Gear Yoke for PTO Shaft
The Gear Yoke (involute spline yoke) is a high-performance PTO end yoke with an internal gear-tooth profile bore. This involute spline connection provides maximum torque capacity and eliminates backlash, making it the preferred choice for heavy-duty PTO drivelines. Spanning series 2G through 50G with bore diameters from 23.8 to 50 mm, it serves agricultural balers to industrial pump drives. CNC-hobbed from forged alloy steel with case-hardened teeth, each gear yoke delivers precise engagement and extended operational life.
Gear Yoke for PTO Shaft – Involute Spline High-Torque Driveline Connector
Gear-tooth profile yoke | Series 2G–50G | 23.8–50 mm bore | involute spline
The Ever-power Gear Yoke utilises an involute gear-tooth bore profile that interlocks with matching gear-form PTO tubes to achieve the highest torque density of any yoke type. The gear-tooth engagement distributes load across dozens of contact points, virtually eliminating backlash. Forged from 20CrMnTi alloy steel, gear-hobbed on CNC machines, and carburised to 58–62 HRC.

⭐ Key Features & Benefits
⚙️
Involute Gear-Tooth Bore
Gear-hobbed profile distributes torque across many teeth simultaneously.
💪
20CrMnTi Alloy Steel
Carburising-grade alloy with hard surface (58–62 HRC) and ductile core.
🔄
Zero Backlash
Precision gear mesh eliminates angular play for consistent rotational timing.
🔧
Wide Torque Range
From Series 2G (light) to 50G (industrial), scaling to any torque requirement.
💧
Oil-Bath Compatible
Surface finish supports oil-bath or grease-packed driveline housings.
🔄 Compatibility Information
Designed for gear-form (involute spline) PTO tubes. Compatible with Bondioli & Pavesi, Walterscheid, Comer, and OEM drivelines using gear-tooth profiles. Suitable for round balers, forage harvesters, large slashers, generators, and pump drives.
📚 Selection Guide
Step 1: Count teeth and measure pitch diameter to identify series.
Step 2: Cross-reference bore (A), width (B), length (D) in the table.
Step 3: Select .06G (standard) or .07G (compact).
Step 4: Verify tooth module and pressure angle compatibility.
🌾 Typical Application Scenarios
🌾 Forage Harvesters
Manages extreme torque loads in harvesting operations.
💾 Industrial Pump Drives
Smooth, backlash-free power to hydraulic and water pumps.
🌳 Heavy-Duty Chippers
Handles shock loads from feeding logs into large chippers.
⚡ Generator Drives
Consistent rotational input for PTO-driven generators.
🛠️ Installation & Usage Guide
Verify gear tooth count and module of both yoke and PTO tube.
Clean all gear teeth with solvent; inspect for burrs.
Lightly oil gear teeth with ISO 220 gear oil before meshing.
Align and slide together — teeth should engage smoothly.
Install cross kit ensuring bearing caps seat fully.
Apply grease, run at idle speed, and check for vibration.
