Product Description
F3-8M Miniature Thrust Ball Bearing Customizable For Medical / Precision Instruments
The F3-8M Miniature Thrust Ball Bearing is a compact, high-performance solution engineered for applications where space is limited but performance cannot be compromised. This precision component ensures smooth and efficient operation across diverse industries.
Compact and Precise Dimensions
| Parameter | Value |
|---|---|
| Inner Diameter (d) | 3.000 mm |
| Outer Diameter (D) | 8.000 mm |
| Height (H) | 3.500 mm |
| Bore Dia. Clearance (d1) | 3.200 mm |
| Outer Dia. Pilot (D1) | 7.800 mm |
| Radius (min) (rs) | 0.15 mm |
The 3.000 mm inner diameter provides a precise fit for small shafts, minimizing play and misalignment while optimizing energy consumption. The 8.000 mm outer diameter balances load-carrying capacity with space constraints, while the 3.500 mm height ensures optimal internal volume for smooth component movement.
Structural Configuration
The F3-8M features two washers (shaft and housing) with high-quality steel ball rolling elements and a bronze or stainless steel cage. The cage:
- Guides rolling elements along intended paths
- Prevents ball collisions and reduces wear
- Extends bearing service life
- Prevents ball dislodgement under high-speed or high-load conditions
The separable design allows individual component installation and removal, simplifying maintenance and reducing repair costs.
Material Specifications
Crafted from premium 52100 chrome steel for washers and balls, offering:
- High hardness for substantial axial load capacity
- Excellent strength for high-speed rotation and heavy-duty applications
- Superior wear resistance for extended service life
Cage materials (bronze or stainless steel) provide additional durability, wear resistance, and corrosion protection for various operating environments.
Performance Characteristics
Robust Axial Load Capacity
Handles significant unidirectional axial forces, ensuring axial stability in precision machinery and maintaining output quality through reliable load transmission.
Smooth and Quiet Operation
Precise manufacturing and optimized design minimize vibration and noise, making it ideal for medical equipment and high-precision optical instruments where stability is critical.
High-Speed Compatibility
Operates at up to 19,000 rpm (grease lubricated) or 28,000 rpm (oil lubricated), suitable for high-speed applications including power tools and dental drills.
Application Areas
Automotive and Transportation
Used in transmission systems of miniature electric vehicles, throttle control mechanisms, wheel assemblies, and vibration-damping systems.
Instrumentation and Precision Machinery
Applied in precision measuring instruments, electronic weighing scales, optical instruments (microscopes, telescopes), and miniature lathes/milling machines.
Medical and Healthcare
Utilized in handheld surgical tools, medical diagnostic equipment, blood analyzers, and imaging devices where reliability and precision are paramount.
Hobby and DIY Projects
Popular in RC vehicles (motor, gearbox, steering systems) and DIY-built small-scale machines or robots for enhanced performance and durability.
The F3-8M bearing delivers reliable performance through its compact dimensions, optimized structure, premium materials, and outstanding performance characteristics, making it an essential component across diverse mechanical systems.
