Split Plummer Block - SN Series

Standard General Engineering plummer blocks

SMR SN series plummer blocks are designed for general engineering applications where bearings are subjected to moderate loads and speeds and work within relatively clean and temperate environments.

SN housings are of the split type and are standard-equipped with felt seals. For housings where bearings are to be axially located, locating rings can be inserted. Horizontal labyrinth seals can also be supplied on request.

Shaft diameters 20 - 200 mm
Suitable for moderate loads and speeds
Split structure for easy bearing mounting
Felt strip seals standard configuration
Labyrinth seal option for dusty areas
Locating rings for axial location

Key Features

Split plummer design

Enables easy installation and maintenance of the bearing and shaft assembly.

Felt Strip Seals

Provided as standard. Very effective for grease retention and dust exclusion in clean environments.

Axial Location Rings

Locating rings can be inserted to secure the bearing axially in the housing seating.

Labyrinth Option

Can be supplied with horizontal labyrinth seals for use in dusty or dirty environments.

Sealing Options

01
Felt Seals

FS type felt strips - economical grease retention in clean, dry environments.

02
Labyrinth Seals

Metal labyrinth rings - recommended for high speeds and dusty atmospheres.

03
Locating Rings

Locating rings used to create a locating (fixed) bearing arrangement.

04
Grease Nipples

Grease nipples can be fitted on the cap on request for relubrication.
