Maximum Bore Diameter (d) * - 50 mm
Outer Diameter (D) - 135 mm
Dimension (F) - 2 mm
Thread (G) ** - M10
Dimension (H) - 16 mm
Dimension (L) - 75 mm
Dimension (T) - 115 mm
Number of Tapped Holes (Z) ** - 12
Weight - 5.8 kg
Type - Standard Type for Universal Use (SF Type)
Nominal Torque (MN) - 1800 Nm
Maximum Speed of Inner Ring Freewheels/ Overruns - 1025 RPM
Maximum Speed of Outer Ring Freewheels/ Overruns - 1450 RPM
Description of Suffix:
SF - Standard Type for Universal Use (SF Type)
Other salient points to be noted:
* Keyway according to DIN 6885
** Z = Number of tapped holes G on pitch circle T
• The maximum transmissible torque is 2 times the specified nominal torque
• Tolerance of keyway width JS10
Features:
• Type: sealed sprag freewheels with integrated ball bearings
• Lubrication: supplied oil-filled and ready for installation
• Eco Option: Available with biodegradable oil upon request
• Variants: Standard model, three enhanced versions designed for extended service life and reliable performance in demanding applications
• Nominal torque capacity up to 160,000 Nm
• Bore sizes up to 300 mm
• A wide selection of standardized bore diameters is available, ensuring short lead times and fast delivery
Application as: Backstop, Overrunning Clutch, Indexing Freewheel
Application Example:
• During edge trimming, the trimming rollers are powered by the shear’s drive, operating the freewheels in driving mode
• When the next pair of rollers grips the sheet metal strip and pulls it at a higher speed, the inner rings of the freewheels overrun the slower shear drive
• At this stage, the freewheels operate in freewheeling mode
• The use of RIDUVIT® sprags significantly extends the service life of the freewheels
Mounting:
• The customer attachment part is mounted on the external diameter (D)
• The attachment is then bolted to the face
• The shaft tolerance must conform to ISO h6 or j6
• The pilot diameter (D) of the attachment part must have a tolerance of ISO H7 or J7
