Versatile and Durable Design

The SN 30 Series Bearing Housing is meticulously engineered using high-grade cast iron for strength and longevity. Its corrosion-resistant coating protects against harsh industrial environments, while the precisely machined finish ensures dependable alignment. With a foot-mounted structure, the housing guarantees secure installation on various machine frames. The removable cap allows for quick inspection and maintenance, reducing machine downtime.

Efficient Maintenance and Operation

Maintenance is simplified thanks to the split-type housing with a removable top cap and a re-lubrication provision, making it easy to service bearings without full disassembly. Double lip seals keep contaminants away from lubricated surfaces, improving operational life. An anti-rotation pin provides added stability, while optional end covers further shield components from dust and debris, supporting reliable long-term performance.

Product Description

SN Series Plummer Blocks

The SMR SN Series is a standard, horizontally split plummer block housing designed for moderate load and speed applications where reliability, ease of maintenance, and cost efficiency are important.

It is a widely accepted housing design used in stable operating conditions where grease lubrication and straightforward installation are sufficient.

What the SN Series Is Best Suited For

The SN Series is typically selected when:

Operating loads and speeds are moderate
The application environment is relatively clean
Grease lubrication is preferred
A proven, uncomplicated housing design is required

This makes the SN Series a practical choice for many general industrial installations.

How the Housing Works

The split construction allows the bearing to be installed, inspected, or replaced without removing the shaft, simplifying both initial installation and routine maintenance.
The housing is designed to provide axial freedom to the bearing, allowing for shaft expansion during operation.
When axial location is required, it can be achieved by fitting one or two locating rings, depending on the application.

Bearings, Lubrication & Sealing

The SN Series is primarily intended for adapter sleeve-mounted spherical roller bearings and is designed for grease lubrication.
Standard felt seals provide basic protection against dust and contaminants, making the series suitable for clean and temperate environments.
Oil lubrication and heavy sealing arrangements are not intended for this series.

Material & Compatibility

SMR SN Series plummer blocks are manufactured from graded cast iron and follow established international dimensional standards, allowing easy interchangeability with standard SN housings. SN series housings can be manufactured in S.G. Iron and Cast Steel if required.

A Simple Selection Note

Choose the SN Series when you need a reliable and economical plummer block for moderate operating conditions.
For higher loads, enhanced sealing, or more demanding environments, SMR offers SNA, SNH, and SNL series housings.

Technical Details

Exact dimensions, shaft sizes, bearing compatibility, and accessory options are provided in the SMR SN Series catalogue.

SMR can assist in confirming the most suitable housing and bearing arrangement for your application.
