Product Description

Fgk Internal Freewheels for Press Fit on The Outer Ring
Internal Freewheels FGK
for press fit on the outer ring
with sprags and bearing
 
Features
Internal Freewheels FGK are sprag freewheels with bearing support in the dimensions of the
needle bearing series 59. The freewheels are supplied grease-filled for normal operating
conditions and are maintenance-free. The outer ring is pressed into the customer housing. This makes compact, space-saving fitting solutions possible. The freewheels FGK are used as
 Backstops
 Overrunning Clutches
 Indexing Freewheels
Nominal torques up to 460 Nm. The torque is transmitted on the outer ring by press fit. Bores up to 50 mm.

Application example
Internal Freewheel FGK 35 as an indexing freewheel in a circular knitting machine. Set-up in order to change material or after breakdown requires a sensitive, manual adjustment of the
rotary table. Therefore the rotary table is moved per hand lever via the freewheel which is working in driving operation. After set-up, the drive is carried out via the main motor and the
freewheel outer ring overruns.
 
Mounting
The torque is transmitted on the inner and outer ring by press fit. In order to transmit the
torques specified in the table, the outer ring must be accommodated in a housing with an
external diameter K. The housing is made of steel or grey cast iron in minimum quality GG-
20. When using other housing materials or smaller external diameters, we urge you to contact
us regarding the transmissible torque. The tolerance of the housing bore D must be ISO R6 and the tolerance of the shaft must be ISO p5. With these fits, normal bearing clearance is achieved in a built-in state. The permissible operating temperature of the freewheel is - 40°C to 80°C.
 
Lubrication
The freewheels are supplied grease-filled for normal operating conditions. However, the
freewheels can also be connected to the customer's oil lubrication systeem; this is particularly
recommended in the case of higher speeds.
