Product catalog summary
Application Example: The document describes the use of two Complete Freewheels FB 82 SFT as overrunning clutches in the drive of an edge trimming shear in a wide strip roll train. These freewheels operate in driving mode when trimming rollers are driven and switch to freewheeling mode when the strip is pulled by the next pair of rollers. The RIDUVIT® sprags enhance the service life of the freewheels.
Product Features: Complete Freewheels FB are sealed sprag freewheels with ball bearings, supplied oil-filled and ready for installation. They are available in four types, including a standard type and three others for extended service life. They can function as a Backstop, Overrunning Clutch, or Indexing Freewheel. Nominal torques reach up to 160,000 Nm, with bores up to 300 mm.
Mounting Instructions: The customer attachment part is mounted on the external diameter D and bolted to the face. Shaft tolerance must be ISO h6 or j6, and the pilot diameter D of the attachment part must be ISO H7 or J7.
Ordering Information: When ordering, specify the freewheel size, type, and bore. For sizes FB 340 and FB 440, also specify the freewheeling direction of the inner ring (counterclockwise or clockwise).
Technical Specifications: The document includes a detailed table listing various freewheel sizes (FB 24 to FB 440), their bore diameters, nominal torques, maximum speeds, and other specifications. It highlights that freewheels with certain bore diameters are available with short delivery times.
Types of Freewheels: The document outlines four types of freewheels: Standard type for universal use, Type with RIDUVIT® for extended service life, Type with sprag lift-off X for high-speed rotating inner rings, and Type with sprag lift-off Z for high-speed rotating outer rings.
Additional Notes: The maximum transmissible torque is twice the specified nominal torque. Keyway specifications are according to DIN 6885, with specific tolerances for keyway width.

Type with sprag lift-off X Application example Two Complete Freewheels FB 82 SFT as overrunning clutches in the drive of an edge trimming shear in a wide strip roll train. When trimming the edges of the strip, the trimming rollers are driven by the drive of the edge trimming shear. By doing so, the two freewheels work in driving operation. As soon as the sheet metal strip is gripped by the next pair of rollers, they pull the strip at an increased speed and the inner rings overrun the slower turning drive of the edge trimming shear. By doing so, the freewheels work in freewheeling operation. The RIDUVIT® sprags give the freewheels an extended service life. The customer attachment part is on the external diameter D and then bolted on to the face. The tolerance of the shaft must be ISO h6 or j6 and the tolerance of the pilot diameter D of the attachment part must be ISO H7 or J7.
