Description
Overview:
The 6004 2RSC3 Deep Groove Ball Bearing is a genuine NTN component for reliable rotation in construction and garden machinery. Made from hardened bearing steel with precision-ground raceways, it reduces friction while supporting mainly radial loads with additional axial capability. The "closed face" design uses rubber contact seals on both sides (2RS) to block dust and moisture, helping to protect the grease and extend service life. C3 internal clearance provides extra room for thermal expansion at sustained speeds, helping the bearing run cooler and smoother in tough conditions. With a 20mm inner diameter, 42mm outer diameter, and 12mm width, this standard 6004-size bearing fits many housings and shafts found in equipment such as lawn mowers, pumps, compact gearboxes and small electric motors. Genuine NTN part for consistent quality and fit.
Key Features:
- Genuine NTN quality for dependable performance and dimensional accuracy
- Standard 6004 size: 20mm ID x 42mm OD x 12mm wide for straightforward replacement
- Closed face with two rubber contact seals (2RS) to keep out dirt, water and debris
- C3 internal clearance for stable running at higher speeds and temperatures
- Deep groove design supports radial loads and moderate axial loads in both directions
- Supplied pre-lubricated with grease for quick installation and low maintenance
- Smooth, low-friction operation thanks to precision-ground raceways and balls
- Durable bearing steel construction for wear resistance and long service life
- Easy to fit in common housings; compatible with standard 20mm shafts
- Suitable for use across construction and horticultural equipment in demanding environments
Typical Applications:
Commonly used in mower deck spindles, idlers and tensioners, compactors, small pumps, electric motors, conveyor rollers and light-duty wheel hubs. Suitable for many rotating assemblies where a compact, sealed 20mm bore bearing is required to keep contaminants out and retain grease for extended service intervals.
Also known as:
Radial ball bearing, single-row ball bearing, 6004-2RS, 6004 C3, 6004 sealed bearing, 6004 deep groove bearing. These terms are often used in service manuals and parts lists for machinery requiring a sealed 20mm bore deep groove bearing with increased internal clearance.
