Characteristics of Involute Spline

SV and SVI series are made according to the automotive involute spline standard, JIS D 2001 (FLAT ROOT SIDE FIT, Backlash 0.060.15)
Involute spline shafts and bushings are normalized to have good abrasion-resistance.
Allowable torques shown in the table are calculated with the formula given in "Surface durability of spline" in the gear reference section. (=0.75 and =2kgf/mm² assumed)
Spline bushings can also be made from bronze as a special custom order item.
