Dimension (D) - 47 mm
Dimension (K) - 60 mm
Weight - 0.1 kg
Type - Standard Type for Universal Use
Nominal Torque (MN) - 48 Nm
Maximum Speed for Inner Ring Freewheels/ Overruns - 2900 RPM
Maximum Speed for Outer Ring Freewheels/ Overruns - 3050 RPM
Description of Suffix:
CFH - Standard Type for Universal Use
Other salient points to be noted:
• The maximum transmissible torque is 2 times the specified nominal torque
• The maximum speed values listed above apply to installation conditions as they are given for Complete Freewheels. If the actual installation conditions are known, higher speeds may be permitted under certain circumstances
Features:
• Internal Freewheels FDN are sprag freewheels with anti-friction bearing dimensions
• Designed to handle nominal torques up to 2,400 Nm
• The torque is transmitted via a press fit on the outer ring
• Available with bores up to 80 mm
Application as: Backstop, Overrunning Clutch, Indexing Freewheel
Application Example:
• Internal Freewheel FDN 40 CFR (standard type with bearing support) is used as an overrunning clutch on the shaft end of the main drive in a textile machine
• During normal operation (freewheeling mode), the inner ring overruns while the gear wheel and outer ring remain stationary
• During setup, the machine is driven at low speed by the auxiliary drive, which transmits motion via the gear wheel and the freewheel operating in driving mode
Mounting:
• Internal Freewheels FDN (standard type) are supplied without bearing support
• The permissible runout (T.I.R.) must be strictly observed to ensure correct operation
• To achieve the specified torque ratings, the outer ring must be installed in a housing with external diameter K
• The housing should be made of steel or grey cast iron, with a minimum grade of GG-20
• The housing bore tolerance (D) must comply with ISO P6
• The shaft tolerance must comply with ISO h6 or j6
• The permissible operating temperature range for the freewheel is -40 °C to +80 °C
Lubrication:
• An oil lubrication of the specified quality must be provided
