F long pin
Key Design Features:
1. Precision Spline Engagement
Hardened Spline Profile – Precision-machined splines (HRC 58-62) ensure zero-backlash torque transmission and smooth sliding action
Multiple Spline Standards – Available in DIN, SAE, JIS, or custom profiles to match your driveline requirements
High-Torque Capacity – Optimized involute or straight spline geometry for maximum load distribution and minimal stress concentration
Corrosion-Resistant Surface – Phosphated, coated, or nitrided splines prevent rust and ensure smooth operation over extended service life
2. Integrated Yoke Configuration
Telescopic Length Adjustment – Internal spline design allows axial movement for driveline length compensation and misalignment absorption
Solid Forged Construction – One-piece yoke body manufactured from 20CrMnTi or 20Cr alloy steel for superior strength
Multiple End Connections – Choose from flange, welded, or splined end fittings to suit various assembly requirements
Precision Bore Machining – CNC-machined bearing seats ensure perfect cross journal alignment and extended bearing life
3. Superior Torque Transmission
Precision-ground cross journal with hardened bearing surfaces (HRC 58-62)
Needle roller bearings with high load capacity and low friction
Operating angles up to 25°-30° (single joint), 40°+ with double joint configuration
4. Industrial-Grade Durability
Yoke body, cross and bearing caps manufactured from 20CrMnTi or 20Cr alloy steel
Carburizing and hardening heat treatment for wear resistance
Sealed grease lubrication with multi-lip nitrile rubber seals
Corrosion-resistant coating options: black oxide, zinc plating, or phosphating
5. Versatile Configuration Options
Sliding Spline Yoke – For applications requiring axial movement and length adjustment
Fixed Spline Yoke – For rigid connections with precise torque transmission
Double Yoke Assembly – For parallel offset or high-angle applications
Combination Designs – Spline yoke paired with flange or welded yoke ends
