DEVELON / DOOSAN Lock Washer | Genuine Construction Machinery Component for Secure Fastening Systems
DESCRIPTION
PRODUCTS DESCRIPTION
The DEVELON / DOOSAN genuine lock washer is engineered to maintain bolt preload integrity in high-vibration construction environments. Designed to meet original equipment specifications used across DEVELON (formerly DOOSAN Infracore) machinery platforms, this locking component enhances joint stability by preventing rotational loosening under dynamic loads. Manufactured with precision-controlled spring characteristics and hardened surface treatment, it ensures consistent clamping force retention in structural assemblies such as undercarriage systems, hydraulic mounting points, and powertrain connections.
Built in accordance with OEM fastening system standards, this lock washer is compatible with designated DEVELON / DOOSAN equipment models and supports long-term operational reliability in heavy-duty applications including excavation, material handling, and earthmoving. Each unit undergoes dimensional tolerance verification and material hardness inspection to guarantee fit accuracy and structural durability. Using genuine components reduces maintenance risk, protects threaded assemblies, and supports optimal lifecycle performance of critical mechanical joints.
