The SKF Z/WT series deep groove ball bearing is a single row bearing with metal shield plates on both sides and lubrication for continuous service. It is designed to withstand moderate radial and axial loads in both directions, with low friction and high permissible speed. It is used in electric motors, pumps, fans and transmission equipment where protection against dust and moisture is required without the need for additional seals. MR Accesorios Industriales sells this series as part of its SKF bearing line.
The Z/WT series designation is read as follows: the main number indicates the bearing size, and the bore diameter is deduced from the code according to the standard. The suffix Z indicates that the bearing has a metal shield plate on one side, while /WT indicates a special lifetime lubrication, generally high-temperature grease. 2Z means shield plates on both sides. This nomenclature allows the sealing and lubrication characteristics to be quickly identified.
This type of bearing is used in applications where there is exposure to dust, chips or moderate moisture. In Argentine industry, it is commonly found in low and medium power electric motors, centrifugal pumps, fans, compressors, conveyor belts and machine tools. It is also used in agricultural equipment and in the food industry, where frequent cleaning requires protections that prevent the entry of contaminants without requiring additional maintenance.
To correctly select a Z/WT bearing, take into account the radial and axial load it must withstand, the rotation speed and the environmental conditions. The Z shields protect against solid particles, but they are not liquid-tight; if there is direct contact with water or oil, it is advisable to evaluate an RS or 2RS seal. The /WT lubrication is for life, so it does not require regreasing. During assembly, ensure correct alignment between shaft and housing, and avoid striking the rings so as not to damage the raceways.
Regarding equivalences, SKF Z/WT series bearings can be interchanged with those of other brands that follow the same international designation. For example, a bearing of this SKF series is equivalent to a bearing with the same designation from other brands, as long as the tolerances and lubrication are respected. It is important to verify the /WT suffix to ensure the same grease specification. MR Accesorios Industriales can advise you on interchangeability according to the exact part number.

Frequently Asked Questions
- What are the dimensions of the SKF 608-2Z/WT bearing?
- The SKF 608-2Z/WT bearing has a 8 mm bore, a 22 mm outside diameter and a 7 mm width (8 x 22 x 7 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 608.
- What does the Z/WT suffix mean on an SKF bearing?
- The Z indicates that the bearing has a metal shield plate on one side, which prevents the entry of dust and particles. The /WT suffix indicates a special lifetime lubrication, generally with high-temperature grease. If the code includes 2Z, it means it has shields on both sides.
- Does this bearing need maintenance or regreasing?
- No, the /WT lubrication is for life, so it does not require periodic regreasing. However, it is important to verify that the working conditions do not exceed the maximum temperature allowed by the grease. If in doubt, 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 verify that the lubrication is equivalent. MR Accesorios Industriales advises you on interchangeability according to the exact part number.
