Selection Notes
- F3-8M is a single-direction thrust bearing — supports axial load in one direction only. Never apply radial loads.
- Separable design: shaft washer, housing washer, and ball/cage assembly must be assembled in correct orientation.
- Default material direction is GCr15 bearing steel. Stainless steel direction can be discussed by product scope.
- Use within suitable thrust-bearing operating conditions and provide application details before ordering.
- If both radial and axial loads are present, consider angular contact ball bearings instead.
Before Ordering
F3-8M is extremely small (3mm bore). When ordering, please provide mounting space, shaft washer and housing washer fit, axial-use conditions, and whether a stainless steel direction is needed.
FAQ
"F" series designates thrust ball bearings. "M" typically indicates a caged design (with retainer). F3-8M is a three-piece separable miniature thrust bearing.
Stainless steel direction can be discussed when inquiring. Please provide material requirements and application conditions.
