Bearing 6208

The 6208 bearing is a single-row ball bearing measuring 40 × 80 × 18 mm (inner diameter 40 mm, outer diameter 80 mm, width 18 mm). We stock 18 variants, 13 of which are in stock with dispatch within 24 hours. Prices start at 85 Kč and vary depending on the manufacturer and variant.

Dimensions and interchangeability

The designation 6208 is an international standard (ISO 15), so a 6208 bearing from any manufacturer will always have the same dimensions of 40 × 80 × 18 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 from the one used in the original machine.

Variants we stock

• 6208 2RS – double-sided rubber seals – for dusty and damp environments
• 6208 2RS1 – double-sided rubber seal (SKF designation)
• 6208 LLU – double-sided rubber seal (NTN designation)
• 6208 2Z – double-sided metal shield – lower friction, higher speeds
• 6208 ZZ – double-sided sheet metal cover (NTN designation)
• 6208 C3 – increased radial clearance – for higher temperatures and interference fits
• 6208 N – groove for retaining ring on the outer ring

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

Manufacturers

For the 6208 designation, we offer SKF, NTN, INA, SNR, ZVL, IBB and KG brands. ZVL or IBB are sufficient for standard operation; for demanding and high-speed applications, we recommend SKF, NTN or INA.

How to choose

The dimensions are identical for all 6208 bearings, so the choice depends on the environment: the 2RS with seals for dusty and damp conditions; the 2Z with covers for clean and high-speed applications; and C3 clearance for heating or press-fitting.
