FLEXIBLE SPACER COUPLINGS
 |
-
Compact, light, robust, safe in operation, long service life. - Two identical hubs and one flexible element.
- Hubs of high tensile steel.
- Large permissible bores, various hub lengths.
- Driving dogs have smooth surface, high durability.
- Generously proportioned compression-stressed flexible inserts.
- Damps vibrations and shocks, compensates for axial, radial and angular misalignment.
Elastomeric Element features:
- Inserts made of “90 Shore A” Polyurethane (G) as standard or tough “55 Shore D” Hytrel (H).
- Operating temperature range: -40 ° C to +80 ° C as standard
- Elastomeric element is resistant to oil and grease.

Service Factor
The service factor must be chosen according to working conditions between 1 (light duty) and 3 (arduous duty).
Critical Speed & Spacer length
Spacer coupling lengths can be provided up to a maximum of 6m depending on rotational speed. For advice on the critical speed of a given coupling consult Screw Jack.
