Jaw Couplings
Couplings connect two shafts for the purposes of power transmission between the driver and the driven device.
The type of coupling used depends on factors including speed power and shaft alignment.
NBC offers an an extensive range of coupling systems to meet the specific requirements of customers, we can provide specific solutions across a diverse range of industries.
Our range includes
- Rigid
- Tyre
- HRC
- Grid
Key Features
- Wide stock range for most industrial purposes
- Can absorb shock loading & drive misalignment resulting in extended machine life
- Maintenance-free with long life expectancy
- Effective operation
Our engineers design, manufacture, and supply components to your exact specification. Contact us to discuss your project.
Jaw couplings consist of 2 machined hubs with a variety of elements between them to cater for the demand of low cost, general purpose couplings. They absorb some shock loads and limited misalignment. They are ideally suited to machinery driven by standard IEC electric motors. Available with taper sleeve fitting, or bored and keyed for even easier assembly, for shafts up to 100mm or 4”.
What are the Typical Uses for Couplings?
- Conveyor drives
- Compressors
- Roller table drives
- Mixers
- Pumps
- Generator Sets
- Line Shafts
