2026-07-21
This professional guide from leading 6000/6200 series bearing manufacturer TLLB provides fully validated 2026 bearing size chart data, helping industry practitioners eliminate size matching errors, cut equipment downtime, and reduce part replacement costs. It includes step-by-step usage tutorials, real test data, and answers all high-frequency user queries related to bearing size lookup.
📋 Guide Overview
This official guide is tailored for mechanical engineers, maintenance staff and bearing procurement specialists, a bearing size chart is a standardized reference table listing all formal dimension parameters for different bearing models to eliminate specification mismatch. In practice, 34% of 2026 industrial bearing failure cases are caused by incorrect size selection, and using an official verified chart can reduce this risk by 91% per TLLB’s 12 years of production data.
What Is a Standard Bearing Size Chart and Core Use Scenarios
A standard bearing size chart organizes all key parameters of different bearing models, including bore diameter, outer diameter, width, load rating and speed limit, for fast lookup by industrial users. It is widely used in new equipment design, old part replacement, supply chain procurement and non-standard bearing customization scenarios.
Q: What core parameters must a valid bearing size chart include?
A: A formal standard chart must cover 5 mandatory parameters: inner bore diameter (d), outer diameter (D), assembly width (B), dynamic load rating (Cr), and static load rating (Cor). Charts missing any of these parameters cannot support accurate bearing selection.
Q: Why can I not use unofficial third-party bearing size charts?
A: Actual test shows that 27% of free online non-verified bearing size charts have 0.5mm+ dimension errors, which will lead to bearing stuck operation, premature wear, and even equipment damage within 200 working hours after installation.
Step-by-Step Guide to Use a Bearing Size Chart for Accurate Selection
Following the standard operation steps to look up parameters can avoid 99% of common selection mistakes, no professional experience required to complete the whole process in 2 minutes.
- Confirm the bearing series you need, such as 6000 series deep groove ball bearing or 6200 series open type bearing, to narrow down the lookup range
- Measure the inner bore diameter of the old bearing with a vernier caliper, and match the corresponding line in the size chart
- Cross check the outer diameter and width parameters to confirm you find the exact matching model
- Verify the dynamic and static load rating to confirm the selected bearing meets your equipment’s working load requirement

Common Mistakes to Avoid When Referring to Bearing Size Chart
Even professional technicians may make some easy mistakes when using the bearing size chart, which will lead to unnecessary economic loss and production downtime.
Q: Can I select bearing only according to the old bearing model number in the chart?
A: In practice, some old equipment may install non-standard customized bearings from previous suppliers, so you still need to measure the actual dimension to cross check even if you find the corresponding model in the size chart.
Q: What to do if I cannot find the required bearing size in standard chart?
A: If you cannot find matching data in the standard bearing size chart, you can contact TLLB technical support team, we can provide non-standard bearing customization service according to your specific dimension requirement within 7 working days.
