Product Description

The 5x8x2.5 precision bearing is a compact, high-performance component engineered for demanding industrial applications such as robotics, automotive systems, and precision machinery. Featuring a 5x8x2.5 metric needle roller design, it delivers exceptional radial load capacity and smooth rotation under speeds up to 12,000 RPM. This ABEC5-rated bushing supports direct integration with servo motors, linear guides, or gearboxes, operating within a temperature range of -30°C to +120°C and requiring minimal lubrication. Its hardened steel construction ensures durability in harsh environments, while the ultra-low friction design enhances energy efficiency. Though optimized for compact spaces, its small size limits axial load handling. Ideal for CNC equipment and automation systems, this bearing balances precision tolerances (±0.002mm) with robust performance in high-vibration settings.
