KCP Taper Grid Coupling Hub, 1140H
Available
The hub is fitted to each shaft in a KCP taper grid coupling, in sizes 1020H to 1150H. A flexible grid sits between the two hubs and moves in lubricated grooves in the hub teeth, which lets the coupling take up parallel and angular misalignment and end float, and gives torsional flexibility under changing load.
A complete coupling uses two hubs, one grid and one cover. The cover comes as a horizontal split aluminium cover (Type H) or a vertical split steel cover (Type V).
Where this product is used
- Drives where shock load or vibration needs to be reduced
- Drives with parallel or angular shaft misalignment, or with end float
- Drives that reverse or need a smooth start
- Replacing pin-bush flange or chain couplings
Features
- Accommodates parallel misalignment, angular misalignment and end float
- Torsionally flexible: the grid flexes to take up changing loads, shock and vibration
- A damaged part can be replaced on its own, rather than the whole coupling
- Covered and lubricated: grease goes in through the lube plug of the assembled coupling
- Suitable where the drive reverses or where a smooth start is needed
- Fourteen sizes, with bores from 12mm up to 203mm maximum

Fitting and use
Grease the grid and the hub teeth before the covers are fitted, then fill the assembled coupling with grease through the lube plug.
Choosing the right option
To size the coupling, work out the design torque. Use the lowest operating speed of the application.
Choose the size whose basic torque is equal to or above the design torque, then check the shaft diameters against the maximum bore of that size. If the bore is too small, step up to the next size. Check the maximum speed for the size and cover type as well.

KCP Taper Grid Coupling Hub, Sizes 1020H to 1150H: 1140H
SKU: A0148882 | Model: 1140H-H
Size 1140H. *** Hub Only *** Grid Coupling Hub Hub taper grid coupling. About KCP Taper Grid Coupling Taper Grid Couplings are recognizable due to their unique steel flexible grid running through the tapered hubs. The benefits of the Grid Coupling are reduced vibration and shock loads. The compact size of shaft-to-shaft couplings. Handle torque capacity due to high strength hardened alloy steel construction Deflect torsionally for normal shock or vibratory loads. Capacity for misalignment without producing the detrimental side loads. Designed with a trapezoidal cross-section and tempered for spring hardness. Increase in strength rating and provide reserve strength for a longer part life. Easy to fit the trapezoidal grids into the slots of the hub and short time of installation. Free to rock, pivot, and float.
