Product Description

The 8x12x3.5 precision bearing is a compact, high-performance miniature ball bearing designed for demanding applications requiring minimal tolerance deviations. With dimensions 8mm (ID) x 12mm (OD) x 3.5mm (width), this stainless steel 8x12x3.5 ball bearing operates at speeds up to 20,000 RPM while maintaining radial loads of 120N. It features shielded design for contamination resistance and temperature stability from -30°C to 120°C. Ideal for robotics, medical devices, and drones, the 8x12x3.5 precision bearing offers low-noise operation with ABEC-5 grade accuracy. Its compact profile enables integration in space-constrained mechanisms, though prolonged extreme-load use may require lubrication. Compatible with miniature motor assemblies and linear motion systems, it supports direct mounting in aluminum/steel housings via press-fit installation. Typical applications include optical encoders, micro-drive systems, and CNC tooling components demanding micron-level precision.
