Внутренняя лепестковая шайба, толщина 5 мм Caterpillar 6311578

An Internal Tab Washer is a fastening support component used within enclosed assemblies to maintain the secure positioning of nuts, bolts, or shafts during operation. It features formed tabs that engage with corresponding slots or surfaces, creating a mechanical lock that restricts unintended rotation. This locking action supports stable assembly integrity when components are subjected to vibration, cyclic loading, or directional movement. The washer is positioned between fastened parts to ensure consistent contact pressure and reliable retention throughout operating cycles. Its internal tab design allows it to fit within confined spaces, making it suitable for compact assemblies where external locking options are limited. The washer contributes to long-term fastening reliability by maintaining alignment and reducing the chance of loosening over time. During installation, the tabs are engaged to hold the fastener in place, allowing predictable retention without relying on friction alone. This controlled locking function supports accurate torque retention and repeatable assembly results. The Internal Tab Washer is commonly used in gear housings, rotating assemblies, and internal mounting points where secure fastening is required. Its use supports orderly assembly layout, reduces maintenance interruptions, and helps preserve consistent mechanical positioning across extended operating periods.Attributes:• Prevents fastener rotation through internal tab engagement.• Maintains consistent clamping force during operation• Supports secure retention in enclosed assemblies.Applications: An Internal Tab Washer is installed inside mechanical assemblies, positioned between fasteners and internal components. It locks into place using its formed tabs to restrict movement, ensuring secure fastening and maintained alignment during continuous operation and repeated load cycles.
