The SKF PER line covers medium-section deep groove ball bearings built to carry radial and axial loads in either direction. Because they come sealed, they hold up well where dust or moderate humidity is present. Electric motors, pumps, fans and transmissions are typical homes for them. MR supplies these bearings and can point you to the right variant for your equipment.
Reading the code is the fastest way to order correctly. The PER prefix is followed by four digits that set the size: PER.6002-ZZDC3V2 sits in the 60 series, the lightest of the three; PER.6210-ZZDC3V2 belongs to the 62 series, a medium section; and PER.6313-ZZDC3V2 falls in the 63 series, which handles more load. After the size come the suffixes. ZZ means sheet metal shields on both sides, C3 means radial internal clearance above normal, and V2 refers to a defined dimensional tolerance. Match all of them and the replacement drops in without surprises.
You will run into these bearings across a broad range of plant equipment: low and medium power electric motors, centrifugal pumps, fans, compressors, conveyor belts and machine tools. Food processing lines also use them, since the shielding keeps residues out, as do textile and plastics operations. That range is what makes them a common pick when a maintenance job calls for a replacement.
Selection comes down to radial and axial load, operating speed and the surrounding conditions. ZZ shielding blocks dust and splashes, though it is not meant for submersion. Choose C3 clearance where thermal expansion is expected, such as high speeds or a temperature gap between the inner and outer rings. Set the bearing correctly during mounting and avoid impacts that could mark the raceways. In ordinary service, the grease applied at the factory typically lasts the life of the bearing.
Deep groove ball bearings follow international standards, so dimensions interchange across manufacturers. Suffixes are another matter: a shield one maker calls ZZ may appear as 2Z or 2RS elsewhere. Confirm the full part number and tolerances before you swap anything. Send us the original reference and we will help you locate the equivalent.

Frequently asked questions
- What does the ZZ suffix mean on these bearings?
- It means the bearing carries sheet metal seals on both sides. They keep out dust and splashes but are not hermetic, so a rubber-sealed variant is the better choice around liquids.
- When should I pick a bearing with C3 clearance?
- C3 suits applications running at high speed or with a temperature difference between the inner and outer rings. The extra clearance absorbs thermal expansion and keeps preload from building up.
- Can an SKF bearing be replaced by another brand?
- Yes. Deep groove ball bearings are made to international dimensional standards, so other brands can interchange. Check the suffixes and tolerances first, since these differ from one manufacturer to the next.
