Item description/product images

DescriptionMaterial:Spider polyurethane hardness Shore 98A.
Hub and tube aluminium.
Version:Bright.Note:This coupling series is a simple, cost-effective version with a variable length centre tube and elastomer dog couplings (see 23022) on both ends.
Benefits are the very low moment of inertia, low weight and high permissible displacement values for shaft alignment.
These low maintenance, rust-free couplings have proven to be a good alternative in linear robots for packaging and printing machines.
For the clamping screw tightening torques see technical data for 23022. Please contact us for couplings with speeds in excess of 1500 rpm L4 lengths of more than 2 m.
Max. permissible axial displacement: ±1 mm.
Max. permissible lateral displacement: 5 mm per meter.
Assembly:The combination of the easy fit hub of the dog couplings 23022 and push fit on the intermediate tube guarantees quick and easy assembly or dismantling of the 23025 unit. There is no need of axial displacement of drive unit or drive shaft as the tube with half a dog coupling each end can be fitted between the shaft ends. Only a little force is required to push the coupling hubs into the elastomer spider. The hubs are each tightened onto the shaft or tube ends using only one radial clamping screw after taking account of length L.Advantages:- Plug-in, play-free, vibration absorbing
- For long lengths up to 3 m
- Mounting friendly radial clamping hub
- Up to 400 Nm
On request:Hub bores D1 and D2 with separate tolerance class or range.Drawing reference:
S = displacement for hub
T = insert depth
X = distance between shafts
M = assembly length
Z = intermediate tube
