LHB produces cylindrical roller bearings in many designs, dimension series and sizes. The majority are single row bearings with a cage. Single and double row full complement bearings (without cage) complete the LHB standard assortment for general engineering. Bearings with a cage can accommodate heavy radial loads and operate at high speeds. Full complement bearings are suitable for very heavy radial loads at moderate speeds.The LHB range of cylindrical roller bearings comprises the basic types
,single row cylindrical roller bearings, caged, mainly of the NU, NJ, NUP and N designs ;double row cylindrical roller bearings, caged, mainly of the NNU and NN designs;multi-row cylindrical roller bearings, caged etc.
We can produce the diameter from 15mm~ 800mm LHB cylindrical roller bearings.Following is the internal structure of LHB different product descriptions.
