This SKF deep groove ball bearing is a standard component for moderate radial and axial loads, high-speed rotation and low maintenance. The 2RZTN9 sealing and C3 internal clearance make it a fit for applications where operating temperature is elevated and lubricant retention matters. MR Industrial Accessories supplies it and helps you confirm the right variant for your equipment.

The code breaks down into features you can read at a glance. The 2RZTN9 suffix means two low-friction RZ seals and a TN9 cage, which is polyamide reinforced with fiberglass. The slash separates the basic code from these additions. The /C3 suffix calls for internal radial clearance above standard, which suits interference fits or temperature differences between the inner and outer rings. For example, in 629-2RZTN9/C3, the 629 sets the size and the suffixes set the rest.

You will find this bearing type in electric motors, centrifugal pumps, fans, compressors, machine tools and transmission equipment. Its ability to run at high speeds with low noise makes it useful where precision and reliability are required. The 2RZTN9 sealing and C3 clearance combination is common in equipment that sees high temperatures or thermal cycling.

Selection depends on radial and axial load, speed, temperature and environment. The 2RZTN9 seal keeps out dust and moisture but is not intended for immersion. C3 clearance accommodates greater thermal expansion; if the fit is loose, standard clearance may be the better choice. During mounting, check shaft and housing alignment, use the right tools and lubricate to specification. Do not strike the seals, and make sure the bearing seats on the correct ring.

Interchange between brands is possible when dimensions, internal clearance and sealing type match. Alternatives from NSK, FAG, NTN or Timken may exist, but suffixes can differ, so verify tolerances and clearance. MR Industrial Accessories supplies SKF and can guide you on interchangeability without compromising equipment performance.
