Product Description

Oldham Couplings (also known as Cross Slider Couplings) are rigid yet flexible shaft connectors designed to transmit torque between parallel, non-collinear shafts while accommodating parallel misalignment (radial offset). They consist of three components:

• Two Aluminum Hubs (anodized for corrosion resistance) attached to each shaft

  6
  .
• A Central Floating Disc (acetal/nylon) with perpendicular tenons sliding within hub grooves

  3
  .

This design achieves zero backlash, electrical isolation, and acts as a mechanical fuse to protect downstream components during overloads

Feature	Oldham Coupling	Jaw Coupling	Beam Coupling
Backlash	Zero (acetal disc) 2 9	Moderate (elastomer wear)	Zero
Parallel Misalignment	High (up to 0.010″) 2 4	Limited (increases bearing load)	Low (high restorative force)
Failure Mode	Safe decoupling (disc shears) 2 9	Metal-to-metal contact	Torsional deformation
Maintenance	Disc replacement only 4 6	Spider replacement required	Whole-unit replacement
Torsional Stiffness	High (precision motion) 2 9	Moderate	Low (acts like a spring)
