Split spherical roller bearings

Unsplit spherical roller bearings with an adapter sleeve can be replaced by split spherical roller bearings. This gives a considerable reduction in the work associated with bearing replacement in numerous applications.

In order to ensure selection of the correct combination of housing and bearing when using split bearings, please contact Schaeffler.

The range of split spherical roller bearings is described in detail in a separate publication TPI 250.

Materials

Flake graphite cast iron as standard

Material for housing body:

  • flake graphite cast iron (standard)
  • spheroidal graphite cast iron
  • cast steel

Locating and non-locating bearings

Locating bearing arrangement by means of locating ring

The bearing seats in the housing are machined such that the bearings are movable in the housing and can thus function as non-locating bearings. Locating bearing arrangements can be achieved by the insertion of a locating ring FRM adjacent to the bearing outer ring.

Lubrication

Grease lubrication

Suitable lubrication method:

  • grease lubrication

Sealing

Felt seals

Plummer block housings S30 are sealed by means of felt seals ➤ Figure. The felt seals allow shaft misalignment of up to 0,5° in both directions and are suitable for grease lubrication.

The oil-soaked felt strips must be inserted in the associated slots in the housing. In the case of a housing closed on one side, 2 felt strips are inserted, while 4 felt strips are necessary in the case of a continuous shaft.

Covers DK made from polyamide

In the case of a housing closed on one side, a cover DK is inserted in the slots can be inserted instead of the felt strips on one side of the housing. Covers DK are made from polyamide.

Scope of delivery

When ordering split plummer block housings S30, the housing designation only describes the housing body. The felt strips for sealing the housing are included in the scope of delivery, while the cover and locating rings must be ordered separately. The rolling bearing and, if necessary, the adapter sleeve must also be ordered separately.

Split spherical roller bearings

In the replacement of bearings, the unsplit spherical roller bearings can be replaced by split spherical roller bearings 222S. This gives a considerable reduction in the work associated with bearing replacement in numerous applications.

In order to ensure selection of the correct combination of housing and bearing when using split bearings, please contact Schaeffler.

The range of split spherical roller bearings is described in detail in a separate publication TPI 250.

Materials

Flake graphite cast iron as standard

Material for housing body:

  • flake graphite cast iron to ASTM A48 Class 35 (standard)
  • spheroidal graphite cast iron to ASTM A536 Grade 65-45-12

The colour of the paint coating on housings made from flake graphite cast iron is grey (colour RAL 7016, anthracite grey), while on housings made from spheroidal graphite cast iron it is orange (colour RAL 2004, pure orange).

Locating and non-locating bearings

Locating bearing arrangement by means of locating ring

The bearing seats in the housing are machined such that the bearings are movable and can thus function as non-locating bearings. Locating bearing arrangements can be achieved by the insertion of a locating ring SR.

Lubrication

Grease or oil lubrication

Suitable lubrication methods:

  • grease lubrication
  • oil lubrication

Sealing

For sealing of the bearing housings, the standard seals available are the labyrinth seal and the Taconite seal ➤ Table. These seals are matched to the rectangular section annular slots on both sides of the housings.

Labyrinth seals LER

Labyrinth seals LER give non-contact sealing. They are therefore suitable for high speeds. The O ring, which is pressed between the labyrinth ring and shaft, is made from NBR and is suitable for temperatures of up to +100 °C.

Labyrinth seals allow shaft misalignment of up to 0,3° in both directions and are suitable for grease lubrication. If necessary, the labyrinth can be relubricated. For this purpose, a lubrication hole must be made in the upper housing section for each labyrinth seal. The optimum positions are indicated by cast-in pilot holes on the top of the housing.

Taconite seals TA

Taconite seals TA comprise two rings, of which one is located in the housing and the other on the shaft. An axial and a radial labyrinth is formed between these rings, where the effectiveness of the latter is increased by means of two spiral rings. Due to the non-contact sealing, Taconite seals are suitable for high speeds. The two statically acting O rings are made from NBR and are suitable for temperatures of up to +100 °C.

Taconite seals are designed for extreme operating conditions characterised by heavy contamination and the impact of abrasive particles.

Taconite seals allow shaft misalignment of up to 0,3° in both directions and are suitable for grease lubrication. For relubrication, the seal is fitted with a lubrication nipple.

Split labyrinth seals LERS

For plummer block housings SAF, labyrinth seals are also available in a split design. As a result, the work involved in replacing the seal can be considerably reduced.

Split Taconite seals TAS

For plummer block housings SAF, Taconite seals are also available in a split design. As a result, the work involved in replacing the seal can be considerably reduced. Split Taconite seals are not standard seals and are available by agreement.

Covers EC

Covers EC are used with housings closed on one side. The covers fit in the rectangular section annular slots in the housings. They are suitable for temperatures up to +100 °C.

Housing designs with and without cover

Plummer block housings RLE of design A are intended for the bearing arrangements of shaft ends. One side is closed by a cover and the other side is sealed against the shaft. Design B is intended for continuous shafts, in which case the housing is sealed against the shaft on both sides.

Labyrinth rings with felt seal

The seal is a combination of a labyrinth seal and a felt seal ➤ Figure. The labyrinth is separated from the grease cavity in the housing by oil-soaked felt strips, so a more economical grease can be used for labyrinth lubrication.

The labyrinth rings are unsplit. The seal allows shaft misalignment of up to 0,5° in both directions.

Combined seals comprising felt seal and V ring

Plummer block housing units VRE3 are sealed on both sides by a combined seal comprising a felt seal and V ring ➤ Figure. As a result, effective sealing against the ingress of contamination and the escape of lubricant is achieved. The oil-soaked felt strips are inserted in the slots in the covers on the housing. The external V rings are made from NBR and are suitable for temperatures of up to +100 °C. If a circumferential velocity of more than 8 m/s is present, axial support of the V rings is necessary. At or above 12 m/s, the seal lip lifts and the V ring then acts as a splash ring.

In flanged housings F112, the self-aligning ball bearing is clamped between the abutment shoulder in the housing and the cover. As a result, the bearing acts as a locating bearing.

Lubrication

Grease lubrication

Suitable lubrication method:

  • grease lubrication

Sealing

Felt seals

Flanged housings F112 are sealed by means of felt seals ➤ Figure. The felt seals allow shaft misalignment of up to 0,5° in both directions and are suitable for grease lubrication. The oil-soaked felt strips must be inserted in the associated slots in the housing.

Locating and non-locating bearings

Locating bearing arrangement by means of locating rings

The bearing seats in the housing are machined such that the bearings are movable and can thus function as non-locating bearings. Locating bearing arrangements can be achieved by the insertion of locating rings. For housings F505 to F513, locating rings FE are used, while for housings F515 to F522, locating rings FRM are used. The quantity of locating rings required is 1 or 2. Two rings are inserted on both sides of the bearing, while a single ring is inserted on the side with the adapter sleeve nut.

Lubrication

Grease lubrication

Suitable lubrication method:

  • grease lubrication

Sealing

Housing designs with and without cover

Flanged housings F5 of design A are intended for the bearing arrangements of shaft ends. One side is closed by a cover and the other side is sealed against the shaft. Design B is intended for continuous shafts, in which case the housing is sealed against the shaft on both sides.

Felt seals

Flanged housings F5 are sealed by means of felt seals ➤ Figure. The felt seals allow shaft misalignment of up to 0,5° in both directions and are suitable for grease lubrication. The oil-soaked felt strips must be inserted in the associated slots in the housing.
