Some machines don’t fail because torque is too high they fail because maintenance is too hard. Spacer couplings solve that quiet, day-to-day problem by keeping a deliberate gap between connected shafts, so components like pump seals, impellers, bearings, or gearbox elements can be accessed without disturbing the driver setup. At JobWurx, our spacer couplings are built for real plant conditions: tight spaces, repeated shutdowns, and alignment realities that don’t match textbook drawings.
A spacer coupling isn’t simply “a coupling with extra length.” The spacer section is engineered to maintain DBSE (Distance Between Shaft Ends) while transmitting torque smoothly and consistently. In many pump and motor assemblies, that removable middle section becomes the reason downtime stays controlled because you can pull the spacer and service the unit without shifting the motor or redoing the base alignment from scratch.
JobWurx manufactures spacer couplings with a clear focus on fit, balance, and practical installation: clean bolt access, predictable tightening, and repeatable assembly for maintenance teams.
Spacer couplings from JobWurx are commonly specified in:
Wherever shafts must be connected but not crowded together, spacer couplings keep the system workable.
Spacer-type designs are often chosen when access is required and minor operational shifts are expected. The spacer (drop-out) section is typically sized to match the DBSE requirement, while the hub and element selection defines how much angular or parallel misalignment can be accommodated. Correct selection depends on torque, RPM, allowable misalignment, and whether the application sees shock loads (mixers, crushers) or steady loads (pumps, fans). A properly sized spacer coupling reduces unnecessary movement at the bearings and helps protect seals by avoiding forced alignment corrections during maintenance.
JobWurx spacer couplings can be produced in multiple configurations depending on duty and environment:
| Coupling Size | Spacer Length (mm) | Bore Range (mm) | Rated Torque (Nm) | Max Speed (RPM) | Angular Misalignment (°) | Material |
|---|---|---|---|---|---|---|
| SC-100 | 100 | 20 – 40 | 150 | 6,000 | 1.0 | Carbon Steel / Alloy Steel |
| SC-140 | 140 | 25 – 50 | 300 | 5,000 | 1.0 | Carbon Steel / Alloy Steel |
| SC-180 | 180 | 30 – 65 | 600 | 4,000 | 1.0 | Carbon Steel / Alloy Steel |
| SC-220 | 220 | 40 – 80 | 1,000 | 3,000 | 1.0 | Carbon Steel / Alloy Steel |
| SC-260 | 260 | 50 – 100 | 1,500 | 2,500 | 1.0 | Carbon Steel / Alloy Steel |
