Couplings
A coupling links two shafts and absorbs the misalignment that is always there. No installation is perfectly aligned; the coupling has to transmit torque and swallow what is left over, rather than passing it to the bearings as load. A misaligned coupling can finish the bearings behind it within weeks.
Types and variants
The distinct designs that sit under this category.
Flexible (elastomer element) couplings
Damp vibration and torque shock — the most common motor-to-pump link.
Gear couplings
High torque with limited angular misalignment — the heavy industry choice.
Grid couplings
A sprung grid element transmits torque while softening shock.
Locking assemblies
Replace a keyed joint with a friction-based, backlash-free connection.
Where it is used
The applications this category most often serves.
- Motor-to-pump and motor-to-gearbox connections
- Fan and compressor sets
- Agitators and mixers
- Conveyor drive shafts
What we ask when selecting
What we need in order to find the right part. You do not need all of it — we can work out the rest together.
- Torque and speed
- Peak and starting torque count alongside the nominal figure.
- Type of misalignment
- Parallel, angular and axial misalignment call for different coupling types.
- Shaft sizes and keyways
- The two shafts may differ in diameter — the hubs are bored accordingly.
- Temperature and chemical exposure
- The elastomer element is the part the environment affects most.
Other categories in this group
Send us the designation or the dimensions — we will find the match.
A code you cannot find in the catalogue, a faded marking on an old bearing, or just the dimensions — any of the three is enough. The wrong bearing costs more than a late one.
