Other salient points to be noted:
• The maximum transmissible torque is 2 times the specified nominal torque
• Tolerance of keyway width JS10
• Keyway according to DIN 6885
Features:
• Complete Freewheels FGR … R A2A3 with lever arm are sealed roller freewheels equipped with ball bearings
• Designed to handle nominal torques up to 68,000 Nm
• Available with bores up to 150 mm
Application as: Backstop (for applications with low to medium speeds in freewheeling operation)
Application Example:
• Complete Freewheel FGR … R A2A3 is used as a backstop at the end of an inclined conveyor belt
• The backdriving torque is supported by a lever arm with a holding pin fixed to the base (fundament)
• When the holding pin is removed, the conveyor belt shaft can be rotated in both directions, allowing for maintenance or repositioning
Mounting:
• The holding pin should allow 0.5 to 2 mm of play in both axial and radial directions
• If the holding pin is removed, the shaft can be rotated freely in both directions
• The shaft tolerance must comply with ISO h6 or j6
