Nominal Torque at Existing Run Out [0.2] T.I.R. (A) - 160 Nm
Nominal Torque at Existing Run Out [0.3] T.I.R. (A) - 150 Nm
Sprag Lift-off at Inner Ring Speed - 860 RPM
Maximum Speed of Inner Ring Freewheels/ Overruns - 5000 RPM
Maximum Speed of Outer Ring Drives - 224 RPM
Other salient points to be noted:
* Keyway according to DIN 6885
The maximum transmissible torque is 2 times the specified nominal torque
The theoretical nominal torque applies only for ideal concentricity between the inner and outer ring
Features:
• Sprag freewheels without bearing support, equipped with sprag lift-off X)
• Sprag lift-off X allows wear-free freewheeling when the inner ring rotates at high speeds
• The outer ring is pressed into the customer’s housing, enabling a compact and space-efficient design
• Nominal torque capacity: Up to 20,500 Nm
• Bore sizes: Available up to 130 mm
Application as:
• Backstop (For application as backstop in installations with high speeds in freewheeling operation)
• Overrunning Clutch (For application as overrunning clutch in instal- lations with low speeds in driving operation)
Mounting:
• Concentric alignment of the inner and outer rings must be ensured by the customer
• The permissible run out (T.I.R.) must be strictly followed for proper functioning
• Torque is transmitted via press fit on the outer ring
• The outer ring must be installed in a housing with external diameter K as per specification
• Housing material must be steel or grey cast iron (minimum grade GG-20)
• For other materials or smaller diameters, consult the manufacturer regarding torque capacity
• Shaft tolerance must be ISO h6 or j6
