SMR SN Series plummer block housings are standard split housings for self-aligning ball bearings and spherical roller bearings, designed for general engineering applications.
SMR SN Series plummer block housings provide a practical and economical housing solution for general engineering requirements.
The horizontally split construction allows convenient access for bearing installation, inspection, maintenance and replacement.
SN housings accommodate both cylindrical-bore and tapered-bore bearing arrangements. Cylindrical-bore bearings are mounted directly on the shaft, while tapered-bore bearings are mounted using suitable adapter sleeves.
The SN Series also provides flexibility in bearing mounting and axial-location arrangements to suit different installation requirements.
Horizontally split design for convenient bearing installation, inspection and maintenance.
Suitable for self-aligning ball bearings and spherical roller bearings with cylindrical or tapered bores.
Direct mounting for cylindrical-bore bearings and adapter-sleeve mounting for tapered-bore bearings.
Standard felt seals provide grease retention and protection against normal levels of dust and external contaminants.
Locating rings can be fitted where the bearing is required to be axially located within the housing.
Grease nipples are provided for convenient bearing relubrication.
Eye bolts are provided on larger housing sizes for easier handling during installation and maintenance.
Standard felt seals provide effective grease retention and protection against normal levels of dust and external contaminants.
Labyrinth seals can be supplied where enhanced protection against dust and external contamination is required.
SN Series housings are designed for grease lubrication. Grease nipples are provided for convenient bearing relubrication.
For particularly demanding environments, SMR recommends its advanced housing ranges specifically developed for challenging operating conditions.
For a fixed bearing arrangement, one or two locating rings can be fitted to provide axial location of the bearing, depending on the housing and bearing arrangement.
SMR SN Series plummer block housings are intended primarily for general engineering applications where bearings operate under moderate loads and speeds and within relatively clean and temperate environments.
For more demanding operating conditions, SMR offers advanced housing ranges with additional sealing, configuration and performance options suited to specific application requirements.
