Bellows coupling series NA type stainless steel (NA-20S-12X15)
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).
