The SKF 619 series deep groove ball bearing is a thin-section, sealed bearing with C3 internal clearance. It is used in applications where radial space is limited and a compact bearing is required, such as in small electric motors, precision instruments, pumps and fans. Its single row ball design supports moderate radial and axial loads in both directions. MR Accesorios Industriales supplies this official brand and advises you to choose the correct code.

The designation of this bearing is read in parts. The number 61904 indicates the 619 series, which is thin-section, and the 20 mm bore. The suffix 2RS1 means it has rubber seals on both sides, which retains the lubricant and blocks the entry of contaminants. The suffix C3 indicates a radial internal clearance greater than normal, useful when there is thermal expansion or interference fits. HGJN is a high-temperature, long-life lubricant code. For example, the code 61904-2RS1/C3HGJN combines all these characteristics.

This type of bearing is found in equipment where space is critical and smooth, quiet operation is needed. It is common in low-power electric motors, fans, small centrifugal pumps, measuring instruments and office machines. In Argentine industry, it is seen in packaging lines, medical equipment, and textile machinery. Its ability to support combined loads and its low noise level make it suitable for precision applications.

To select the correct bearing, take into account the internal clearance: C3 is recommended when the shaft or housing fit generates compression on the rings, or when the working temperature is high. The 2RS1 seal is suitable for environments with moderate dust or moisture, but if there are high speeds, verify that the lubricant and the seal allow it. When mounting, make sure to align the shaft and housing well, and avoid hitting the seals. Factory lubrication is sufficient for most cases, but under severe conditions it may require relubrication.

Regarding equivalences, deep groove ball bearings of similar series from other manufacturers can be interchanged, but always verify the tolerances and the internal clearance. Suffixes may vary between brands: for example, an SKF 2RS1 seal may be equivalent to 2RS from another brand, but do not assume that the lubricant or clearance are identical. It is best to consult a specialist before replacing one bearing with another of a different brand.
