shipment, but should be re-lubricated after installation in equipment.
After you start using the vehicle, fill the grease every 100 km.
For re-lubrication, Lithium soap-based grease (Alvania Grease S2 by Showa Shell Sekiyu) is recommended.

Specifications/Overview

 
Precautions for Ball Spline Assembly
■Check Assembly Position
  Match Mark Numbers are entered on nuts and spline shafts (see the diagram on the right).
  When re-assembling, confirm the match mark numbers, character orientations, and positional relationship of parts.
  If the alignment marks are not aligned correctly, the function will be affected.
■Tolerance for Mating Bores
  H7 tolerance is recommended for mating bores for the spline nuts when mounting them on housings.
■For Customers machining the shaft ends
  In order to facilitate nut insertions, chamfer the machined shaft ends,
and remove burrs on the edges of the spline groove with a round file.
