The SKF deep groove ball bearing is an essential component for supporting radial and axial loads in industrial machinery. Its single-row ball design with deep raceways allows high speeds and long service life. At MR Accesorios Industriales we supply this brand for applications demanding precision and reliability.
The designation of these SKF bearings includes suffixes that indicate special features. For example, in 6212 TN2/HC5C5S0, the prefix 6212 corresponds to the type and size, while TN2 indicates a glass fiber reinforced polyamide cage. The suffix HC5 indicates silicon nitride ceramic balls, and C5 an internal radial clearance greater than standard. The ending S0 may refer to a special heat treatment for dimensional stability. These codes allow selecting the right bearing according to operating conditions.
These bearings are used in a wide variety of industries in Argentina, such as food, chemical, petrochemical and machine tool industries. Their ability to withstand high speeds and temperatures makes them suitable for electric motors, pumps, fans and compressors. They are also used in equipment where lubrication is critical or the environment is corrosive, thanks to ceramic balls that reduce wear and friction.
To select correctly, take into account radial and axial load, rotation speed and environmental conditions. The C5 internal clearance is useful when there are thermal differences between shaft and housing. The TN2 cage is suitable for high speeds, but verify compatibility with lubricants. During mounting, ensure precise alignment and avoid impacts that could damage the ceramic balls. Lubrication must be suitable for the cage type and service conditions.
Regarding equivalences, SKF bearings with these designations can be interchanged with products from other brands that meet the same dimensions and specifications. However, it is essential to verify the suffixes, as they indicate particular features such as ball material or internal clearance. Not all brands offer the same options, so we recommend consulting with our technical team before replacing a bearing.

Frequently Asked Questions
- What are the dimensions of the SKF 6311 TN2/HC5C5S0 bearing?
- The SKF 6311 TN2/HC5C5S0 bearing has a 55 mm bore, a 120 mm outside diameter and a 29 mm width (55 x 120 x 29 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6311.
- What does the HC5 suffix mean in an SKF bearing?
- The HC5 suffix indicates that the bearing incorporates silicon nitride ceramic balls. These balls are lighter and more corrosion resistant, which reduces friction and allows higher speeds. They are ideal for applications with limited lubrication or aggressive environments.
- When is a C5 internal clearance advisable?
- The C5 internal clearance is greater than standard and is recommended when there are significant thermal gradients between shaft and housing, or when high speeds are required. It helps compensate for expansion and prevents excessive preload that could damage the bearing.
- Can I replace an SKF TN2/HC5C5S0 bearing with another brand?
- Yes, as long as the other brand offers a bearing with the same dimensions and features: ceramic balls, C5 clearance and polyamide cage. It is important to verify the suffixes and consult a specialist to ensure compatibility and performance.
