Bearing 6210

The 6210 bearing is a single-row ball bearing measuring 50 × 90 × 20 mm (internal diameter 50 mm, external diameter 90 mm, width 20 mm). We stock 21 variants, 8 of which are in stock for dispatch within 24 hours. Prices start at 139 Kč and vary depending on the manufacturer and variant.

Dimensions and interchangeability

The designation 6210 is an international standard (ISO 15), so a 6210 bearing from any manufacturer always has the same dimensions of 50 × 90 × 20 mm and is mechanically interchangeable. They differ only in terms of seal type, 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

• 6210 2RS – double-sided rubber seals – for dusty and damp environments
• 6210 2RS1 – double-sided rubber seal (SKF designation)
• 6210 LLU – double-sided rubber seal (NTN designation)
• 6210 2Z – double-sided metal shield – lower friction, higher speeds
• 6210 ZZ – double-sided sheet metal cover (NTN designation)
• 6210 C3 – increased radial clearance – for higher temperatures and interference fits
• 6210 N – groove for a 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 6210 designation, we offer SKF, FAG, NTN, ZVL and IBB 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 the same for all 6210 bearings, so the environment is the deciding factor: 2RS sealed bearings for dusty and damp conditions, 2Z open bearings for clean and high-speed applications, and C3 clearance for heating or press-fitting.
