SF 8-3/8 Shaft

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 SL shaft is used in medium-torque applications requiring high misalignment compensation. This shaft is suitable for cases where frequent disassembly of drive components is not required. The Amerigear SF flexible shaft is similar to the parallel shaft configuration using flanged couplings (F Series), but the gear teeth are designed to accommodate greater misalignment. The teeth are heat-treated to enhance torque capacity, and a specially molded large-angle lip seal is used to ensure sealing performance under high misalignment conditions. Additionally, the SF Series offers a short-coupled version to suit space-constrained installations.

This configuration is commonly used in cases where diameter constraints prevent the use of a gear ring at the roll end. The hub shafts are interchangeable in this design. This option allows the adapter at the pinion end of the pinion shaft to remain in place when replacing the gear ring, making maintenance faster and more convenient.

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

• Quick disconnect at the roll end
• Induction-hardened gearing
