1、 Type 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.
2、 Type ASNU is a roller type freewheel nonbearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation. Nominal outer diameter is the same as a series 63...Ball bearing.
A typical arrangement is to install this type alongside a bearing within the same location tolerances, as shown on the following page. The inner race is keyed to the shaft.
The outer race has positive n6 tolerance, to give a press fit in a H7 housing. Additional side notches in the outer race provide for positive torque transmission.
If the housing is to K6 tolerance, use of the notches is not necessary, but the housing must be strong enough to not expand after assembly. This design can accept an axial misalignment of inner and uter race of ± S/2.
3、 CSK series one way freewheels are sprag freewheels with bearing support and ball bearing proper-ties. The freewheels are supplied grease-filled for normal operating conditions.
The freewheel is built into the customer housing. This makes compact, space-saving fitting solutions possible.
The freewheels CSK series are used as:
Backstops
Overrunning Clutches
Indexing Freewheels
Nominal torques up to 325 Nm. The torque is transmitted on the inner ring and/or on the outer ring by press fit or keyway connection. Bores up to 40 mm.
4、 Type DC is a sprag type freewheel cage without inner or outer races. It must be installed in a design providing races, bearing support for axial and radial loads, lubrication and sealing. The DC type version-N accepts all types of lubricants currently used in the power transmis-sion equipement.
The sprag space tolerance must not be exceeded. Inner and outer races must both have a minimum plain width "e", without any recess, to ensure the freewheel functions correctly as shown on following pages.
Alternatively, races can be made in case hardened steel shafts, or housings, to the specification below. Surface hardness of the finished part should be HRC 60 to 62, for a depth of 0, 6 mm minimum.
Core hardness to be HRC35 to 45. Surface roughness not to exceed 22CLA. Maximum taper between races: 0, 007 mm for 25 mm width.
