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.
Dimension
Overall dimension of split cylindrical roller bearing is not standardized yet.
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"
Tolerance
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.
Internal clearance
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 dynamic load".
Speed
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.
