Ruland Manufacturing Oldham Coupling Disc OD16/25-NL

SKU CH-CSQY-SNZ2V

Oldham coupling disc handles 10 in-lb maximum torque and 4,500 RPM with 0.5-degree angular and 0.008-inch parallel misalignment capacity

  • Handles 0.5° angular misalignment for smooth operation
  • Accepts 0.008 in parallel offset to reduce shaft stress
  • Nylon Grade 11 disc resists wear at 4,500 RPM
  • 10 in-lb rated torque with 140 in-lb break strength
  • 9 in-lb/Deg stiffness ensures precise motion control

Coupling Disc OD16/25-NL

This Oldham coupling disc transmits torque between shafts while accommodating misalignment. It suits motion-control applications where precise angular and parallel offset compensation is required. The nylon disc operates within a one-inch outside-diameter envelope.

Replaces Worn Discs In Existing Hubs

The disc fits hubs with a one-inch diameter and matches the OD16/25-NL specification. Swapping a degraded disc restores the original 10 in-lb torque rating and 7.9 in-lb/Deg torsional stiffness. Replacement is worthwhile when backlash or vibration exceeds acceptable limits for the drivetrain.

Handles 4,500 RPM With Limited Axial Travel

The nylon disc rated Grade 11 delivers a maximum torque of 10 in-lb and a break torque of 140 in-lb. It accepts 0.5 degrees of angular misalignment and 0.008 in of parallel offset. Axial motion is restricted to 0.004 in, so applications requiring greater end-play need a different coupling style.

Highlights

  • Handles 0.5° angular misalignment for smooth operation
  • Accepts 0.008 in parallel offset to reduce shaft stress
  • Nylon Grade 11 disc resists wear at 4,500 RPM
  • 10 in-lb rated torque with 140 in-lb break strength
  • 9 in-lb/Deg stiffness ensures precise motion control

Questions about this item

What outside diameter does the OD16/25-NL disc need to match on the hub?

The disc is made for a 1 in hub diameter, so the hub must measure 1 in to fit correctly.

How do you install the nylon disc between the two hubs, and what step is often missed?

Slide the disc into the slots of both hubs, then tighten the set screws evenly; the step often missed is checking that the disc seats fully before final torque.

When will the nylon disc need replacement based on its torque rating?

The disc is rated for 10 in-lb maximum torque and 140 in-lb break torque; replace it if the application approaches or exceeds the 10 in-lb limit.
