Product Overview
  • 6311 is a single-row open deep groove ball bearing with dimensions 55×120×29mm. It features a wider cross-section and higher load capacity compared to 6211 series bearings. This bearing can withstand combined radial loads and bidirectional light axial loads. The standard version is open type, while sealed 6311-2ZR / 6311-2RSR can be customized. Made of high-purity GCr15 chrome bearing steel, it runs stably at medium speed and is widely used for medium-heavy industrial transmission equipment.
