Use of Steel Bright Bars in Track Pin Manufacturing
A track pin is a critical connecting component used in crawler
excavators, bulldozers and other tracked heavy equipment. It joins
track links and allows smooth movement over rough terrain.
To manufacture track pins, steel bright bars are used as raw
material due to their high shear strength, wear resistance and
dimensional accuracy. These properties ensure long service life
under extreme load and abrasive conditions.

Applications of Track Pins
- Excavators
- Bulldozers
- Crawler loaders
- Tracked cranes
- Mining equipment
Why Bright Bars Are Used to Manufacture Track Pins
- High shear and tensile strength
- Excellent wear resistance
- Tight dimensional tolerance
- Uniform mechanical properties
- Good machinability for chamfers and grooves
Track Pin – Typical Geometry & Machined Features
Track pins typically include hardened wear surfaces,
precision press-fit zones and chamfered edges
for smooth assembly and long operational life.
Track Pin Manufacturing Process Using Bright Bars
- Cutting bright bars to length
- CNC turning
- Machining press-fit areas
- Induction hardening or heat treatment
- Grinding for tolerance
- Surface coating (optional)
Steel Grades Commonly Used for Track Pins
| Application | Steel Grade | Reason |
|---|---|---|
| Standard earthmoving | EN8, C45 | Good strength and cost balance |
| Heavy-duty mining | EN19 | High fatigue resistance |
| Extreme load conditions | 42CrMo4 | Superior toughness |
Common Track Pin Failures
- Surface wear from abrasion
- Bending under overload
- Cracking from fatigue
- Improper heat treatment failures
Using high-quality bright bars with controlled metallurgy
significantly reduces these failures.
