Description of Suffix:
R - Standard Type for Universal Use
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 BM are sealed freewheels equipped with ball bearings
• In addition to the standard version, a variant with sprag lift-off (type X) is offered for wear-free freewheeling when the inner ring rotates at high speed
• Designed to handle nominal torques up to 57,500 Nm
• Available with bores up to 150 mm
Application as: Backstop, Overrunning Clutch, Indexing Freewheel
Application Example:
• The freewheel operates without radial seal rings and is lubricated by the gearbox oil
• A radial holding pin engages with the outer ring’s keyway
• The backdriving torque is absorbed by the holding pin mounted in the stationary housing
Mounting:
• The shaft tolerance must conform to ISO h6 or j6
• The pilot diameter D of the attachment part must comply with ISO H7 or J7
