SKF deep groove ball bearings are essential components for supporting radial and axial loads in a wide variety of industrial applications. Their versatile design and ability to operate at high speeds make them a reliable choice for rotating machinery. At MR Accesorios Industriales we carry the SKF brand, with quality and technical support for your projects.
The designation of these bearings follows a coded system that reveals key characteristics. For example, in 6006-2RZTN9/HC5C3WT, the prefix 6006 indicates the size and series (60 for extra-light section, 62 for medium section, 63 for heavy section). The suffix 2RZ indicates low-friction seals on both sides, TN9 a polyamide cage, HC5 ceramic balls, C3 an internal radial clearance greater than normal, and WT a heat treatment for elevated temperatures. This nomenclature allows you to quickly identify the bearing's capabilities.
These bearings are used in electric motors, pumps, fans, compressors, machine tools and transmission equipment. In Argentina, they are common in the automotive, food, textile and agricultural industries. Their ability to withstand high speeds and their low maintenance make them ideal for demanding environments. The combination of seals and polyamide cage reduces noise and vibration, extending equipment service life.
When selecting a bearing, consider the load, speed and environmental conditions. The 2RZ seal protects against contaminants and retains lubricant, ideal for dusty or humid environments. The C3 clearance is suitable when there are thermal differences between the inner and outer rings. The HC5 ceramic balls offer greater wear resistance and lower friction losses. During mounting, ensure correct alignment and avoid impacts that could damage the rings or balls. Proper lubrication and correct fitting are key to optimal performance.
Regarding equivalences, SKF bearings can be interchanged with those of other brands that follow similar designations, such as FAG, NSK or NTN, provided dimensions and specifications match. However, it is essential to verify tolerances and radial clearance, as they may vary between manufacturers. For safe interchangeability, consult equivalence tables or contact our technical team.
