NIHON MINIATURE
Clamp type, aluminum made Oldham coupling. Prevent slippage by tightening the entire shaft.
[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.

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.

NIHON MINIATURE
Low cost coupling that uses zinc die casting for the hub part (boss part), and urethane rubber for the sleeve.
[Features]
· MF coupling consists of one rubber sleeve and two hubs made of zinc die-cast (surface treated).
· Sleeves and hubs have splines on inner and outer diameters, respectively, which engage and transmit torque.
· Fastening to shaft is by set screw.
