RULAND MANUFACTURING Jaw Coupling Hub: JS16 Coupling Size, 1 in Outside Dia, Inch, Aluminum

The RULAND MANUFACTURING JS16-4-A is a zero-backlash curved jaw coupling hub used to connect two shafts in motion-control systems, such as servo motors and encoders. It accommodates misalignment while transmitting torque smoothly. Common in packaging, robotics, and CNC machinery, this aluminum hub provides lightweight, corrosion-resistant performance in precision industrial applications.

The RULAND MANUFACTURING JS16-4-A is a curved jaw coupling hub with JS16 coupling size and a 1 in outside diameter. It is made of aluminum for lightweight, low-inertia operation. The manufacturer part number is JS16-4-A. This inch-series hub is designed for zero-backlash torque transmission and fits standard curved jaw spider inserts.

To select the correct RULAND MANUFACTURING jaw coupling hub, match the bore size to your shaft diameter and confirm the coupling size (e.g., JS16) fits the required torque and misalignment. The outside diameter (1 in for JS16-4-A) must clear surrounding components. Always verify the hub material—aluminum for low inertia, steel for higher torque—and use the manufacturer's catalog for ratings.
