Bearing 6006

The 6006 bearing is a single-row ball bearing measuring 30 × 55 × 13 mm (internal diameter 30 mm, external diameter 55 mm, width 13 mm). We stock 16 variants, 10 of which are in stock with dispatch within 24 hours. Prices start at 36 Kč and vary depending on the manufacturer and variant.

Dimensions and interchangeability

The designation 6006 is an international standard (ISO 15), so a 6006 bearing from any manufacturer always has the same dimensions of 30 × 55 × 13 mm and is mechanically interchangeable. They differ only in terms of seal design, clearance, precision and service life. When replacing a worn part, you can therefore choose a different brand to the one originally fitted in the machine.

Variants we stock

• 6006 2RS – double-sided rubber seals – for dusty and damp environments
• 6006 2RS1 – double-sided rubber seal (SKF designation)
• 6006 LLU – double-sided rubber seal (NTN designation)
• 6006 2Z – double-sided metal cover – lower friction, higher speeds
• 6006 ZZ – double-sided sheet metal cover (NTN designation)
• 6006 C3 – increased radial clearance – for higher temperatures and interference fits

Without a suffix, this is an open bearing without seals — the most economical option for clean and permanently lubricated mountings.

Manufacturers

For the 6006 designation, we offer SKF, FAG, NTN, ZVL, IBB and KG brands. ZVL or IBB are sufficient for standard operation; for demanding and high-speed applications, we recommend SKF, FAG or NTN.

How to choose

The dimensions are identical for all 6006 bearings, so the choice depends on the environment: 2RS sealed bearings for dusty and damp conditions; 2Z covered bearings for clean and high-speed applications; and C3 clearance for heating or press-fitting.
