SES528-L FAG Split Plummer Block Housing

SES528-L FAG Split Plummer Block Housing

SES528-L FAG is a split plummer block housing from the Schaeffler SES series, designed for industrial bearing arrangements using suitable rolling bearings with a 250 mm outside diameter. The modular SES housing concept allows different bearing types, sealing systems, locating rings and end covers to be combined according to the shaft arrangement and operating requirements.

Technical Data - FAG SES528-L

What Is FAG SES528-L?

The SES528-L is a bearing housing, not a bearing.

Its purpose is to support and locate a suitable rolling bearing within an industrial shaft arrangement while providing the structure required for sealing, lubrication and mounting to the machine frame.

The split housing consists of an upper and lower section. This design makes installation, inspection and maintenance considerably easier in large industrial bearing arrangements because the shaft does not necessarily need to be removed simply to gain access to the bearing.

FAG SES Series

Schaeffler developed the SES series as a modular split plummer block housing system.

A single housing size can be combined with different bearing designs provided that the selected bearing and all associated components are compatible with the housing.

The complete arrangement can therefore be configured according to:

• bearing type

• shaft diameter

• bearing bore design

• mounting method

• adapter sleeve

• sealing system

• axial location

• lubrication requirements

• operating environment

This modular concept is particularly useful for maintenance and industrial engineering applications.

Bearings for FAG SES528-L

According to Schaeffler selection data, SES528-L can be used with suitable bearings from several series, including:

20228

22228

23228

6228

These bearing arrangements use a bearing outside diameter of:

D = 250 mm

However, these bearing types are not automatically interchangeable.

The complete arrangement, including shaft diameter, bearing bore, adapter sleeve, seals and locating components, must be selected for the particular bearing being installed.

SES528-L with a 22228 Bearing

One important configuration combines:

SES528-L

with a spherical roller bearing from the:

22228 series

For a locating-bearing arrangement using a 22228 bearing, Schaeffler specifies the locating ring:

FRM250/15

The complete arrangement nevertheless depends on the exact bearing version and mounting method.

SES528-L with FAG 22228-E1-K

The SES528-L housing can form part of a bearing arrangement using a spherical roller bearing from the 22228 family.

When a tapered-bore bearing such as:

FAG 22228-E1-K

is used, the bearing can be mounted with an appropriately selected adapter sleeve.

The nominal bore diameter of the tapered bearing should therefore not automatically be interpreted as the shaft diameter when an adapter sleeve is used.

The bearing, sleeve, shaft and housing must be treated as a complete system.

Modular Housing Design

The modular construction of the SES series allows the housing to be combined with suitable accessories.

A complete bearing arrangement may include:

• SES528-L housing

• rolling bearing

• adapter sleeve where required

• locating ring

• sealing elements

• end cover for a shaft-end arrangement

• lubrication components

This allows the housing arrangement to be adapted to different machine and environmental requirements.

Dimensions of FAG SES528-L

Important housing dimensions include:

Base length a: 500 mm

Overall height h1: 302 mm

Housing width g: 205 mm

Shaft centre height h: 150 mm

Base width b: 150 mm

Bearing seat width K: 98 mm

Mounting hole spacing m: 420 mm

These dimensions are important when replacing an existing housing or designing the surrounding machine structure.

Bearing Seat

SES528-L is designed for suitable bearings with an outside diameter of:

250 mm

This dimension refers to the outside diameter of the bearing and must not be confused with the shaft diameter.

The required shaft diameter depends on the selected bearing and its mounting arrangement.

What Does L Mean?

The L version is the standard housing manufactured from:

flake graphite cast iron

This material is widely used for industrial plummer block housings and provides the robust housing structure required for many stationary industrial bearing arrangements.

Housing Mounting

SES528-L has a base designed for secure attachment to the supporting machine structure.

Important mounting dimensions include:

Mounting hole spacing: 420 mm

Recommended mounting bolts: M30

Mounting slot width: 35 mm

Mounting slot length: 42 mm

Correct positioning and alignment of the housing are important for reliable operation of the complete bearing arrangement.

Lubrication

The SES housing concept provides facilities for supplying lubricant to the bearing arrangement.

The correct lubricant, lubricant quantity and relubrication interval depend primarily on:

• installed bearing

• operating speed

• bearing load

• temperature

• contamination

• sealing arrangement

• operating environment

Lubrication requirements should therefore be determined for the complete bearing application rather than for the housing alone.

Sealing Options

SES528-L does not define one universal sealing system.

The modular SES concept allows different sealing arrangements to be selected according to the operating environment.

Seal selection can depend on:

• shaft speed

• contamination

• dust

• moisture

• operating temperature

• maintenance requirements

• surrounding environment

When ordering, it is therefore important to determine whether only the housing is required or whether the complete arrangement should also include seals and additional accessories.

Locating and Non-Locating Bearing Arrangements

In bearing systems with two support points, one bearing is commonly configured as the locating bearing while the second position allows axial displacement resulting, for example, from thermal expansion of the shaft.

Locating rings are used where the bearing outer ring must be axially located within the housing.

For an SES528-L arrangement using a 22228 bearing, Schaeffler specifies:

FRM250/15

The exact locating/non-locating arrangement must always correspond to the machine design.

Advantages of a Split Plummer Block Housing

The split construction provides important practical advantages in industrial machinery.

These include:

• easier bearing installation

• easier bearing inspection

• improved maintenance access

• easier replacement of internal components

• modular selection of bearings and seals

• robust support for large bearing arrangements

For large bearings, this can significantly simplify maintenance compared with arrangements requiring extensive shaft disassembly.

Typical Applications

SES split plummer block housings are intended for industrial bearing arrangements requiring robust shaft support and service-friendly construction.

Depending on the complete engineering design, they can be used in:

• conveyor systems

• industrial fans

• material-handling equipment

• production machinery

• industrial processing equipment

• drive systems

• heavy machinery

• large shaft-support arrangements

Suitability for a specific machine must be determined from the complete bearing arrangement and operating conditions.

How to Select FAG SES528-L

Before ordering, verify:

1. Complete housing designation SES528-L.

2. Required bearing type and designation.

3. Bearing outside diameter of 250 mm.

4. Shaft diameter.

5. Cylindrical or tapered bearing bore.

6. Adapter sleeve requirement.

7. Required sealing system.

8. Locating or non-locating bearing position.

9. Locating ring requirement.

10. End cover requirement.

11. Lubrication arrangement.

12. Machine mounting dimensions.

The housing designation alone does not define the complete bearing unit.

SES528-L vs Complete Bearing Unit

This distinction is particularly important when purchasing replacement components.

SES528-L identifies the housing.

A complete bearing arrangement may additionally require:

bearing + adapter sleeve + locating ring + seals + end cover + mounting and lubrication components

The exact configuration should therefore be checked against the existing machine arrangement or Schaeffler selection documentation.
