CSK series
All the CSK versions are equipped with “formchromed” sprags. This process increases several times the overrunning life time. Torque transmission is ensured by a press fit assembly into a rigid outer housing with N6 tolerance, and onto a shaft with n6 tolerance. The initial bearing radial clearance is set at C5, and is reduced if using the press fit as specified.
Please contact us when either the ambient or the operating temperature is not within the range 5°C to 60°C. CSK..2RS is 5 mm wider but is equiped with lip seals to be water splash resistant.
Types CSK..P and CSK..PP are sprag type freewheels integrated into 62.. series ball bearings (except size 40). They are bearing supported, delivered grease lubricated and protected against dust of more than 0,3 mm.
The use of additional “nylos” type seals is recommended especially when the working temperature exceeds 50°C. Oil bath lubrication is also possible.
In addition to the basic CSK model, type CSK..P features a keyway on the inner race. For this reason it can be keyed to a shaft to k6 tolerance. The outer race must still be pressed into a rigid housing to N6 tolerance.
CSK..PP features a keyway on both the inner and outer race. The recommended mounting tolerances are h6 on the shaft and H6 in a rigid housing. Please contact us when either the ambient or the operating temperature is not within the range 5°C to 60°C.

ASNU series
Type ASNU 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 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.

DC series
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 power transmissions including gear oils with EP additives.
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.

FE series
FE series Freewheel-clutches transmit or support torque moment by friction contact in one direction and permit idling in the opposite direction.
USED AS:
1.Indexing elements to change from oscillating to intermittent rotary motion.
2.Backstops to prevent self reversing due to load condition when the machine is not activated.
3.Overrunning clutches to maintain driven unit activated even during slowdown, or in the case of
two speed operation (by independent motors) to switch to the higher speed by passing the slower.
LUBRICATION
Lubrication is especially important to obtain maximum life of freewheel clutches.
Good lubrication decreases drag. Please refer to our Lubrication Selection Table for proper
selection.
Clutches (except the sealed Clutches of series FND, FPD, FK 62...-RS, FK 62...-2RS, FKN...-RS , and FKN...-2RS) are shipped rust protected not lubricated.
