The SKF 6004 is a single-row deep groove ball bearing engineered for versatile industrial and mechanical applications globally. Known for low friction, smooth performance, and robust reliability, it is often searched by engineers and procurement specialists looking for “SKF 6004 bearing”, “6004 deep groove”, or “20x42x12 SKF”.
Low friction, efficient operation: Deep groove geometry gives smooth rotation and energy efficiency.
Versatile mounting: Suitable for radial loads and moderate axial loads.
Wide variant selection: Open, shielded (ZZ) or sealed (2RS) versions allow adaptation to different environments.
High durability: Excellent fatigue strength and stability under load.
Global reliability: SKF brand ensures consistent quality, tolerances, and compatibility.
Reduced maintenance: Sealed versions (2RS) help keep contaminants out and retain lubricant.

Apply force only to the appropriate bearing ring (inner or outer) — avoid pressing through shields or seals.
Use correct mounting tools to protect the bearing.
If using sealed (2RS) bearings, lubrication is factory-filled; avoid re-lubrication unless specified.
Monitor bearing temperature and vibration during initial run-in.
In dusty or wet environments, prefer sealed or shielded variants (e.g., 6004 2RS).
For high-temperature or chemical environments, review seal and material compatibility.
Q: What does “6004” mean in the bearing’s name?
A: “6004” is the series and dimensional code: bore 20 mm, outer diameter 42 mm, width 12 mm in the 6000 series of deep groove bearings.
Q: Are sealed versions available?
A: Yes — common variants include 6004 2RS (double rubber seals) and 6004 ZZ (metal shields).
Q: What is the maximum speed of SKF 6004?
A: In sealed configuration, typical limiting speed is around 11,000 rpm, depending on lubrication and operating conditions.
Q: Can this bearing carry axial loads?
A: Yes, but only moderate axial loads; its primary design is for radial loading.
Q: Is stock available and how fast is delivery?
