Description
Overview:
The Ball Bearing 6301DDUCMPS2S is a genuine Hikoki spare for selected disc grinders and other heavy-duty power tools. It is a sealed deep groove ball bearing made from high-grade bearing steel with rubber seals on both sides (DDU) to keep dust and grit out. This helps maintain smooth rotation, reduces friction and wear, and supports reliable, long service life in abrasive environments. As an OEM-equivalent to 6301DD, it is a direct replacement for worn or noisy bearings in Hikoki grinders such as the G18MR and G18SE3. Typical 6301 dimensions are 12 mm (bore) x 37 mm (outside diameter) x 12 mm (width), making it a common fit in motor and gearbox locations. Supplied pre-greased and ready to install.
Key Features:
- Genuine Hikoki part for assured fit and performance in specified models
- DDU rubber seals on both sides for improved dust and moisture protection
- Pre-greased, low-maintenance design for quick, clean replacement
- Standard 6301 size (12 x 37 x 12 mm) for common armature/gearbox positions
- Durable bearing steel construction for long life under high loads and speeds
- Helps restore smooth running, reduce noise, and limit vibration
- Suitable for demanding jobsite conditions found in grinding and cutting tasks
- Direct replacement for OEM reference 6301DD and listed alternates
Typical Applications:
Used in motor and gearbox assemblies of Hikoki angle grinders and related tools where a 6301 sealed bearing is specified. Ideal during routine servicing, armature rebuilds, or when fixing excessive play, roughness, or noise. Suitable for construction, metalworking, and site maintenance where abrasive dust is present.
