Enduro 6805 ABEC-3 Bearing 25x37x7
The Enduro 6805 ABEC-3 is a precision radial cartridge bearing commonly used in bicycle bottom brackets and suspension pivot systems. With its 25 × 37 × 7 mm dimensions, it is a standard size found in many modern MTB and road bike assemblies where smooth rotation and durability are required.
Key Specifications
- Bearing size: 25 × 37 × 7 mm
- Part number: 6805
- Precision rating: ABEC-3
- Type: Radial cartridge bearing
What ABEC-3 Means
ABEC-3 indicates a precision tolerance level:
- Suitable for cycling applications (not ultra-high-speed machinery)
- Balanced for durability and smooth performance
- More than adequate for bottom bracket and pivot loads
Typical Applications
- Bottom brackets (especially press-fit and threaded systems)
- Suspension pivots
- Frame linkage points
- Wheel and hub systems (in some configurations)
Performance Characteristics
- Smooth and consistent rotation under load
- Good balance between precision and longevity
- Designed for real-world MTB conditions (mud, water, grit)
- More efficient rolling than heavy-duty MAX bearings, but with slightly lower load capacity
Why It’s Used
The 6805 size is widely adopted because it:
- Fits many modern crank and BB standards
- Offers strong compatibility across MTB systems
- Provides reliable service life in mixed terrain condition
