GRI rigid couplings have been designed and manufactured to connect two shafts of the same diameter but without allowing any relevant Open the catalog to page 

Rigid couplings connect two shafts with a solid and high-precision-aligned hold. Rigid couplings have been historically economical, and frequently homemade segments for straightforward shaft to shaft associations. To be considered rigid, a coupling would allow less than one degree of deflection or angular movement.

For shaft connections with rigid couplings the shafts must be precisely aligned. In order to avoid any excessive bending load on the coupling bearing must be 

COMPACT ELASTIC COUPLING "GEC" RIGID COUPLING "GRI" Rigid coupling, in steel, suitable for shaft connections with good alignment. Max. torque 450 Nm – max. bore ø 50 mm. Bellow

As the name implies, rigid couplings, which are sometimes called sleeve couplings, are torsionally stiff couplings with virtually zero windup under torque loads, but they are also rigid under loads caused by misalignment. If any misalignment is present in the system the forces will cause the shafts, bearings or coupling to fail prematurely.

Feb 01,  · RIGID COUPLINGS VGS rigid couplings can be used in applications where you require a rigid joint similar to that of a traditional flanged, welded and/or threaded connection. You need not worry about the snaking of the pipe on straight runs, as all VGS rigid couplings utilize both a mechanical and frictional interlock design to provide rigidity.

Rigid and Flexible Coupling: Rigid flange coupling consists of two separate grey cast iron flanges. One keyed to the driving shaft and the other to the driven shaft by means of nuts and bolts arranged on a circle concentric with the axes of the shafts. There are two types of rigid flange couplings; Protected and Unprotected rigid flange coupling.

Couplings - Rigid Topaz's Rigid Couplings feature a tubular threaded type assembly and ensure proper alignment and a secure connection when joining two ends of threaded Rigid conduit. Other applications include bonding threaded conduits to electrical junction boxes or enclosures when used in conjunction with chase nipples and connectors.
