Frequently Asked Questions
Q
What grade steel are HeSen Track Roller Bolts made from?
HeSen Track Roller Bolts are manufactured from premium alloy steel at Grade 10.9 or 8.8, which provides high tensile strength and resistance to shearing or deformation under heavy operational loads.
Q
Which excavator and machinery brands are these bolts compatible with?
These track roller bolts are compatible with major brands including Komatsu, Caterpillar (CAT), Hitachi, Kobelco, Volvo, and Hyundai, among others. They are also suitable for bulldozers and crawler cranes that use standard undercarriage track frames.
Q
How does the black oxide coating protect the bolts?
The black oxide coating creates a surface layer that significantly reduces moisture absorption and oxidation, providing strong protection against rust and corrosion. This makes the bolts reliable in muddy, wet, and chemically abrasive construction environments.
Q
Do these bolts meet OEM specifications?
Yes. Each bolt is machined to strict OEM dimensional tolerances, ensuring a seamless, drop-in fit for track rollers and idlers without any modification required during installation.
Q
What quality testing do HeSen fasteners undergo?
Every HeSen fastener is subjected to rigorous quality control processes including hardness testing, tensile strength verification, and dimensional accuracy inspection to ensure compliance with international standards and to meet the safety demands of heavy-duty machinery.
Q
Why is using the correct track roller bolt important for undercarriage maintenance?
Using the correct track roller bolt ensures adequate clamping force is maintained between the roller and the track frame. Incorrect or low-quality bolts can loosen under vibration, leading to accelerated wear, misalignment, or even complete undercarriage failure, resulting in costly downtime and repairs.
