The NSK UCFA2 is a flange-mounted bearing unit that supports rotating shafts on flat surfaces. A cast housing and a ball insert bearing come pre-aligned and pre-lubricated, so the unit is ready to bolt down. Four bolts secure the flange. This makes it a practical choice for power transmission where firm support and quick replacement matter.
The code breaks down into three parts. UCFA tells you it is a 4-bolt flange housing. The 2 is the diameter series. The number after that, as in UCFA201D1 or UCFA204-012D1, gives the bore size of the insert. D1 indicates the insert execution. When a hyphen appears, as in UCFA201-008D1, the digits after it are the bore size in inches. So UCFA201D1 and UCFA201-008D1 use the same housing but have different bore diameters.
You will find these units on belt conveyors, mixers, blowers, exhaust fans, packaging lines and process equipment in food, chemical and materials plants. They also show up in agricultural machinery and materials handling equipment. Anywhere a sturdy flange support with fast replacement is needed, this series is a common sight.
Selection depends on shaft diameter, load type and the environment. The insert seal determines whether the unit handles dust, water or frequent washdowns. Align the flange with the shaft to avoid lateral stress. Most inserts are lubricated for life, but check clearance and seal condition during mounting. Bolt the flange to a flat surface and turn the shaft by hand before start-up.
When replacing a housing from another brand, compare shaft diameter, hole spacing and overall height. The NSK UCFA2 series often interchanges with other brands using the same nomenclature, but always verify dimensions. At MR Industrial Accessories, we quote the exact code from your equipment or the measurement you provide.
MR Industrial Accessories supplies the NSK housing line and helps you pick the right variant. If the designation is unclear, send the full code via WhatsApp or email and we will reply promptly. We can also suggest a compatible alternative if you share the shaft and flange dimensions.

Frequently asked questions
- What does the D1 suffix mean in UCFA2 housings?
- D1 identifies a specific insert bearing execution. The flange dimensions stay the same, but sealing or lubrication may differ. Send the full code for an exact quote.
- How do I choose between a code with a hyphen and one without?
- Codes with a hyphen, such as UCFA201-008D1, are inch sizes. Those without, like UCFA201D1, are metric. Check your shaft diameter to decide. If unsure, message us on WhatsApp with the measurement.
- Can this housing replace one from another brand?
- Usually, 4-bolt flange housings with insert bearings interchange between brands if shaft diameter, hole spacing and height match. Compare those dimensions or send us the original code and we will indicate the equivalent.
