Cylindrical roller bearing
Cylindrical roller bearings with inner or outer rings without
fenders, whose inner and outer rings can move relative to each
other in axial direction, can be used as free-end bearings.
Cylindrical roller bearings with double rim on one side of the
inner and outer rings and a single rim on the other side of the
ring can withstand a certain degree of axial load in one direction.
Generally used steel plate stamping cage, or copper alloy car solid
cage. But some use nylon forming cages.
Cylindrical roller and raceway for line contact bearings. Large
load capacity, mainly bearing radial load. The friction between the
rolling body and the rim of the ring is small, suitable for
high-speed rotation. According to whether the ring has a rim or
not, it can be divided into NU, NJ, NUP, N, NF and other single-row
cylindrical roller bearings, and NNU, NN and other double-row
cylindrical roller bearings. The bearing is a detachable structure
with inner ring and outer ring.
