Product Description

The Φ2.5×4mm Compression Spring is a precision-engineered component designed for compact mechanical systems, offering a compression load capacity of 0.5-5N with stainless steel or music wire construction. Its 2.5mm outer diameter and 4mm free length ensure compatibility with tight spaces in automotive, robotics, and aerospace assemblies. Paired with the Φ2.5×4mm Metal Spacer, which provides 0.2mm radial tolerance for precise shaft alignment, this combination delivers vibration resistance across -40°C to +120°C operating temperatures. The Φ2.5x4 Precision Washer complements these components with ±0.01mm thickness tolerance, ideal for surface protection in high-torque applications. While optimized for durability, the system requires controlled installation torque (max 2.5Nm) to prevent deformation. Primary applications include servo motor assemblies, miniature valve systems, and optical device stabilization mechanisms where space constraints demand submillimeter accuracy.
