Set-Screw Hub
Shaft-hub connection using one or more radially arranged set screws. Cost-effective design for smaller torques, such as miniature couplings. Fitting clearance from 0.01mm to 0.05mm. If possible, avoid damaging the drive shaft with the aluminum ball or flat surface.

Clamping Hub
Installation-friendly shaft-hub connection with a radially arranged clamping screw (DIN-ISO 4762-12.9). KG-HS series with two clamping screws in a 180° arrangement for optimal balancing quality. Safe, backlash-free and non-positive transmission of the nominal torque. Standard tolerance of the hub bore D1/D2 is "G6" or "G7". Permissible fitting clearance from 0.01mm to 0.04mm. Generally with an additional EASY Clamp pin for easy disassembly by widening the clamping hub bore.

Clamping Hub
For the attachment of metal bellows or elastomer couplings to safety couplings, a radial clamping hub is available as a standard shaft-hub connection. This installation-friendly hub type ensures safe, backlash-free and powerful torque transmission.

Split Hub
The split hubs are divided and consist of a fixed and a loose half. The fixed half-shell parts can be placed on the permanently aligned shaft journals. This can make assembly considerably easier, since, for example, there is no need to subsequently move and align the motor shaft. The two clamping screws should be tightened as evenly as possible and the gap dimensions should be checked. Permissible fitting clearance from 0.005mm to 0.04mm. It is essential to check whether the specific coupling dimension "g" is slightly smaller than the frontal shaft distance "A".

This can make assembly considerably easier, since, for example, there is no need to subsequently move and align the motor shaft or one-man assembly is possible. The two clamping screws should be tightened as evenly as possible and the gap dimensions should be checked. Permissible fitting clearance from 0.005mm to 0.04mm. It is essential to check whether the specific coupling dimension "g" is slightly smaller than the frontal shaft distance "A".

Clamping Ring Hub
The SKB series is designed with a clamping ring hub as a shaft-hub connection. The clamping ring is tensioned via a radially oriented clamping screw. The hub bore is slotted twice. This ensures a safe and backlash-free torque transmission. Permissible fitting clearance from 0.01mm to 0.04mm. A keyway is possible upon customer request.

Conical Clamping Bush
A backlash-free, non-positive shaft-hub connection using a conical clamping bush ensures the transmission of very large torques, even with small shaft diameters. The rotationally symmetrical structure ensures high balancing qualities and operating speeds. However, the assembly process is complex and cannot be carried out radially. The cone bushing is pressed in axially by tightening several fastening screws (at least 6 pieces) crosswise, if possible several times crosswise. Permissible fitting clearance from 0.005mm to 0.02mm. Several extraction threads are provided for the loosening process.

Conical Clamping Bush
The SKY series is designed with a conical clamping bush as a shaft-hub connection. This backlash-free clamping connection ensures reliable torque transmission even with small shaft diameters. The assembly process is carried out axially by tightening 6 fastening screws, if possible several times crosswise. Several extraction threads are provided for the loosening process. For the coupling attachment, a conical clamping connection can also be selected.

Conical Clamping Ring Hub
A backlash-free, non-positive shaft-hub connection using a conical clamping ring hub ensures the best possible torque transmission and, thanks to the rotationally symmetrical structure, optimal balancing qualities. In addition, there is no axial displacement of the hub during the clamping process. However, the assembly process is complex due to the tightening of the cone clamping ring using several clamping screws and cannot be carried out radially. Permissible fitting clearance from 0.005mm to 0.02mm. Several extraction threads are provided for the loosening process.

Expanding Cone Hub
Expanding cone hub for compact, integrated attachment to a hollow shaft with a short overall length. Simple, axial operation thanks to a centrally located clamping screw. Variable expansion cone pin ØD2 with standard tolerance "g6" for bore tolerance "H7" - please note D2_min or D2_max!

Flange Hub
One-sided or double-sided flange connection according to "DIN-EN-ISO9409-1" or with customer-specific dimensions. Flange connection in one or two-piece design. Very compact variants with a very short overall length and high torsional rigidity are possible.

Keyway Connection
Optional upon customer request for shafts with an additional keyway in accordance with DIN6885. On request with surcharge. Groove tolerance "JS9" or "P9" as standard. Due to the positive shaft-hub connection, forced driving is guaranteed.

Keyway Connection
The SKW series is designed with a keyway connection by default. This low-backlash hub design is cost-effective, easy to assemble and ensures positive torque transmission without the risk of slipping. Keyway tolerance "JS9" or "P9" in accordance with DIN6885. The hubs of the coupling attachment can also be provided with a keyway upon customer request.

Very seldomly, metal bellows couplings may have resonance sounds (e.g. a whistling or a humming). A type of coupling with significantly higher torsional stiffness or vibration dampening elastomer couplings should be used here.

Electrically insulating couplings, such as elastomer couplings with their plastic element (spider), are required if no static charge may be passed on.
