Elastomer dog couplings with radial clamping hub and intermediate tube

Material, surface finish:
Elastomer spider in polyurethane, shore hardness 98-A. Hub in aluminium, natural finish. Intermediate tube: aluminium
Sample order:
nlm 23025-020X0500
(please also indicate dimension L4 = 500 mm)
D1 = 7
D2 = 7
(The hubs are supplied predrilled).
This serie of couplings captivate due to the simple and cost-effective solution with a intermediate tube, which is variable in length and Elastomer Dog Couplings arranged on both sides (see 23022).
Benefits are the very low moment of inertia, low weight as well as the high admissible displacement values for shaft alignment.
In the example of linear robots in packaging and printing machines this low-maintenance, rust-free coupling represents a good alternative.
The thightening torque of the clamping screws see technical data of 23022. By application with more than 1500 r.p.m. speed and a total coupling length L4 of more than 2 m, please contact us first.
Max. shaft displacement axial: 1 mm.
Max. shaft displacement lateral: 5 mm per meter.
- Plug-in, backlash-free, vibration absorption
- customized length up to 3 m
- radial clamping hub for simple installation
- to 400 Nm
On request:
Desired hub holes D1 and D2 seperately with tolerance class or tolerance zone.
