The SNR USF series is a Y-bearing unit that combines a 4-bolt flange housing with an insert bearing, supplied as a single pre-assembled component. It is designed for straightforward installation on flat surfaces and supports rotating shafts in equipment where stable mounting and basic alignment are required. The insert bearing can be replaced without removing the housing, simplifying maintenance.

The code structure of the USF series provides key information. The number following the letters indicates the shaft diameter and housing size. For instance, USF204 and USF205 correspond to different metric shaft sizes. Variants such as USF204-12, USF205-14, USF205-15, and USF205-16 use the same housing body but have an insert with an inch-sized bore. The suffix after the hyphen denotes the bore size in sixteenths of an inch.

These flange units are used across various industrial applications, including conveyors, elevators, mixers, blowers, exhaust fans, and packaging machinery. They are particularly suitable for environments with dust, moisture, or frequent washdowns, such as food processing, cement, and metalworking facilities. The four-bolt design allows mounting on sheet metal, structural profiles, or flat concrete bases, while the insert bearing tolerates minor misalignment from assembly.

When selecting a USF unit, begin with the shaft diameter and the insert locking mechanism. Options include set screws, eccentric locking collars, or tapered adapter sleeves. Sealing is another consideration: in wet or dusty conditions, a single or double lip seal is recommended. The bearing arrives pre-lubricated, but periodic greasing is necessary based on operating conditions. During installation, ensure the flange rests on a clean, flat surface, tighten the bolts in a cross pattern, and check that the shaft rotates freely to maximize insert life.

For replacements or cross-referencing, compare the shaft size, flange outer diameter, bolt hole spacing, and insert locking type. These dimensions often match across brands, though sealing and locking systems may differ. At MR Industrial Accessories LLC, we can help identify a compatible alternative or quote the exact SNR part you need.

Frequently asked questions

How do I interpret the suffix in USF part numbers like -12 or -14?
The number after the hyphen indicates the insert bore in inches, expressed in sixteenths. For example, USF204-12 has an insert for a 12/16 inch shaft, while USF204 without a suffix is for a metric shaft. This allows the same housing to accommodate different shaft sizes.
What should I check to determine if a USF housing from another brand is interchangeable?
Compare the shaft diameter, flange outer diameter, bolt hole spacing, and insert locking type. If these match, the mounting is typically interchangeable. Send us the original part number and we can confirm the equivalent.
How should I lubricate the insert bearing in a USF unit?
The insert is factory-lubricated. In service, re-grease according to operating conditions—more often in high temperatures, high humidity, or dusty environments. Use a medium-consistency grease and avoid mixing different bases.
