SNA Stainless Steel Insert Bearing Series
SNA is a standard duty series configured around stainless steel bearing insert, wide inner ring. Its catalogue definition uses eccentric locking, with individual bore and dimensional variants retained in one model table.
Series Overview
The catalogue treats this as a distinct series, so the page below follows the same logic: choose the series by housing and locking arrangement, then match the exact unit number and dimensions in the supplied table.
If the machine layout is not fixed yet, compare this family with other mounted-bearing formats before choosing the model row. Housing geometry usually narrows the options faster than bore size alone. Browse related bearing families.
Series-Level Selection
SNA is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
Mounting Form
The primary configuration is stainless steel bearing insert, wide inner ring, intended for stainless insert selection for corrosion-sensitive housings and mounted units.
Environment
Stainless steel insert; food-grade grease and silicon rubber seal stated in catalogue. Confirm the selected insert, seal, grease and cover arrangement for the actual cleaning or corrosion exposure.
Technical Specifications
Use these identifiers as the first selection gate. They capture the catalogue family, duty, locking and mounting form, while the numerical model rows remain grouped in the source table below.

Engineering Drawing
When replacing an installed unit, use the outline drawing as a dimensional fingerprint. Match the fixed machine dimensions before relying on a partially legible model code or a visually similar housing.
Applications
Washdown mounted units
SNA is relevant when washdown mounted units requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
Food and packaging equipment
For food and packaging equipment, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
Corrosion-sensitive bearing housings
SNA is relevant when corrosion-sensitive bearing housings requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
Catalogue Dimensional Data
The dimensional data is retained as one complete source table. This is especially useful when adjacent sizes share a housing but differ in shaft, inner-ring or mounting dimensions.
Selection & Integration
Begin with the machine mounting envelope, then confirm the shaft and locking arrangement. A similar series code does not guarantee the same center height, bolt pattern, cartridge fit, slot geometry or inner-ring dimensions. In this family, the intended role is stainless insert selection for corrosion-sensitive housings and mounted units.
| Step | Information To Confirm |
|---|---|
| 1 | shaft diameter |
| 2 | housing compatibility |
| 3 | locking method |
| 4 | seal, grease and cleaning requirements |
The model code should be verified together with its dimensional row. This is particularly important where metric and inch variants share similar housings but differ at the shaft interface.

Confirm The Exact SNA Configuration
For a faster series check, include the installed unit code when available, plus shaft size, quantity and a photo or drawing of the mounting interface. Ever Power Netherlands Branch can review the quotation basis against the same reference.
