Oldham couplings / hub clamping / 1 disc: engineering plastic / body: aluminium / CCZ / NIHON MINIATURE
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.- Volume Discount

Timing belt profile couplings / grub screw clamping / PU / body: zinc die-cast / MF / NIHON MINIATURE
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.- Volume Discount

Bellow couplings / hub clamping, adapter sleeve / bellows: stainless steel / body: stainless steel / NA BELLOWS-COLLET / NIHON MINIATURE
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.- 2D CAD data available
