Quick guide for bearing selection
A short checklist to evaluate load, speed, and service conditions.
This guide is for first-pass evaluation. For critical applications, always confirm with manufacturer catalogs.
Problem / Objective
In bearing selection, the goal is to identify a bearing type that balances load and speed requirements.
Assumptions
- Load distribution is assumed to be balanced.
- Lubrication and temperature conditions are within typical production ranges.
- Assembly tolerances are inside catalog limits.
Step by step method
Fast selection flow
Common mistakes
Skipping service factors in quick selection can dramatically reduce bearing life.
- Mixing radial and axial loads.
- Ignoring weak lubrication conditions.
- Assuming service factor equals 1.
