🔧 Spicer 2040 Series Output Flange – Serrated / Cross-Serration
📌 General Description
An output flange for the Spicer 2040 series driveshaft and companion flange system, designed to provide a strong, vibration-resistant coupling between the driveshaft and transmission / differential. The flange uses cross-serrated (also called serrated or XS) profiles conforming to ISO serration standards to ensure positive mechanical engagement with the mating flange or yoke.
⚙️ Key Technical Data
• Series: Spicer 2040
Part of the Spicer Compact™ / Compact™ Series driveshaft range, with a functional torque capacity around 14,000 Nm (i.e., the series rated torque) — higher torque variations available with suffix variants in the 2040 range.• Flange Diameter:
Typical flange face diameter for 2040 driveshaft flanges is ≈ 155 mm to 180 mm depending on the exact flange specification and intended driveline connection.
• Connection Type:
Cross serration (XS) per ISO serration standards — this serrated pattern on the flange face provides enhanced grip and reduced micro-slip between mating driveline components.
• ISO Standards:
Serrated flanges usually adhere to ISO 8667 (cross serration) for flange faces and ISO 12667 for flange yokes — ensuring compatibility with standardized companion flanges.
• Typical Usage:
Connects the driveshaft to a companion flange / yoke on a transmission output or differential input in heavy-duty truck and off-highway drivetrain systems.
Designed so the serrations interlock and transmit high torque while limiting vibration and fretting.
