Bearing 6205

The 6205 bearing is a single-row ball bearing measuring 25 × 52 × 15 mm (inner diameter 25 mm, outer diameter 52 mm, width 15 mm). We stock 27 variants, 16 of which are in stock and ready for dispatch within 24 hours. Prices start at 43 Kč and vary depending on the manufacturer and variant.

Dimensions and interchangeability

The designation 6205 is an international standard (ISO 15), so a 6205 bearing from any manufacturer will always have the same dimensions of 25 × 52 × 15 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 used in the original machine.

Variants we stock

• 6205 2RS – double-sided rubber seals – for dusty and damp environments
• 6205 2RSH – double-sided rubber seal (SKF designation)
• 6205 LLU – double-sided rubber seal (NTN designation)
• 6205 2Z – double-sided metal shield – lower friction, higher speeds
• 6205 ZZ – double-sided sheet metal cover (NTN designation)
• 6205 C3 – increased radial clearance – for higher temperatures and interference fits
• 6205 N – groove for retaining ring on outer ring
• 6205 NR – groove including supplied retaining ring
• 6205 P5 – increased running accuracy (P5 class)

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

Manufacturers

For the 6205 designation, we offer SKF, FAG, NTN, NSK, SNR, ZVL and KG brands. ZVL or KG 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 6205 bearings, so the choice depends on the operating environment: 2RS sealed bearings for dusty and damp conditions; 2Z open bearings for clean and high-speed applications; and C3 clearance bearings for heating or press-fitting.
