The SKF 2RSH/C3HT series deep groove ball bearing is a component designed to withstand radial and axial loads in applications where the operating temperature is high. Its sealed construction and C3 internal clearance make it suitable for demanding environments, such as ovens, industrial fans and continuous process equipment. MR Accesorios Industriales carries this line as part of its SKF bearing offering.
The designation of this series combines several suffixes that indicate specific characteristics. 2RSH indicates that the bearing has two synthetic rubber contact seals, one on each side, which retain the lubricant and block the entry of contaminants. C3 indicates an internal radial clearance greater than normal, necessary to compensate for thermal expansion. HT specifies that the lubricant and seals are prepared for high temperatures. Thus, a code such as 6004-2RSH/C3HT reads: deep groove ball bearing, 60 series, bore diameter 20 mm, with seals, C3 clearance and suitable for high temperature.
These bearings are used in applications where heat is a critical factor. In Argentina, they are commonly found in induced draft fans, industrial ovens, dryers, boilers and process equipment in chemical, food and ceramic plants. They are also used in electric motors in hot areas, thermal fluid pumps and conveyors operating near heat sources. Their ability to withstand high temperatures without losing lubrication makes them ideal for maintenance in industries that cannot stop production.
To correctly select a bearing from this series, it is essential to verify the actual operating temperature and the type of load. C3 clearance is essential when there are significant thermal gradients, since it prevents the bearing from becoming preloaded and failing prematurely. During mounting, adequate alignment between shaft and housing must be ensured, and adjustment methods that do not damage the seals must be used. Lubrication is defined at the factory; mixing with other greases is not recommended. If the environment is very dirty, evaluate additional protections.
As for equivalents, deep groove ball bearings with seals and increased clearance for high temperature are available from different brands under similar, though not identical, nomenclatures. For example, other manufacturers may use suffixes such as 2RS, C3 and HT separately or combined. It is always advisable to verify the critical dimensions and service conditions before replacing one brand with another. MR Accesorios Industriales can advise you on interchangeability according to the exact code and your equipment's needs.

Frequently Asked Questions
- What are the dimensions of the SKF 6004-2RSH/C3HT bearing?
- The SKF 6004-2RSH/C3HT 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 HT suffix mean on an SKF bearing?
- HT indicates that the bearing is prepared for high temperatures. This means that both the lubricant and the seals and the heat treatment of the steel are suitable for operating in temperature ranges above conventional ones, without losing performance.
- When is it advisable to use a bearing with C3 clearance?
- C3 clearance is recommended when the bearing will work with temperature differences between the shaft and the housing, since it compensates for thermal expansion. Also in applications where a looser fit is required to avoid excessive preload.
- Can an SKF 2RSH/C3HT bearing be replaced by another brand?
- Yes, as long as the dimensions and service conditions are verified. Other brands may offer bearings with equivalent characteristics, but it is important to confirm that the internal clearance, the type of sealing and the permissible temperature are compatible.
