SKF 16004 Deep Groove Ball Bearing 20x42x12 mm

The SKF 16004 is a single-row deep groove ball bearing sized 20 x 42 x 8 mm, designed for precise radial support in compact assemblies. Its bore is 20 mm, outer diameter 42 mm, and width 8 mm, giving a compact footprint that fits many small motors, gearboxes, and electromechanical devices. As a fundamental radial bearing, the 16004 carries mostly radial loads with limited axial tolerance, enabling smooth rotation at a broad range of speeds while maintaining control of runout and efficiency. SKF’s 16004 is part of a broad family of standard metric bearings, offering reliable performance and cross-brand interchangeability for replacements in consumer appliances, hobby machinery, and light industrial equipment when the 20x42x8 mm size is required. For exact variant selection, verify whether your application requires an open, shielded, or sealed configuration within the SKF 16004 range, and consult the manufacturer’s catalog to confirm tolerances and internal clearance that match your assembly.
