Oldham couplings / grub screw clamping / 1 washer: engineering plastic / body: aluminium / MCZ model / NIHON MINIATURE

Promotional pricing
Volume Discount

Type that fixes the shaft with tightening of a set screw and clamp. Larger shaft hole diameters can be selected.

[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.
