[ ! ] 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 BASKFS and BASKSS, only * marked sizes are available, and the Max. L dimension is in ( ).
[ ! ] For BHSN and BHS2N, 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.
