Detailed Description

The 17A-71-12352 LOCK KOMATSU is not just another small part—it’s a fundamental piece of your Komatsu equipment’s mechanical integrity. Designed in a semi-circular or “half-moon” shape, this lock fits tightly against shafts, flanges, or rotary interfaces, preventing unwanted movement or mechanical disengagement during high-vibration or high-load scenarios.

Its thick steel construction and CNC-milled profile make it exceptionally stable under load. The part features four evenly spaced mounting holes, ensuring perfect alignment with your Komatsu equipment’s original architecture. Once bolted, it serves as a rigid securing element that can withstand the torque generated by hydraulic systems, drivetrain movement, or articulated joints.

The 17A-71-12352 LOCK KOMATSU is treated with an anti-corrosive surface finish, giving it longevity in moisture-prone, dusty, or chemically active job sites. It also provides excellent resistance to cracking, chipping, or deformation even after years of use. This makes it a trusted component for maintenance and repair of Komatsu machines in sectors such as construction, demolition, road building, and quarrying.

When precision and safety matter, this lock plate is a must-have for fleet managers and maintenance professionals who demand OEM-quality without compromise.
