Split spherical roller bearings

Update date: 2020-10-25 16:19　 Attention: | Inquiry entry: sales@fv-bearing.com 　

Split spherical roller bearings are primarily used for bearing positions which are difficult to access, such as for long shafts which are supported at several positions or for cranked shafts. Their use is also beneficial where non-split bearings require considerable extra effort and time for maintenance and particularly replacement which would cause long and expensive, or perhaps even inadmissible machine downtime. Split spherical roller bearings offer the optimum solution to such problems. The main application fields are conveyor equipment, converter bearing arrangements, long multiple-supported shafts as well as large ventilation plant.

Split spherical roller bearings are produced by FV to order. The design is tailored to the particular application and, for cost reasons, is generally based on available standard bearings. The selection of bearings shown in the tables is intended to illustrate the FV manufacturing capability by presenting bearings which have been made. Before finalising a bearing arrangement design incorporating a split spherical roller bearing it is advisable to consult the FV application engineering service.

Split bearing units for continuous casting plant

FV has developed ready-to-mount split bearing units specifically designed for use on the drive rollers in the cooling zone of continuous casting plant. The special housings are of cast steel and are water cooled. The housing top with its integral cooling chamber has a low sectional height because the standard design incorporates only one bearing outer ring half which is placed in the base of the housing. The spherical roller bearing of the unit normally consists of two inner ring halves with lubrication groove and holes, four clamping ring and cage halves, one outer ring half and two lamellar sealing rings with one split. The inner ring division is at an angle to the bearing axis.

Further information on FVsplit bearing units for continuous casting plant will be sent on request.

Designs

As already stated, FV split sherical roller bearings are based for the most part on non-split bearings of standard design. Consequently they represent state-of-the-art engineering. All the split bearings have a cylindrical bore and an annular groove and lubrication holes in the outer ring to facilitate efficient lubrication. The joins of the inner rings are at an angle to the bearing axis in order to guarantee uninterrupted over-rolling of the join. The bearing rings and cage are divided in the middle and the ring halves are held together either by screws or by clamping rings.

BSR.1 design Inner ring screwed together. Two integral retaining flanges. Split inner ring centred machined brass cage.
BSR.2 design Inner ring with two integral retaining flanges. Loose split clamping rings. Split inner ring centred machined brass cage.
BSR.3 design Inner ring with two integral retaining flanges. Loose split clamping rings. Split machined pin-type cage of steel.

Dimensions

The dimensions of split spherical roller beanngs have not been standardised.

Misalignment

Split spherical roller bearings are selfaligning and permit angular misalignments of the shaft relative to the housing of some 1 to 1.5 .
