Product Description

The 4x7x2.5mm Precision Bearing is a compact component designed for high-accuracy applications in robotics, automation, and CNC machinery. With a 4x7x2.5mm sealed spacer design, it integrates directly into modular assemblies, supporting axial and radial loads up to 15N. Operable within a voltage range of 3.3-24V DC and a temperature tolerance of -40°C to +120°C, it ensures reliable performance in harsh environments. The High-Precision 4x7x2.5 Bushing variant minimizes friction, while the 4x7x2.5 Sealed Spacer enhances dust and moisture resistance. Its stainless steel construction offers durability and corrosion resistance, though installation requires precise alignment due to its small form factor. Widely used in medical devices and optical systems, this component excels in applications demanding micron-level precision and compact integration.
