Product Description

The 4x12x4 premium bearing is a high-precision industrial roller engineered for demanding applications in automation, machinery, and automotive systems. Featuring a compact 4x12x4mm (IDxODxL) design, this premium 4x12x4 needle roller supports radial loads up to 580N and operates within -30°C to +120°C. Its hardened steel construction ensures durability in high-speed environments (max 12,000 RPM) while maintaining low friction. Compatible with standard 4x12x4 industrial roller housings, it integrates seamlessly into conveyor systems, robotics, and precision gearboxes. Key advantages include extended service life, corrosion resistance, and vibration damping, though installation requires precise alignment.
