Single Row7204 AC for Tractor part Angular contact ball bearing
1. Double row angular contact ball bearings with filling slot are
designed with special S shape or crown type of cages. Without
changing mounting dimensions, the structure effectively increase
the number of steel balls as to enhance the carrying capacity of
ball bearings with easy structures.
2. Double row bearings with notches have a filling slot on both
inner ring and outer ring, containing more steel balls than normal
double row angular contact ball bearings, so that their radial load
capacity are better than double row angular contact ball bearings'.
Thus, double row bearings with notches can bear large radial load
but with low speed limit.
Types:
Angular contact ball bearings are produced in a wide variety of
designs and sizes.Those commonly used and included in this
catalogue are:
1.Single-row angular contact ball bearings
Axial load in single direction can be sustained. While supporting
pure radial load, the bearings must be installed and used in pairs
since the line of action of the rolling element load is not in the
same plane as that of the radial one, resulting in inner separate
force.
2.Double-row angular contact ball bearings
This is basically a back-to-back mounting of two single-row angular
contact ball bearings, but their inner and outer rings are each
integrated into one. Axial loads in both directions can be
sustained, and the capacity to sustain moments is good. This type
is used as fixed-end bearings. Their cages are pressed steel.
3.Four-point angular contact ball bearings
The inner ring is split radially into two pieces. Their design
allows one bearing to sustain significant axial loads in either
direction. The contact angle is 35°, so the axial load capacity is
high. This type is suitable for carrying pure axial loads or
combined loads where the axial loads are high. The cages are made
of machined brass.
They are mainly used for steel industry,mining&construction,papermaking machinery, wind turbines,semiconductors,machine tools,gearboxes,electric motors,pumps&compressors,injection moldingmachines.
