Frequently Asked Questions

What is a RULAND MANUFACTURING JC12-3-A jaw coupling hub used for?

The RULAND MANUFACTURING JC12-3-A is a zero-backlash curved jaw coupling hub used to connect two rotating shafts in motion-control systems. It is commonly applied in servo motors, encoders, and precision positioning equipment where misalignment compensation and torque transmission are required.

What are the specifications of the RULAND MANUFACTURING JC12-3-A coupling hub?

The JC12-3-A is an inch-series aluminum jaw coupling hub with a 3/4 in outside diameter. It is designed for JC12 coupling size and manufactured by RULAND MANUFACTURING. The part number is JC12-3-A, and it is intended for use with matching curved-jaw spiders to achieve zero-backlash performance.

Where to buy RULAND MANUFACTURING JC12-3-A coupling hubs worldwide?

3G Electric supplies RULAND MANUFACTURING JC12-3-A jaw coupling hubs worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this component to any country.

How to select the correct RULAND MANUFACTURING jaw coupling hub for an application?

To select the correct RULAND MANUFACTURING jaw coupling hub, match the shaft diameters to the hub bore size and confirm the outside diameter (3/4 in for JC12-3-A). Consider torque requirements, misalignment tolerance, and operating temperature. Aluminum hubs suit lighter loads; consult the RULAND catalog for compatibility with curved-jaw spiders.

Used in

Common applications for RULAND MANUFACTURING
Automated packaging machinery — Ruland beam couplings (e.g., PSR20-8-5-A) for connecting servo motors to conveyor drive shafts.
CNC machine tools — Ruland rigid couplings (e.g., CLX-4-4-A) for precise alignment of ball screw assemblies.
Robotic arm joints — Ruland Oldham coupling hubs (e.g., OSC16-6-A) for accommodating axial motion in end-effector drives.
Pump and compressor systems — Ruland stainless steel shaft collars (e.g., CL-3-ST) for securing impeller shafts.
Printing press rollers — Ruland clamp-on beam couplings (e.g., PCR18-8-8-A) for synchronizing roller rotation with minimal backlash.
Material handling conveyors — Ruland set screw couplings (e.g., PSMR29-7-7-A) for linking gearboxes to drive rollers.
