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 |

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.
| Standard Price: | MYR 258.93- |

Super zero Oldham couplings series SCZ type stainless steel.
NIHON MINIATURE
Stainless steel hub (boss part), with zero backlash. Stronger and more compact coupling.
[Features]
· Super zero Oldham coupling achieves zero backlash, with improved machining accuracy
· Stronger and more compact design, that can now be used with high precision equipment impossible until now.
· Stainless steel series added, becoming 4 series, with further improvements.
· Materials used are, engineering plastic for spacer, and stainless steel SUS303 for hubs, aluminum series uses aluminum alloy (alumite surface treatment).
· Easy to handle coupling, with low moment of inertia, large swing rigidity, good electrical insulation, and maintenance-free, easy assembly.
· Two types of super zero Oldham coupling, with set screw or collet shaft fixing methods both available, that can be freely combined.
· Stainless steel has no. 4 model number, and the aluminum series has no. 10 model number.
· Stocking stainless steel series from ø4 to ø28, aluminum series from ø3 to ø40 in millimeter and inch system of inner diameter finish.
