Dimension (O) - 205 mm
Dimension (R) - 425 mm
Dimension (S) - 196 mm
Dimension (T) - 473 mm
Minimum Dimension (U) *** - 250 mm
Maximum Dimension (U) *** - 425 mm
Dimension (V) - 36 mm
Number of Fastening Holes (Z) ** - 6 mm
Weight - 197 kg
Slipping Toeque (MR) - 19000 Nm
Sprag Lift-off at Inner Ring Speed - 250 RPM
Maximum Speed Inner Ring Freewheels - 2700 RPM
Other salient points to be noted:
* Keyway according to DIN 6885
** Z = Number of fastening holes for screws G on pitch circle T
*** Area for O-ring sealing
Features:
• Integrated Freewheels FXR are sprag-type freewheels without built-in bearing support, featuring sprag lift-off design (X)
• The sprag lift-off mechanism ensures no contact during high-speed inner ring rotation, resulting in wear-free operation
• Upon stoppage, the full backdriving torque often gets concentrated on a single backstop, which can overload it
Application as: Backstop (For continuous conveyor systems that use multiple drives, each fitted with its own backstop)
Torques:
• IIntegrated Freewheels FXRU are equipped with a preset slipping torque (MR) for the built-in torque limiter
• The static backdriving torque (ML) of the installation, even under overload conditions — must never exceed the combined MR values of all installed freewheels
Mounting:
• Integrated Freewheels FXRU do not have bearing support
• The runout (T.I.R.) between the pilot diameter (R) and shaft diameter (d) must not exceed 0.25 mm
• Dimension C is the reference depth for the freewheel installation
• The centering depth of the customer’s attachment part must be at least C + 0.2 mm
• The pilot diameter R must have a tolerance of ISO H7
• The shaft diameter must conform to ISO h6 or j6 tolerance
