The SKF RS/MTF series deep groove ball bearing is a single row bearing with double-sided sealing and factory-defined lubrication. It is used in equipment requiring low friction, high speed and protection against contaminants. It is a common choice in electric motors, pumps, fans and machine tools. MR Accesorios Industriales supplies this line as a brand for the Argentine industrial market.
The designation of this series combines the RS suffix and the MTF code. The RS suffix indicates that the bearing has rubber seals on both sides, which retains the lubricant and blocks the entry of dust and moisture. The MTF code identifies a special factory lubrication, usually a high-performance grease for specific temperature or speed conditions. A concrete example is 6018-2RS1/MTF3, where the number 6018 defines the size and the suffixes the sealing and lubricant characteristics.
This type of bearing is found in applications where cleanliness and lubricant retention are critical. In Argentina it is seen in electric motors in the food industry, centrifugal pumps, induced draft fans, conveyor belts and machine tools. Also in mining and cement equipment, where dust is a constant challenge. Its double-sided sealing makes it suitable for environments with fine particles or vapors, provided that speed and temperature limits are respected.
To select correctly, take into account the internal clearance, the type of sealing and the lubrication. The RS seal is contact, so it provides greater protection but also somewhat more friction; if the equipment runs at very high revolutions, evaluate whether a non-contact seal is preferable. The MTF lubrication is factory-defined and must not be mixed with other greases. During mounting, ensure correct alignment between shaft and housing, and avoid impacts that could damage the seals or the raceways.
Regarding equivalences, deep groove ball bearings with double-sided sealing are available from different brands under similar nomenclatures, although the suffixes may vary. For example, other manufacturers use 2RS, 2RSH or DDU to indicate rubber seals. Dimensional interchangeability is usually guaranteed if the bore, outer diameter and width match, but the lubrication and sealing conditions may differ. Always verify the original manufacturer's data sheet before replacing one bearing with another of a different brand.

Frequently Asked Questions
- What are the dimensions of the SKF 6018-2RS1/MTF3 bearing?
- The SKF 6018-2RS1/MTF3 bearing has a 90 mm bore, a 140 mm outside diameter and a 24 mm width (90 x 140 x 24 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6018.
- What does the RS suffix mean on an SKF bearing?
- The RS suffix indicates that the bearing has rubber seals on both sides. These seals retain the lubrication and protect against the entry of contaminants such as dust and moisture. It is a common configuration in applications where greater durability is sought in dirty environments.
- What is the difference between a sealed and a shielded bearing?
- A sealed bearing (RS) uses rubber seals that make contact with the inner ring, offering better sealing but greater friction. A shielded one (ZZ) uses metal shields without contact, with lower friction but less protection. The choice depends on the environment and the speed.
- Can I replace an SKF RS/MTF bearing with one from another brand?
- Yes, provided that the main dimensions (bore, outer diameter and width) match and the sealing and lubrication conditions are compatible. Always verify the replacement's data sheet, because suffixes and lubricants may vary between manufacturers.
