BOLTTE Aluminum Rigid Shaft Couplings - 20-65 mm Outer Diameter
BOLTTE Aluminum Rigid Shaft Couplings - 20-65 mm Outer Diameter
These one-piece, slotted 6061 aluminum rigid shaft couplings provide a clamp-type connection for motor, lead-screw and machine-shaft assemblies. They have an oxidized surface and do not compensate for shaft misalignment or vibration, so confirm the assembly and both bore dimensions before ordering.
Size range
- Outer diameters: 20 mm, 25 mm, 32 mm, 40 mm, 45 mm, 50 mm, 55 mm and 65 mm.
- Overall lengths: 20 mm to 80 mm, according to the selected configuration.
- Available bore ranges are listed in the configuration selector.
- This is a rigid coupling and does not compensate for shaft misalignment or vibration.
Specify Both Shaft Bores
- Select the outside diameter and overall length from the listed configuration; available bore ranges depend on that selection.
- Enter both shaft bore dimensions, D1 and D2, in the order requirements. They may differ within the selected bore range.
- Confirm shaft tolerances, any keyway requirements and installation clearance before ordering.
- For the Custom Size / Machining Deposit option, enter all required dimensions before purchase. This option is a machining deposit, not a fully specified standard-size coupling.
Frequently Asked Questions
Can the two shaft bores have different diameters?
Yes. D1 and D2 may differ within the selected bore range. Enter both exact dimensions in the order requirements and confirm the associated tolerances.
Will this coupling compensate for shaft misalignment?
No. This rigid coupling does not compensate for shaft misalignment or vibration.
Does selecting the outside diameter also specify the shaft bores?
No. Select the outside diameter and length, then provide D1 and D2 within that configuration's bore range. Confirm keyway requirements and installation clearance as well.
What is the Custom Size / Machining Deposit option?
It is a machining-deposit configuration for a custom size. Provide all required dimensions in the order requirements before purchase; do not treat the option name as a complete dimensional specification.
