Product Description

The precision 20x27x4 bearings, engineered for high-accuracy applications, feature compact dimensions of 20mm bore, 27mm outer diameter, and 4mm thickness. These thin-section 20x27x4 ball bearings optimize space-critical designs while delivering low-friction operation and radial load support. Operating within a temperature range of -30°C to +120°C, they withstand industrial environments such as robotics, medical devices, and aerospace systems. Constructed with chrome steel races and precision-ground surfaces, the 20x27x4 ball bearings achieve ABEC-1 or higher tolerance standards. Advantages include reduced weight, minimized rotational inertia, and compatibility with tight axial spaces, though limited axial load capacity requires supplemental support in high-stress scenarios. These bearings enable precise motion control in servo motors, optical equipment, and miniaturized automation platforms.
