Frequently Asked Questions — 6006 Bearing
What are the dimensions of the 6006 bearing?
The 6006 bearing measures 30mm bore × 55mm outer diameter × 13mm width, with a fillet radius of 1mm. This conforms to ISO 15:2017.
What is the load rating of the 6006?
The 6006 has a dynamic load rating (C) of 13.3 kN and a static load rating (C₀) of 6.95 kN. These values are used in ISO 281 L10 life calculations.
What speed can the 6006 run at?
With grease lubrication, the 6006 has a reference speed of 13,000 rpm. With oil lubrication, the limit is 17,000 rpm.
Are SKF, NSK, FAG, and Timken 6006 interchangeable?
Yes. All major bearing brands (SKF, FAG, NSK, NTN, KOYO, NACHI, Timken) produce the 6006 to ISO 15:2017 dimensional standards. They are fully interchangeable on bore, OD, and width dimensions.
What Chinese brands make a 6006 equivalent?
ZWZ, LYC (Luoyang), C&U (Changzhou), and HRB (Harbin) all manufacture 6006 equivalents to ISO 15:2017. Old Chinese GB numbers: 1000906, 60906. All are dimensionally interchangeable with SKF/NSK.
What is the difference between 6006 open, 6006 2RS, and 6006 ZZ?
Open: no seals, suitable for clean environments with re-lubrication access. 2RS (rubber sealed both sides): maintenance-free, best for dusty or wet environments. ZZ (metal shielded): lower torque than 2RS, good dust protection but not waterproof. For most applications, 2RS is recommended.
What shaft tolerance fits the 6006 bearing?
For a rotating inner ring (most common), use shaft tolerance k6 for normal loads or m6 for heavy loads. For a non-rotating shaft, h6 or js6 is appropriate. Housing bore should be H7 for a stationary outer ring. Use our Bearing Fit Calculator for exact tolerance values.
How do I calculate 6006 bearing life?
L10 = (C/P)³ where C = 13.3 kN (dynamic rating) and P is your applied equivalent load (kN). L10h = L10 × 10⁶ / (60 × n), where n is speed in RPM. Use our Bearing Life Calculator to compute this automatically.
