SKF ZTN series deep groove ball bearings with C3 and LHT suffixes are components designed to support radial and axial loads in applications requiring increased internal clearance and high-performance lubrication. Their construction includes a seal that protects against contamination and retains lubricant, making them suitable for demanding environments. MR Accesorios Industriales supplies this line as part of its SKF bearing range, with more than 80 years of experience in the industry.

The designation of these bearings combines several elements. The basic number, such as 6002, 6202 or 6203, indicates the size and dimension series. The ZTN suffix refers to the sealing type: the letter Z indicates a shield, TN indicates a synthetic material cage, and the final 9 refers to an internal variant. The C3 suffix specifies an internal radial clearance greater than standard, and LHT identifies a high-performance lubricant, generally synthetic grease for high temperatures. Thus, a 6203-ZTN9/C3LHT23 is a bearing of the 62 series, with Z shield, TN cage, C3 clearance and LHT grease.

These bearings are used in a wide variety of industrial equipment in Argentina. They are common in electric motors, pumps, fans, compressors and machine tools, where temperature and speed conditions require a stable lubricant and adequate clearance. They also appear in automotive applications, such as alternators and tensioners, and in power transmission equipment. Their ability to support combined loads and their sealing make them suitable for environments with dust or moderate humidity, typical of the manufacturing and process industries.

When selecting a bearing from this series, take into account the internal clearance: the C3 suffix indicates a clearance greater than standard, recommended for applications with interference fits or thermal differences between inner and outer rings. The ZTN seal offers protection against particles, but is not liquid-tight; for humid environments, consider variants with rubber seals. LHT lubrication is formulated for high temperatures and long life, but verify that it is compatible with the environment. During assembly, ensure correct alignment and avoid impacts that could damage the raceways. Cleanliness of the housing and shaft is essential to prevent contamination.

Regarding equivalences, SKF ZTN series bearings with C3 and LHT suffixes can be interchanged with products from other brands that follow the same standardized designations. However, additional letters may vary between manufacturers; for example, others use their own codes for synthetic material cages or special lubricants. Always verify critical dimensions and operating conditions before replacing one bearing with another of a different brand. MR Accesorios Industriales can advise you on the interchangeability of these references.
