Bellows coupling series NA type stainless steel
NIHON MINIATURE
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).
| Standard Price: | MYR 207.28 |

| Days to Ship: | 6 Day(s) or more |

Bellows coupling series NB type phosphor bronze product
NIHON MINIATURE
Low cost bellows coupling, using phosphor bronze for bellows, and brass for boss part. Nickel plating treatment.
[Features]
· NB series bellows coupling is made with phosphor bronze (PBP3-0), with brass bracket (BsBM) used, both fixed with solder.
· No backlash, low inertia, high torsional rigidity, compact coupling with flexibility.
· Model number is no. 4, with shaft diameter from 2 mm to 10 mm, and always in stock with all shaft diameter combinations (inner diameter tapping processed).
| Standard Price: | MYR 123.58- |

Bellows coupling series Collett type stainless steel
NIHON MINIATURE
Bellows, hub part (boss part) use stainless steel. Spring steel used for shaft fastening bracket. Can be fixed without damage to the shaft.
[Features]
· The performance is the same as the general type, but it is easier to install and remove without damaging the shaft.
· Suitable especially when the frequency of forward and reverse rotation is high, or when the angular rotation acceleration is great.
· Material is the same as general type, bellows are stainless steel (SUS304L), fittings use stainless steel (SUS303), and clamp is spring copper. (Surface treated)
· Shaft diameters are 5 mm to 8 mm, and always in stock.
