Komatsu D355 Series Bulldozers -195-33-11303

Core Features

Service Braking: Provides rapid and stable braking force under heavy loads, enabling smooth deceleration or emergency stopping of the machine and avoiding the risk of coasting.

Steering Braking: The single-sided brake band generates steering torque when activated, enabling small-radius steering and adapting to on-site operations and complex terrain changes.

Parking Lock: Locks the brake drum when the machine is parked, preventing the machine from rolling and ensuring parking safety.

Friction Buffering: The copper-based friction pads buffer impacts when in contact with the brake drum, reducing impact loads on the transmission system and protecting the gearbox and final drive components.

Product Advantages

Original Factory Precise Fit: Manufactured according to Komatsu original drawings, the steel back curvature, rivet hole positions, and mounting lug distance are perfectly matched to the D355's overall braking system, requiring no modification and providing seamless compatibility with the brake cylinder and brake drum after installation.

High Wear and High Temperature Resistance: The friction pads use a copper-based alloy formula containing tin, graphite, etc., with a friction coefficient ≥0.42 at room temperature and high temperature resistance up to 350℃, ensuring no heat fade during continuous braking. The steel back is made of 45# tempered steel, resistant to deformation and fatigue, with a service life of over 2500 hours.

Rapid Braking Response:The friction pads and steel back are bonded using a high-temperature vulcanization process, eliminating the risk of detachment. During braking, the contact area is ≥95%, resulting in fast and linear braking force transmission, improving operational controllability.

Low Maintenance Costs:Easy installation, no special tools required; uniform wear of the friction pads can be compensated for by adjusting the lever stroke, extending the replacement cycle and reducing downtime maintenance costs.

High adaptability to working conditions: It is suitable for heavy-duty and dusty working environments such as mines, water conservancy, and infrastructure. It is resistant to oil and moisture, and its braking performance is not affected by harsh working conditions.

Applicable Scene

Suitable for Komatsu D355 bulldozers in heavy-duty continuous operation scenarios such as mining stripping, large-scale infrastructure, land leveling, and water conservancy dams. Especially suitable for working conditions with high braking loads such as long downhill slopes and frequent turns. It is a key wear part to ensure the safety and efficiency of the whole machine. It is recommended to check and replace it at the same time as the brake drum and seals to improve the stability of the braking system.
