Single row cylindrical roller bearings

Single row cylindrical roller bearings are designed for applications with high to very high radial loads and medium to high speeds. The JOJI product range comprises a wide range of designs and types, such as standard, full complement and high load capacity bearings. Depending on the construction of the inner and outer rings, the bearings are available in locating and non-locating designs.

  • High or very high radial load capacity
  • Very low friction
  • Long service life
