Cylindrical roller and race for line contact bearing. Load
capacity is big, mainly bear radial load. Roller and ring guard
friction small, suitable for high speed rotation. May according to
the ring presence of guard, NU, NJ, NUP, N, NF, such as single row
cylindrical roller bearings, double row cylindrical roller bearing
and NNU, NN and other. The bearing inner ring and outer ring is
separable structure. No guard of cylindrical roller bearing inner
ring or outer ring, internal ring and outer ring can be to relative
axial movement, so can be used as free end bearing. The one side of
the inner ring and outer ring with double guard, on the other side
of the ring has a single guard cylindrical roller bearing, can
withstand a certain degree of axial load in one direction. General
use of stamping steel cage, cage or copper alloy car system
entities. But there are also part of the use of polyamide forming
keep frame.
