Other salient points to be noted:
• The maximum transmissible torque is 2 times the specified nominal torque
• An oil lubrication of the specified quality must be provided
• Keyway connection on the outer ring with rollers
• Keyway according to DIN 6885
Features:
• Internal Freewheels FN are roller freewheels supplied without bearing support
• The freewheel is designed to be integrated into the customer housing, enabling compact and space-saving installation
• Capable of handling nominal torques up to 3,000 Nm
• Both faces of the outer ring are equipped with grooves for effective torque transmission
• Available with bores up to 60 mm
Application as: Backstop, Overrunning Clutch, Indexing Freewheel
Application Example:
• Internal Freewheel FN 20 is used as a backstop on the drive shaft of the running gears of a chain conveyor
• During normal operation, the drive shaft powers the system while the freewheel operates in freewheeling mode
• The freewheel functions as a backstop, preventing the running gears from rolling backward uncontrollably in the event of a fault or power failure
Mounting:
• Internal Freewheels FN are supplied without bearing support
• The customer must ensure concentric alignment of both the inner ring and outer ring
• The housing bore tolerance (D) must conform to ISO H7 or G7 standards
• The shaft tolerance must comply with ISO h6 or j6
• The outer ring must be completely enclosed within a rigid, stable housing to safely transmit the specified torques
Lubrication:
• An oil lubrication of the specified quality must be provided
