Drive Couplings
Category Selection
It is very common to see rotating shafts on industrial machinery. Oftentimes these are misaligned as it is nearly impossible to make a perfect alignment when coupling two shafts together. Drive couplings can be used to couple the shafts of various mechanical devices and to compensate for shaft misalignment, reducing stress on shafts and bearings.
SIM and SureMotion drive couplings are available in a range of styles and sizes to meet shaft coupling needs.

Jaw Coupling Hubs and Spiders
Jaw-style drive couplings are popular and cost-effective components for low-inertia applications. Choose spiders of specific durometers for different degrees of shock and vibration reduction.
- SureMotion and SIM brands
- Clamp style hub
- High axial misalignment range
- Fail-safe operation
- Electrical isolation
- Spiders available in three different degrees of durometer, stiffness and torque ratings
- Best for low inertia applications
- Used for both general and high-speed applications
Oldham Coupling Hubs and Torque Discs
Oldham drive couplings are designed for applications where high axial misalignment exists, acting as a mechanical fuse to prevent damage to other components in over-torque conditions. Select a torque disc to match the coupling size.
- SureMotion and SIM brands
- Clamp style hub
- High parallel misalignment range
- Electrical isolation
- Hub material: High strength aluminum
- Disc material: POM (polyacetal) or Delrin™
- Zero backlash
Servo Beam Couplings
Servo beam drive couplings are designed for high-speed servo applications, offering the flexibility of bellows couplings plus torsional stiffness, zero backlash and the strength of disc couplings.
- SureMotion and SIM brands
- Clamp style hub
- Cost effective
- Construction material: 7075-T6 aluminum alloy or 416 stainless steel
- Great for high-speed and high-torque applications
- Zero backlash
Servo High Gain Couplings
Servo high-gain drive couplings are designed for high-speed servo and stepper applications, offering zero backlash, increased control gain, high durability and a wide torque range.
- SIM brand
- Increased control gain (high-gain)
- Excellent vibration absorption
- Electrical isolation
- Ideal for high precision applications
Double Loop Couplings
Outstanding resistance to acids, alkalis, solvents, oils, grease, ozone.
- SureMotion brand
- High torsional rigidity
- One-piece design
- Hubs made of series 300 stainless steel
- Double loop made of DuPont Hytrel™
- Corrosion protection
- Electrical isolation
- Damping of shock and vibration
- Not recommended for applications where inertia is a factor
