6152-21-6590 Spacer Komatsu bulldozer spare parts

The Komatsu 6152-21-6590 spacer is a precision positioning and clearance adjustment component for Komatsu bulldozer engines, transmission mechanisms, or chassis systems. Manufactured strictly according to Komatsu’s original dimensions, precision, and process standards, it is suitable for harsh operating conditions involving heavy loads, strong vibrations, and high dust levels. Primarily used for clearance control, positioning support, and pressure distribution between components, it ensures assembly accuracy and smooth operation, making it a key standard component for bulldozer maintenance, repair, and overhaul.

The 6152-21-6590 spacer is made of high-strength alloy structural steel, undergoing precision machining, heat treatment, and full dimensional inspection. It boasts high internal and external diameter accuracy, uniform thickness, good flatness, high compressive strength, wear resistance, and non-deformation, allowing it to withstand long-term impacts and loads without damage. It fits tightly with shafts, bearings, housings, and other components, effectively eliminating abnormal clearances and reducing abnormal noises, uneven wear, and vibration.

This product strictly adheres to Komatsu’s original standards, boasting strong adaptability and high durability. It is widely applicable to harsh operating environments such as mining, infrastructure, and earthmoving projects, effectively improving equipment assembly accuracy and operational stability while reducing failure rates and maintenance costs.
