- 5Bore
- Bore: 5 mm.
- 2Z/VT378Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
W 625 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF W 625-2Z/VT378 measures 5 mm across the bore and 16 mm across the outside diameter; its width is 5 mm (5 x 16 x 5 mm).

When moisture, chemicals or frequent washdowns are part of the operating environment, SKF stainless steel deep groove ball bearings are built to handle radial and axial loads in both directions. Their stainless construction limits corrosion, which makes them a practical choice for food processing, pharmaceutical equipment and machinery that works outdoors. The line covers many sizes and sealing options, so it can suit a broad range of speeds and duty conditions.
Reading the part number helps you order correctly. The leading W tells you the rings and rolling elements are stainless steel. Next comes the series, such as 60, 62, 63 or 619, which sets the boundary dimensions. Then the sealing suffix appears: 2Z means two shield plates, while 2RS means two elastomer seals. A slash followed by VT and a number, as in W 625-2Z/VT378, identifies the grease or special lubricant. So W 6000-2Z/VT127 is a light-series bearing with metal shields and a specific grease fill.
These bearings show up wherever corrosion is a constant concern. Food and beverage plants that wash equipment every day rely on them, as do pharmaceutical packaging and filling machines. You will also find them in laboratory instruments, pumps, fans and conveyors running in damp areas, and in marine or coastal installations. Because they tolerate washdowns without rusting, they fit sanitary processing zones well.
Selection comes down to sealing and lubrication. Choose 2Z for protection against dust and dirt; it does not hold liquids back. Choose 2RS when splashes are present, since the elastomer seals are tighter. The VT suffix points to a grease formulated for stainless steel and the expected operating conditions. At mounting, line up shaft and housing correctly to avoid extra loads, use the right tools and do not strike the rings, so the seals and cage stay intact.
For interchange, SKF stainless bearings can be replaced by other brands that share the same standardized dimensions. The W prefix is SKF's own way of marking stainless steel; other makers use different codes. Before substituting, confirm bore, outside diameter, width and sealing type. Lubricant suffixes also differ between manufacturers, so check the technical data. MR Industrial Accessories can help you verify interchangeability.

Frequently asked questions
- SKF W 625-2Z/VT378 bearing: what are its dimensions?
- SKF W 625-2Z/VT378 measures 5 mm across the bore and 16 mm across the outside diameter; its width is 5 mm (5 x 16 x 5 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation W 625.
- What does the VT suffix mean in the designation?
- VT followed by a number identifies the grease or special lubricant the bearing is pre-lubricated with. Each VT code is a specific formulation suited to certain temperature conditions and compatible with stainless steel.
- What is the difference between 2Z and 2RS?
- 2Z means two metal shield plates, which keep out dust and dirt but do not retain liquids. 2RS means two elastomer seals, which give tighter sealing against splashes and humid environments.
- Can I replace an SKF bearing with another brand?
- Yes, provided the bore, outside diameter, width and sealing type match. The W designation is specific to SKF, but other manufacturers offer stainless steel equivalents. Always verify the technical specifications.
