Model Numbers and Specifications Detailed tables provide model numbers, dimensions, transmissible torque, thrust, and contact pressure for both AD-N and AE Series. The tables also include notes on stocked models and calculation guidelines for combined torque and thrust values.

Hub Configuration

Coefficient K3: Used for calculating hub diameters, with values of 0.6, 0.8, and 1.0 depending on installation conditions.
Installation Examples: Provided for hubs with and without guide portions, detailing minimum hub diameters required.

Notes: Safety rates are not included in the figures; users must consider them before operation. The document emphasizes the importance of calculating hub diameters using specified formulas and coefficients.

Installation Procedures

Guidelines are provided for installing hubs with and without guide portions, with specific hub configuration coefficients (K3) for each scenario.
Examples illustrate the minimum hub diameter required to tolerate internal pressure (P').

Tables and Data

Tables provide detailed measurements for hub diameters, contact pressures, and yield points of hub materials.
Data includes MPa and kgf/mm² values for various models and installation conditions.

Notes and Recommendations

Safety rates are not included in the figures; users should consider them before operation.
Hub diameters should be calculated using specified formulas, with different coefficients for various installation examples.

SL Series Specifications and Procedures
The SL Series includes models designed for shaft and hub connections, featuring specifications such as transmissible torque and thrust, shaft and hub contact pressures, and locking bolt details. The wedging action between the inner ring and taper rings applies radial pressure to the hub, enhancing the connection strength. Proper installation requires consideration of the clearance between the product and the hub shoulder to ensure standard torque is achieved.

ML Series Features and Specifications
The ML Series offers self-centering units suitable for narrow and wide hubs, providing easy installation and removal. The construction includes inner and outer rings, a nut, and a retaining ring. Specifications detail transmissible torque, thrust, and contact pressures, with guidelines for hub diameters based on material yield points.

EF Series Features and Specifications
The EF Series shares inner and outer diameters with the EL Series and is designed for accurate shaft-hub alignment. It consists of inner and outer rings and locking bolts. Specifications include transmissible torque, thrust, and contact pressures, with hub diameter calculations based on installation conditions and material properties.

Installation and Safety Considerations
For all series, proper installation is crucial to achieving the desired performance. Safety rates are not included in the provided figures, and users must consider them during operation. Hub diameters should be calculated using specified formulas, and non-ferrous materials should be used cautiously due to potential changes in friction coefficients.
