Product Description

The 4x8x3 High Precision Component is a compact micrometric bearing designed for critical applications demanding ultra-tight tolerances, achieving ABEC-7 grade accuracy. This high-precision device features 4 digital input channels, 8 analog output terminals, and 3 direct modular interfaces supporting industrial communication protocols like CAN bus and RS-485. Operating within 5-36VDC and -40°C to +120°C, it excels in aerospace instrumentation, medical robotics, and semiconductor manufacturing. The 4x8x3 micrometric bearing's ceramic hybrid construction enables frictionless rotation with positional accuracy down to ±0.001mm, paired with integrated optical sensors offering 15mm detection range. While requiring precise thermal compensation in extreme conditions, its gold-plated contacts and shielded EMI protection ensure reliable signal integrity. The component excludes onboard power storage, prioritizing pure mechanical precision through its vacuum-sealed raceway design optimized for high-RPM microactuator systems.
