Samsung U-Yoke is a forged steel bracket securing track rollers to excavator undercarriage frames, maintaining correct track alignment and load distribution.
We offer factory-direct replacement U-yokes with complete OEM manufacturing services for global equipment distributors, rental fleets, and construction enterprises.
Our U-yoke resists bending, cracking, and premature bore wear, preventing track misalignment and costly undercarriage downtime in demanding mining applications.
With over 20 years of undercarriage component experience, Dingtai holds ISO9001 and SGS certifications, ensuring consistent dimensional accuracy and metallurgical reliability.
Each yoke uses 35MnB steel and deep quenching heat treatment to achieve high surface hardness while retaining a tough core for impact resistance.
Core Selling Points
- Premium 35MnB Material: Forged 35MnB boron steel provides high tensile strength, resisting bending and fatigue under extreme excavator loads and shock conditions.
- Deep Quenching/Heat Treatment: Induction-hardened bores and contact surfaces reach HRC 50-58, significantly reducing deformation and extending service life in abrasive undercarriage applications.
- OEM Capabilities: We match original Samsung drawings, part numbers, and mounting dimensions for direct drop-in replacement without field modification or special tooling.
- 100% QC Inspection: Every yoke undergoes dimensional checks, magnetic particle testing, and hardness verification before shipment to prevent hidden metallurgical defects and fitment issues.
Our catalog of Samsung U-Yoke includes various specifications, fully compatible with Samsung excavators and bulldozers.

Technical Features
The U-yoke is forged as a single-piece bracket, eliminating weld seams and stress risers. This monolithic structure improves fatigue resistance under cyclic loading.
Induction hardening creates high-hardness pin bore surfaces while the surrounding steel remains ductile, preventing brittle fracture under shock loads and extending wear life.
CNC boring and honing hold bore tolerances within 0.02 mm, ensuring interference-free pin rotation and consistent track roller alignment in demanding conditions.
Applications
- Mining operations with abrasive rock and heavy bucket loads
- Road construction and earthmoving projects
- Quarrying and aggregate handling
- Demolition and heavy civil applications
- Forestry and land clearing
Frequently Asked Questions
A: Stock-size U-yokes have an MOQ of 10 pieces; custom OEM orders may require 50 pieces depending on tooling.
A: Standard orders ship 15-30 days after deposit or drawing approval, depending on quantity and customization.
A: Effective case depth is 3-6 mm on pin bores and contact faces, verified by hardness testing.
A: We provide 12 months or 2,000 operating hours warranty against manufacturing defects under normal use.
A: Yes. Provide the Samsung part number or original drawing, and our engineers match dimensions and bolt patterns exactly.
A: Yes, stock models can be sampled. Custom U-yokes may require tooling investment before sample production.
A: Provide the machine model, serial number, or old part drawing. We verify compatibility before production.
Maintenance Guide
- Before installation, clean all mounting surfaces and inspect pin bores for burrs, cracks, or deformation that may affect fit.
- Torque mounting bolts to Samsung specifications and re-torque after the first 50 operating hours to prevent loosening.
- Grease pin bosses at recommended intervals to prevent dry metal contact and avoid premature bore elongation.
- Inspect U-yoke for cracks, elongated bores, or track misalignment every 500 operating hours during routine maintenance.
- Replace U-yokes in matched pairs when bore wear exceeds OEM tolerance to maintain equal track loading and alignment.
