Technical Features
U-yoke is die-forged to align grain flow with load direction, maximizing resistance to bending and fatigue cracking.
Deep quenching refines the steel microstructure, achieving a hard wear surface while retaining a tough core to absorb shock loads.
Precision CNC boring ensures concentric pin holes, preventing uneven stress distribution during track adjustment.
Applications
- Open-pit mining operations
- Road and highway construction
- Quarry and aggregate handling
- Demolition and site clearing
- Forestry and land management
Frequently Asked Questions
What is the MOQ for Case U-yokes?
Standard MOQ is 10 pieces per specification. Trial orders and sample requests are accepted for quality verification.
What is the delivery time?
Regular orders ship within 15–25 days after deposit. Stock models can ship within 7–10 days.
How deep is the heat treatment?
Heat treatment penetration is controlled to 3–6 mm with surface hardness HRC 50–55, depending on part size and application.
What warranty is provided?
We provide a 12-month warranty against material defects and manufacturing faults under normal operating conditions.
Can you match my OEM part number?
Yes. Provide your Case part number or drawing; we cross-reference dimensions and confirm equivalent before production.
Are U-yokes supplied as a kit with bushes and seals?
We supply bare U-yokes or complete kits including pins, bushings, and seals according to order requirements.
Maintenance Guide
- Installation: Verify pin bore dimensions and clean mounting surfaces before installation to prevent misalignment and premature wear.
- Lubrication: Apply recommended grease to pin joints during assembly; follow OEM lubrication intervals for track adjuster components.
- Inspection: Check U-yoke for cracks, deformation, or pin wear every 500 operating hours or during undercarriage maintenance.
- Replacement: Replace U-yoke if bore elongation exceeds OEM tolerance or visible cracks appear; never weld damaged forged components.
