china high precision spherical roller bearings manufacturers
The inner ring of spherical roller bearings have two raceways,
outer raceway is a part of a sphere, whose curvature center is on
the axis of bearings. This type of bearings possesses self-aligning
performance, allowing the misalignment of shaft, and can also be
used under certain permanent misalignment. These bearings are able
to carry higher radial loads, as well as certain axial loads, but
can’t be used to carry pure axial loads. The osculation between
rollers and raceways is high, and friction is higher than
cylindrical roller bearings. Therefore, the limiting speed is
lower. This type of bearings is especially suitable to the heavy or
vibrating load applications. The type 20000C bearings have
symmetrical rollers and pressed steel cages, no rib on inner ring,
rollers are longer, load carrying capacity is high, and rollers are
guided by a floating guide ring. The type 20000CC bearings are the
modified type to type 20000C, the friction between rollers and
raceway is decreased, load carrying capacity is enhanced. The type
20000CA bearings adopt symmetrical spherical rollers and machined
solid cages, they have floating guide ring and integral ribs on
inner rings. The type 20000TN1 bearings use symmetrical rollers and
nylon molded cages, no integral ribs and floating guide ring on
inner ring, the cages are guided by rollers. The type 20000CC,
20000CA and 20000TN1 bearings are developed in recent years and
their internal design are optimized, should give priority to be
used. Spherical roller bearings are primarily used in the
applications, such as rolling mills, paper-making, power
transmitting equipments and ship mechanics, gearbox,
vibratory,Metallurgical Mining and construction Fluid machinery
