Key Features

Superior Strength: Made from Grade 8.8 steel, these bolts can withstand tensile loads up to 80 kN and yield loads up to 64 kN. This ensures they can handle the intense stress and strain encountered during excavator operations, reducing the risk of breakage and failure.

Corrosion Resistance: The black oxide coating provides an extra layer of protection against corrosion. This is particularly beneficial for equipment used in harsh environments where exposure to moisture, chemicals, and dirt is common. The stainless steel material further enhances the bolt and nut's ability to resist rust and corrosion, prolonging their service life.

Precision Fit: Manufactured to exacting standards, the No. 303 - 9441 Hex Bolt is specifically designed to fit Caterpillar excavator components. Its precise dimensions and threading ensure a secure and reliable connection, minimizing play and wear on connected parts.

Applications

These bolts and nuts are ideal for various applications on Caterpillar excavators, including but not limited to:

Securing attachment points for buckets, blades, and other excavation tools.

Fastening undercarriage components such as tracks, rollers, and idlers.

Mounting engine and hydraulic system parts.

Installation and Maintenance

Installation: Always follow the manufacturer's recommended torque specifications when installing these bolts and nuts. Using a torque wrench is essential to ensure proper clamping force is applied, preventing overtightening or undertightening.

Maintenance: Regularly inspect the bolts and nuts for signs of wear, corrosion, or looseness. Clean them with an appropriate solvent to remove dirt and debris. If any damage or excessive wear is detected, replace them immediately to maintain the safety and reliability of your excavator.

It mainly consists of tracks, drive sprockets, idler wheels, rollers and carrier rollers and other components. The track is looped between the drive sprocket and the idler wheel. The drive sprocket transmits power to the track through meshing with it, enabling the vehicle to move forward or backward. The rollers are evenly distributed above the track and bear most of the vehicle's weight to ensure the vehicle's stability during driving. The carrier rollers mainly serve to support the upper part of the track and prevent it from sagging too much.
