Bellows coupling series NA type stainless steel

Bellows coupling series NA type stainless steel

Bellows, hub part (boss part) use stainless steel. Fixed by special weld. Bellows coupling with high twist rigidity.

[Features]
· The bellows coupling of the NA series is made of all stainless steel.
· Bellows use stainless steel (SUS304L), metal fittings stainless (SUS303) used, and are fixed by special welding
· Precision coupling with higher rigidity compared to NB series, able to withstand high-speed and high-torque.
· Plus, as stainless steel, has excellent corrosion resistance.
· Model no. is 6 for standard, and for non-standard there are 2 model numbers.
· Shaft diameters from 3 mm to maximum 15 mm, constantly stocked with all shaft diameter combinations of millimeter and inch sizes (inside diameter tapping processed).
