Decoding SKF 626-2Z/WT
- 62Series
- Deep groove ball bearings, 62 series. Series differ in outside diameter and width even when the bore is the same.
- 6Bore
- Bore: 6 mm.
- 2Z/WTSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
626 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

The SKF Z/WT series deep groove ball bearing is a single row bearing with metal shields on both sides and lifetime lubrication. It handles moderate radial and axial loads in both directions, runs with low friction, and permits high speeds. Typical uses include electric motors, pumps, fans, and transmission equipment where dust and moisture protection is needed without extra seals. MR Industrial Accessories supplies this series as part of its SKF bearing range.
The Z/WT code breaks down as follows: the base number gives the bearing size, and the bore diameter is derived from that number according to the standard. The suffix Z means a metal shield on one side; /WT denotes a special lifetime grease, usually a high-temperature type. When 2Z appears, shields are on both sides. This naming lets you quickly identify sealing and lubrication.
These bearings suit environments with dust, chips, or moderate moisture. In industrial settings, they are common in low- and medium-power electric motors, centrifugal pumps, fans, compressors, conveyor belts, and machine tools. They also appear in agricultural equipment and in food processing, where frequent washdowns demand protection against contaminants without added maintenance.
When selecting a Z/WT bearing, consider the radial and axial loads, the operating speed, and the ambient conditions. The Z shields block solid particles but are not liquid-tight; if water or oil contacts the bearing directly, evaluate an RS or 2RS seal instead. The /WT grease is designed for life, so no regreasing is required. During installation, align shaft and housing correctly and avoid hitting the rings, which could damage the raceways.
For interchangeability, SKF Z/WT series bearings can be replaced by other brands that use the same international designation, provided tolerances and lubrication match. Always confirm the /WT suffix to ensure the grease specification is equivalent. MR Industrial Accessories can advise on interchangeability based on the exact part number.

Frequently asked questions
- SKF 626-2Z/WT bearing: what are its dimensions?
- SKF 626-2Z/WT measures 6 mm across the bore and 19 mm across the outside diameter; its width is 6 mm (6 x 19 x 6 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 626.
- What does the Z/WT suffix mean on an SKF bearing?
- The Z indicates a metal shield on one side, which keeps out dust and particles. The /WT suffix means a special lifetime lubrication, typically with high-temperature grease. If the code includes 2Z, the bearing has shields on both sides.
- Does this bearing need maintenance or regreasing?
- No, the /WT lubrication is for life, so periodic regreasing is not required. However, verify that operating conditions do not exceed the maximum temperature allowed by the grease. If unsure, consult our technical team.
- Can I replace an SKF Z/WT bearing with one from another brand?
- Yes, as long as the designation and tolerances match. For example, a bearing of this series can be replaced by one from another brand with the same designation, but check that the lubrication is equivalent. MR Industrial Accessories advises on interchangeability according to the exact part number.
