Built-In Freewheels AS

Product catalog summary

Overview: The document provides technical specifications and installation guidelines for the Type AS built-in freewheels, which are roller type freewheels that are not bearing supported. Bearings are necessary to handle axial and radial loads, and lubrication and sealing must be provided during installation.

Specifications: The Type AS freewheels have nominal outside dimensions similar to series 62 ball bearings. The inner race is keyed to the shaft, except for the 6 mm bore size. The outer race has a positive R6 tolerance for a press fit in an H7 housing, which must be strong enough to prevent expansion after assembly. The design allows for an axial misalignment of ± S/2 between the inner and outer races.

Performance Data: The document includes a table listing various sizes of the AS type freewheels, detailing their overrunning speeds, weight, and drag torque. For example, the AS6 model has a maximum overrunning speed of 7500 min-1 and a drag torque of 0.18 Ncm.

Mounting Instructions: The mounting dimensions are identical to ball bearings series 62. Specific notes include that the AS6 model does not have a keyway, while sizes AS8-12 have keyways conforming to DIN 6885.1, and other sizes to DIN 6885.3. The document refers to additional mounting and maintenance instructions on pages 12 to 13.

Recommendations: It is recommended to refer to the selection pages 7 to 11 for further guidance on choosing the appropriate freewheel type. The document also notes that the inner race overruns and the outer race overruns, with specific maximum torque and speed values provided.

Catalog excerpts

Built-In Freewheels ype AS is a roller type freewheel non-bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation. Nominal outside dimensions are the same as series 62.. ball bearings. A typical arrangement is to install this type alongside a series 62 bearing within the same location tolerances, as shown on the following page. The inner race is keyed to the shaft (except 6 mm bore). The outer race has a positive R6 tolerance to give a press fit in a H7 housing. The outer housing must be strong enough to not expand after assembly. This design can accept an axial misalignment of inner and outer race of ± S/2.
