Split cylindrical roller bearing is mainly used for crankshaft and where it is difficult to
reach.When it is difficult to m,maintain and replace integral
cylindrical bearing or stop equipment, split cylindrical roller
bearing shows its superior.Its main application is crank
shaft/ratchet shaft of pige steel pipe,excavator, drive shaft of
rolling mill as as well as large sized ventilation equipment .SATA
have successfully developed split cylindrical roller bearing,which
can be installed at any time, to meet requirements of transmission
bearing in cool unit of continuous casting equipment.
Double row split cylindrical roller bearings
Double row split cylindrical roller bearing is developed initially
for transmission bearing.Two halve outer rings are installed inside
bearing seat is connected each other or by using several keys to
prevent it rotation.Its split inner ring section forms a included
angle to central line of bearing to makes bearing rotated stably
and connected via clip.Split brass cage is positioned through
roller.Its axial clearance shall meet heat expansion requirement of
cardan axis length.
Overall dimension of split cylindrical roller bearing is not
Angular alignment tolerance in axial direction
For single row and double row split cylindrical roller bearing,
there are one"logarithm curving contact surface between roller and
raceway, which can effectively improve stress distribution inside
bearing and allow minor angular alignment tolerance:"2"
Split cylindrical roller bearing is manufactured according to standard tolerance level.But its
inner ring, outer ring width tolerance are exceptional.Its standard
tolerance shall accord to ISO0492-1986.
Split cylindrical roller bearing is machined according to standard
level and value shall accord to ISO5753-1991.
Load bearing capacity
Because roller is less in quantity,its bearing capacity is lower
than integral bearing.
In calculating equivalent dynamic load, considering shall be taken
not to let roller exceeding raceway connection.This value is
subjecte to working condition.Please refer to section "equivalent
Due to split reason,vibrating occurs during operation, which limit
its speed performance accounting 50% of integral bearing,Such a
value can not meet demand of client.Please consult with SATA
technical service department for proper improvement.
