16004 2RS Deep Groove Ball Bearing
The 16004 is a narrow-section single-row deep groove ball bearing measuring 20 x 42 x 8 mm, engineered for designs where axial space and weight are critical. The ultra-thin cross-section cuts mass and frictional torque versus standard-series bearings of the same bore, while the deep raceway grooves still carry dependable radial and bidirectional axial loads, rated at 7.28 kN dynamic load.
Product Overview
The 16004 is a narrow-section single-row deep groove ball bearing measuring 20 x 42 x 8 mm, engineered for designs where axial space and weight are critical. The ultra-thin cross-section cuts mass and frictional torque versus standard-series bearings of the same bore, while the deep raceway grooves still carry dependable radial and bidirectional axial loads, rated at 7.28 kN dynamic load.
Sealed on both sides with contact rubber lip seals, the 16004 retains its grease charge for life and keeps out dust, moisture and process debris — a practical choice for maintenance-free operation.
Key Features
- Narrow-section design minimises axial space and weight in compact assemblies
- Deep uninterrupted raceway grooves carry radial and axial loads in both directions
- Low mass and low friction allow very high rotational speeds with minimal torque
- Contact rubber lip seals on both sides retain grease and keep out dust and moisture, giving long maintenance-free life
- Precision-ground raceways and graded balls deliver quiet, smooth running
- ISO 15 / DIN 625 dimension series with CN radial internal clearance (standard)
Typical Applications
Typical applications include robotics and servo axes, medical and laboratory equipment, instruments and encoders, small electric motors and generators, pumps and blowers, printing and textile machinery, and gearboxes where a slim cross-section, low inertia and quiet operation are required.
