Decoding SKF W 61900-2Z/W64
- W 619Series
- Stainless steel deep groove ball bearings, W 619 series. Series differ in outside diameter and width even when the bore is the same.
- 00Bore
- Bore 10 mm: by standard, 00 designates 10 mm.
- 2Z/W64Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
W 61900 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

The SKF stainless steel deep groove ball bearing is a single row bearing whose rings and balls are made of stainless steel. It is meant for humid, corrosive settings and for equipment that gets washed down often, where a carbon steel bearing would rust. Its rigid design carries moderate radial and axial loads in both directions. MR Industrial Accessories supplies this SKF line, so send your size or part number for a quote.
Reading the designation helps you order the right replacement. The W prefix means the ring and rolling elements are stainless steel. The basic number, such as 61900, sets the series and size. Suffixes describe the variant: -Z is one metal shield, -2Z is two metal shields, and /W64 covers an execution with special lubrication or tolerance characteristics. In W 61900-2Z/W64 and W 61900-Z/W64 you can see stainless material, 61900 series and shield type combined.
These bearings suit plants where corrosion cuts short the life of conventional bearings: food and beverage facilities, industrial washdown zones, chemical processing equipment, pharmaceutical machines and packaging systems. They also fit marine or coastal installations, where humidity and salinity attack carbon steel. Typical equipment includes conveyors, pumps, fans and mixers that are washed daily or handle products giving off corrosive vapors.
Selection starts with the contaminant. A -Z or -2Z shield keeps out dust and splashes, but the bearing should not be immersed in liquids. Lubrication has to match the environment, and water-resistant greases are recommended for wet duty. When mounting, check shaft and housing alignment and avoid striking the rings. Cleaning the seat and using the correct tools helps service life, and frequent washing may call for periodic relubrication.
On interchangeability, SKF stainless steel bearings can be swapped with other brands that share the same dimensional and sealing designation, for instance the 61900, 6000 or 6200 series in stainless version. Tolerances and lubricants are not identical across every manufacturer, so confirm the complete part number and the service conditions before replacing. We can advise on interchangeability without compromising equipment performance.

Frequently asked questions
- SKF W 61900-2Z/W64 bearing: what are its dimensions?
- SKF W 61900-2Z/W64 measures 10 mm across the bore and 22 mm across the outside diameter; its width is 6 mm (10 x 22 x 6 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation W 61900.
- What does the -2Z suffix mean on an SKF bearing?
- It means the bearing has two metal shields, one per side. They protect against dust and splashes, but they are not sealed against immersion, so contact seals should be evaluated for liquid exposure.
- Is this bearing suitable for frequent washdowns?
- Its stainless steel resists corrosion better than carbon steel. However, -Z shields are not sealed, so direct jets or immersion call for contact seals and suitable lubrication.
- Can I replace an SKF stainless steel bearing with one from another brand?
- Yes, if dimensions and sealing type match. Check that the part number is equivalent, such as the same series and suffixes. Tolerances and lubricants may vary, so contact us before installing.
