Plain Bore Yoke Type H-Pin Hole & Threaded Hole for PTO Shaft

The Plain Bore Yoke Type H-Pin Hole & Threaded Hole delivers the ultimate in plain bore shaft security by combining two independent retention mechanisms: a cross-drilled pin hole for primary rotational and axial locking, plus a threaded set screw hole for secondary backup retention. If either mechanism were to loosen individually, the other maintains the connection. This redundant approach is specified for safety-critical PTO applications, overhead equipment, and installations where yoke separation could cause equipment damage or personal injury.

Plain Bore Yoke Type H (Pin Hole & Threaded Hole) — Redundant Dual-Lock PTO Yoke for Safety-Critical Applications

Plain Bore Yoke Type H-Pin Hole & Threaded Hole for PTO Shaft

这 Plain Bore Yoke Type H-Pin Hole & Threaded Hole applies the engineering principle of redundancy to PTO shaft retention. In safety-critical applications — overhead PTO-driven equipment, public-area maintenance machinery, or high-value processing lines where unplanned downtime is catastrophic — relying on a single retention mechanism introduces unacceptable risk. Type H eliminates this risk by providing two completely independent locking methods: a roll pin and a set screw. Each is individually capable of maintaining the connection; together, they create a fail-safe system that requires simultaneous failure of both mechanisms for separation to occur.

⭐ 主要特点和优势

🛡 Redundant Dual-Lock System

Two independent retention mechanisms — even if one loosens, the other holds. True fail-safe engineering.

🔒 Roll Pin — Primary Lock

Cross-drilled pin provides positive rotational and axial retention as the primary mechanism.

🔧 Set Screw — Secondary Lock

Threaded set screw provides backup axial retention and anti-vibration security as the secondary mechanism.

⚖ Safety-Critical Rated

Specified for applications where yoke separation could cause equipment damage, environmental harm, or personal injury.

📐 Full Bore Range

Available in 20-45 mm bore sizes across Series 1-8, covering all standard implement shaft diameters.

💪 Same Premium Construction

Forged alloy steel, H7 bore, induction-hardened bearing areas — identical to all other types in our range.

🔄 兼容性信息

Fits cylindrical shafts with both cross-drilled pin hole and flat/dimple for set screw contact. For safety-critical applications across all equipment types. Specified by overhead crane PTO drives, public-area maintenance equipment manufacturers, and high-reliability industrial systems.

📚 选择指南

Specify Type H when: Your risk assessment identifies yoke separation as a high-consequence event — overhead equipment, public-area machinery, or high-value continuous production lines.

Inspection Protocol: Check both the pin AND the set screw at regular intervals. The dual-lock system is only fail-safe if both mechanisms are maintained.

选购指南

🌾 典型应用场景

⚖ Safety-Critical Equipment
Overhead PTO drives, equipment in public areas, automated processing lines
🔧 High-Reliability Industrial
Continuous production machinery where unplanned stops cost thousands per hour
💧 Hazardous Material Handling
Slurry pumps, chemical mixers, and equipment where separation could cause spills
🌾 Compliance-Driven Applications
Installations requiring documented dual-retention per safety audits

🛠 安装和使用指南

  1. Install primary pin: Seat the roll pin through both yoke and shaft pin holes.
  2. Install secondary set screw: Thread set screw with medium-strength thread lock and tighten against shaft.
  3. Verify both mechanisms: Attempt to rock and pull the yoke — no movement should be detected.
  4. Document installation: Record pin size, set screw torque, and date for maintenance tracking.
  5. Install cross kit: Complete PTO shaft assembly.
  6. Establish inspection schedule: Check both pin and set screw at intervals specified by your safety protocol.

❓ 常见问题解答

Is dual retention really necessary?
For safety-critical applications, yes. Redundancy is standard engineering practice in aerospace, automotive, and heavy industry. Type H applies this principle to PTO connections.
What are the failure modes each mechanism protects against?
The pin protects against rotational and primary axial failure. The set screw protects against axial creep from vibration. Each backs up the other.
How often should I inspect both mechanisms?
Depends on the application criticality. Minimum: check both every 50 operating hours. Safety-critical applications may require daily inspection.
Can I use Type H as a general-purpose yoke?
Yes — it works perfectly for any application. The dual retention adds security without adding complexity to installation.
Is Type H more expensive than single-retention types?
Slightly, due to the additional threaded hole machining. The safety margin easily justifies the small premium.
What thread-locking compound is recommended?
Medium-strength (Loctite 242 or equivalent). High-strength can make set screw removal difficult for inspection.
