SM 8-3/4 Shaft

The shaft is custom-engineered for specialized applications and non-standard requirements. Key Features:

• Replaceable gear ring at the pinion end
• Replaceable roll-end locking pin
• Splined hub at the roll end
• ±3-1/2"" axial travel to adjust roll position
• Roll-end thrust spring pack
• Carburized gearing

This optional shaft configuration features a replaceable gear ring at both the roll end and the drive end. The gear ring is connected to the adapter via a tight-fitting spline, using a flat root side fit engagement. The gear ring is held concentric with the adapter by precision-machined pilot surfaces at both ends of the spline engagement. If the gear ring is damaged for any reason, it can be replaced in significantly less time than it would take to replace a sleeve with an integral gear, and it is also much more cost-effective.

The shaft is custom-engineered for specialized applications and non-standard requirements. Key features:

• Replaceable gear components
• Splined hub
• Roll-end thrust spring pack
• Enlarged bore at the roll-end adapter
• Carburized gearing

• Provides maximum torque transmission under severe shock load conditions, while still operating effectively at relatively large misalignment angles.
• Gear components are manufactured from medium carbon steel and forged alloy steel, with heat-treated gear tooth surfaces. The hub gear teeth are fully crowned to ensure maximum torque transfer with minimal backlash.
• The one-piece molded lip seal is designed to operate under misalignment conditions, providing the most effective sealing performance: retaining lubricant inside and preventing the ingress of dust and contaminants from the outside.
• All shafts are designed so that the contact point of the thrust button lies precisely on the centerline of the gear mesh. This allows for ball-and-socket-type motion, rather than sliding motion that would occur if the contact point were located on the thrust plate.
