SKF RZ/LHT series deep groove ball bearings are components designed to withstand moderate radial and axial loads in applications requiring effective sealing and long-life lubrication. Their sealed construction with special grease makes them ideal for environments with dust, moisture or variable temperatures. At MR Accesorios Industriales we offer them for industrial equipment that needs reliability and low maintenance.
The designation of these bearings combines the basic series number with suffixes indicating specific characteristics. For example, in 6001-2RZ/LHT23, 2RZ indicates that the bearing has two low-friction seals, one on each side, which protect against contamination without generating the heat of a contact seal. The suffix LHT23 identifies a high-temperature, long-life grease, suitable for demanding conditions. Other examples such as 6004-2RZ/LHT23 and 6005-2RZ/LHT23 follow the same logic: the initial number defines the size, and the suffixes define sealing and lubrication.
These bearings are used in a wide variety of industries in Argentina, such as food, textile, metallurgical and agricultural. They are common in electric motors, fans, pumps, conveyors and process machinery. Their RZ sealing makes them suitable for environments with dust or moderate moisture, where the goal is to reduce maintenance and prevent lubricant loss. In plants where cleanliness is critical, such as in the food industry, they provide an effective barrier without requiring external lubrication systems.
To select the right bearing, take into account the radial and axial load it must withstand, the rotational speed and the environmental conditions. The 2RZ seal is non-contacting, which reduces torque and allows higher speeds, but it is not as tight as a contact seal; evaluate whether the environment requires greater protection. LHT23 grease is formulated for high temperatures and long life, but verify that it is compatible with the thermal range of your application. During mounting, ensure correct alignment and avoid impacts that could damage the seals or raceways.
Regarding equivalents and interchangeability, deep groove ball bearings with 2RZ sealing and special lubrication can be found from other brands with similar designations, although the suffixes may vary. Always verify the critical dimensions and operating conditions before replacing one bearing with another from a different manufacturer. MR Accesorios Industriales offers leading brands and can advise you on the best option for your equipment, ensuring compatibility and performance.

Frequently Asked Questions
- What are the dimensions of the SKF 6004-2RZ/LHT23 bearing?
- The SKF 6004-2RZ/LHT23 bearing has a 20 mm bore, a 42 mm outside diameter and a 12 mm width (20 x 42 x 12 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6004.
- What does the 2RZ suffix mean on these bearings?
- The 2RZ suffix indicates that the bearing has two low-friction seals, one on each side. These seals protect against the entry of contaminants and retain grease, but because they are non-contacting they allow higher speeds and lower heat generation.
- What applications is LHT23 grease suitable for?
- LHT23 grease is designed for high temperatures and long life. It is suitable for applications where the bearing operates continuously at elevated temperatures, such as electric motors, industrial fans or process equipment that does not receive frequent maintenance.
- Can I replace an SKF bearing with one from a different brand?
- Yes, as long as the main dimensions and load and speed conditions are compatible. We recommend verifying tolerances and the type of sealing. At MR Accesorios Industriales we can advise you to choose the best alternative for your equipment.
