When it comes to excavator undercarriage parts, many people focus on big components like track chains, rollers, and sprockets. But here’s the truth — even the smallest parts like track bolts and roller bolts play a crucial role in the overall stability and performance of your equipment. The CHZ Track Bolts and Roller Bolts are designed to deliver unmatched durability, precision, and strength for all types of heavy machinery.

What Are Track Bolts and Roller Bolts?

Track bolts and roller bolts are essential fasteners used to secure undercarriage components such as track shoes, bottom rollers, and top rollers to the frame of excavators, bulldozers, and other tracked equipment.

They might look simple, but in reality, these bolts handle enormous loads, vibration, and constant impact during machine operation. A single loose or poor-quality bolt can cause misalignment, damage, or even machine downtime — and no one wants that.

That’s why choosing high-quality CHZ Track Bolts and Roller Bolts is so important if you want your machine to perform efficiently and safely for the long haul.

CHZ Track Bolts and Roller Bolts – Engineered for Strength

The CHZ Track Bolts and Roller Bolts are manufactured with premium-grade 40Cr, 35CrMo, or SCM435 alloy steel, ensuring superior tensile strength and wear resistance. These bolts undergo heat treatment, precision forging, and hardness testing, guaranteeing excellent performance even under the toughest working conditions.

Key advantages include:

• High Tensile Strength: Withstand high vibration and torque without breaking or loosening.

• Anti-Loosening Design: Precision thread fit and fine pitch threading to ensure tight fastening.

• Corrosion Resistance: Surface treated with black oxide, zinc plating, or phosphate coating for long-term protection.

• OEM Compatibility: Perfect fit for popular excavator brands like Komatsu, Caterpillar, Hitachi, Doosan, Hyundai, and Volvo.

• Custom Sizes Available: CHZ can produce standard and non-standard bolts according to customer drawings or specifications.

These features make CHZ bolts ideal for undercarriage systems, crawler machines, and construction equipment that operate in challenging environments.

Why Choose CHZ Track Bolts and Roller Bolts?

Let’s face it — not all bolts are created equal. Some might look strong but can’t handle high stress or corrosion. That’s where CHZ, a trusted China track bolt and roller bolt manufacturer, makes all the difference.

CHZ uses CNC machining centers, automatic threading machines, and controlled heat-treatment furnaces to ensure consistency and precision in every bolt. Every batch goes through strict inspection, including torque testing, metallographic analysis, and hardness testing, before leaving the factory.

With years of experience in manufacturing excavator undercarriage parts, CHZ guarantees stable quality, competitive price, and fast delivery — something every construction business values.

Besides, if you’re looking for bulk orders or custom OEM solutions, CHZ can fully support you with professional engineering assistance and flexible production schedules.

Applications of CHZ Track Bolts and Roller Bolts

The CHZ Track Bolts and Roller Bolts are widely used in:

• Excavators and Bulldozers – For attaching track shoes and rollers securely.

• Mining and Quarry Equipment – To endure heavy impact and high abrasion.

• Agricultural and Forestry Machinery – Reliable fastening under constant vibration.

• Crawler Cranes and Road Machines – Maintain structural integrity in motion.

Simply put, wherever strong fastening and reliability are needed, CHZ bolts deliver.

How to Maintain and Replace Excavator Bolts

Even the best bolts need regular inspection to avoid costly breakdowns. Here are a few quick tips:

1. Check Tightness Regularly: Loose bolts can cause damage to the track system.

2. Inspect for Wear and Rust: Replace any damaged or corroded bolts immediately.

3. Use Proper Torque: Over-tightening or under-tightening can lead to failure.

4. Apply Anti-Seize Lubricant: Helps with future maintenance and reduces friction.

It’s a small thing, but keeping up with bolt maintenance can save you a ton of trouble later.
