The SKF deep groove ball bearing of the Z series with the 2RST A suffix is a single row bearing designed to withstand moderate radial and axial loads in both directions. Its robust construction and ability to rotate at high speeds make it suitable for a wide variety of industrial applications. At MR Accesorios Industriales we carry this SKF line, an official brand that MR sells, and we advise you so you can choose the right bearing for your equipment.
The designation of this series is interpreted by its letters and suffixes. The initial Z indicates that the bearing incorporates a sheet metal shield on one side, which retains the lubricant and offers protection against coarse particles. The 2RST suffix indicates two contact seals made of synthetic material, which provide sealing against dust and moisture. The final A may refer to an internal design variant. A specific example is Z 9504 2RST A, where the central numbers identify the size. This combination of shield and seals offers high protection, suitable for environments with moderate contamination.
This type of bearing is used in equipment where a balance between speed, load and protection is required. In Argentine industry, it is commonly found in electric motors, centrifugal pumps, fans, conveyors and agricultural machinery. Its ability to withstand loads in both directions makes it versatile for belt or chain drives. It is also used in applications where lubrication must remain confined, such as in food processing equipment or in environments with dust. The Z series with 2RST A seals is a reliable option for continuous service under demanding conditions.
To select correctly, take into account the radial and axial load it will have to withstand, as well as the rotation speed. The combination of shield and contact seals increases resistance to contamination, but can also slightly increase torque and limit maximum speed. Verify that the housing and shaft have the appropriate tolerances and that alignment is correct to avoid parasitic loads. During assembly, apply force on the ring that is fixed, never through the rolling elements. If the bearing comes lubricated from the factory, it is not necessary to add lubricant; if not, follow the manufacturer's recommendations.
Regarding equivalences and interchangeability, deep groove ball bearings with similar suffixes from other manufacturers may be compatible, but it is essential to verify the main dimensions and the type of sealing. Not all suffixes mean the same thing across brands. Therefore, always confirm the full part number and technical specifications before replacing a bearing. At MR Accesorios Industriales we can help you identify the correct equivalence and get the right product for your application.

Frequently Asked Questions
- What does the 2RST suffix mean on this SKF bearing?
- The 2RST suffix indicates that the bearing has two contact seals made of synthetic material, one on each side. These seals retain the lubricant and protect against the ingress of dust and moisture, extending service life in contaminated environments.
- Does this bearing come lubricated from the factory?
- SKF bearings with seals or shields generally come lubricated for life. If yours is not, consult the manufacturer's recommendations to choose the right lubricant. Do not mix different types of lubricants without verifying compatibility.
- How do I know if I can replace a bearing from another brand with this SKF one?
- To replace one bearing with another from a different brand, compare the main dimensions (inner diameter, outer diameter and width) and the type of sealing. Suffixes may vary between manufacturers, so verify the technical specifications. At MR we help you find the equivalence.
