NBK Japan MJC-14-ERD Jaw-Type Flexible Coupling for 3-4 mm Shafts - Stainless Steel, 14 mm OD, 22 mm Length, Made in Japan
✔️ 3-4 mm bore (0.118-0.157 in), 14 mm OD (0.551 in), 22 mm length (0.866 in); stainless steel, single unit, zero-backlash tight fit, electrical insulation, made in Japan

NBK Japan MJC-14-ERD is a jaw-type flexible coupling designed to connect small shafts in precision drive assemblies. Its bellows-like jaws tolerate eccentricity, angular misalignment, and end-play, making it handy in robotics, printers, automation, and micro-machinery where smooth, low-backlash torque transfer matters. Pack size: 1.

✅ Tight Fit enables zero-backlash torque transmission at low torque.
✅ Easy Fit allows smooth assembly and partitioning of hub and sleeve.
✅ Bellows design provides tolerance for eccentricity, angular misalignment, and endplay.
✅ Stainless steel body with electrical insulation for safe operation in electronics environments.
✅ Made in Japan; compact, single-unit package ideal for small drive systems.
💡 What is a jaw-type flexible coupling used for in precision miniature drive systems and how does it improve motion accuracy? This section explains the broad use and benefits. - Connects tiny shafts while transmitting torque with minimal backlash. - Accommodates small misalignments and endplay to keep positioning accurate. - Handy in servo/stepper setups, printers, and robotics for reliable, smooth motion. - Durable stainless steel with insulation supports safe, long-term operation. This handy coupling helps keep precise motion, reduces backlash, and improves drive reliability in small equipment.
