How to read NSK part numbers

NSK writes its part numbers without spaces or hyphens: the basic number, then the seal code, then the clearance. A sealed 6204 with NSK’s motor clearance is written 6204DDUCM, and a shielded C3 6205 6205ZZC3. NSK also uses its own seal codes, DDU and VV, rather than the 2RS seen on other brands.

The NSK codes you will see most often:

CM or C3? Both are clearances used in electric motors. CM is NSK’s own motor clearance range, chosen for quiet running. If the old bearing says CM, replace it with CM where possible, or ask us before substituting C3.

Same bearing, other brands

Every maker writes the same bearing differently. Here is a sealed 6205 with C3 clearance (25 × 52 × 15 mm) in each brand’s own style, so you can match a NSK part number to its equivalent in another brand, or the other way round. Always check the full suffix before swapping brands.

How to spot a fake NSK bearing

NSK motor bearings are popular, and therefore copied. Because NSK uses distinctive codes, the part number itself is often the quickest giveaway:

• Check the seal code. NSK uses DDU (contact seals) and VV (non-contact seals). A box marked NSK 6205-2RS uses another maker’s suffix and should be questioned.
• Check the number’s style. Genuine NSK numbers run together without hyphens or spaces, such as 6204DDUCM. Odd spacing or punctuation is a warning sign.
• Match the bearing to the label. The designation on the ring should match the box exactly.
• Look at the markings and seals. Genuine markings are sharp and even, and seals sit flush and evenly all round.
• Question the price, and if in doubt, ask. Prices far below the market rate are a warning sign. If you have doubts about bearings you already hold, bring them in and we will give you an honest opinion.
