Schaeffler Plummer Block Housings

Schaeffler FAG provides two design assemblies, split and unsplit plummer block housings that have proven successful in machinery, plant and equipment. Typically made from predominately cast iron, however, the FAG bearing housings can be supplied in cast steel or spheroidal graphite cast iron if required.

Split plummer block housing designs have a simplified assembly with the have the ability of the upper part of the housing to be removed. This allows for easy maintenance.

Unsplit plummer block housings are used in applications that require high demands on bearings.

Split Plummer Block Housings LOE

The FAG LOE series is designed to support high-speed bearing arrangements in heavy-duty industrial applications, such as fans, conveyors, and processing equipment. Engineered for oil lubrication, these split housings ensure efficient heat dissipation and reliable performance under demanding conditions. Their modular construction offers flexibility in design, allowing for both locating and non-locating arrangements, and for use on shaft ends or continuous shafts.

Constructed from robust materials including flake graphite cast iron as standard, the LOE housings feature optional upgrades to spheroidal graphite cast iron or cast steel to suit specific operating environments. Integrated labyrinth seals allow for shaft misalignment and provide reliable sealing against contamination. Additional options such as internal cooling coils and precision-machined bearing seats further enhance performance and service life.

• Designed for oil lubrication to suit high-speed applications
• Available in a wide range of shaft sizes and bearing configurations
• Robust housing materials with anti-corrosion coating
• Optional cooling coil for enhanced thermal management
• Labyrinth seal design supports shaft misalignment and relubrication

Split Plummer Block Housings SES

The FAG SES series is a compact and cost-effective bearing housing solution ideal for use with grease-lubricated spherical roller bearings. Its split design ensures easy mounting and dismounting, even in tight installation spaces, while maintaining excellent reliability for standard-duty industrial applications. SES housings are especially suited for applications with lower to medium operating speeds and loads.

Manufactured from robust grey cast iron and featuring a compact footprint, SES housings help reduce both weight and installation time. The housing supports flexible mounting arrangements and includes dual-lip contact seals to effectively retain lubrication and protect against contamination. All units come pre-machined and ready for immediate installation.

• Designed for grease lubrication with spherical roller bearings (Series 222)
• Compact and economical design ideal for standard-duty applications
• Made from durable grey cast iron with contact seals for effective sealing
• Split housing for easy installation and maintenance
• Supplied ready to mount, with optional locating rings and end covers available

Split Plummer Block Housings SNS

Split plummer block housings SNS are highly robust and therefore particularly suitable for aggressive environmental conditions such as those in mining applications.

The housings are designed in accordance with a modular concept. Each housing can be fitted with rolling bearings of various diameter and width series if they have the correct outside diameter for the housing.

• Designed in accordance with a modular concept and are highly versatile in application 
• Suitable for different bearing types and sizes with bore diameters from 115 mm to 530 mm 
• Lead, as a result of their design, to optimised load distribution and thereby increase the rating life of the bearing by up to 50% 
• Give a reduction, due to the lower replacement frequency of the bearing fitted, in total costs over the running time

Split Plummer Block Housing SNV

Split plummer block housings SNV and the associated bearings form bearing arrangement units that can be matched, through the appropriate selection of accessories, to a wide range of applications. Applications include agricultural machinery, the paper processing industry, mining, materials processing, the steel industry and power stations.

The housings are designed in accordance with a modular concept. Each housing can be fitted with rolling bearings of various diameter and width series if they have the correct outside diameter for the housing.

• Designed in accordance with a modular concept and are highly versatile in application
• Suitable for different bearing types and sizes with bore diameters from 20 mm to 160 mm 
• Can be combined with an extensive range of seals covering a wide range of requirements and temperatures
