I’ve been seeing more maintenance teams standardize on the UCFL205 Cast Iron Two Bolts Flange Housed Bearing lately—partly because it just works, partly because it’s easy to swap when the line is hot and you don’t have three hours to spare. Origin-wise, this unit comes out of No. 3, Area B, Bearing Industry Mass Entrepreneurship Park, Beihuan Road, Linxi County, Xingtai City, Hebei Province. That cluster has quietly become a global supply hub.
The format—two-bolt oval flange—mounts fast on sheet metal or plate. The UC205 insert is a wider inner ring style with set-screw locking, which, to be honest, is what most plant techs prefer for shafting that sees moderate vibration. Many customers say grease retention and seal life are better than they expected. In fact, for moderate dust and the usual splash zone, it’s a solid pick.
| Housing material | Cast iron (HT200/FC200), painted or phosphated |
| Insert | UC205 (AISI 52100/GCr15) with wide inner ring, 2 set screws |
| Bore (d) | 25 mm |
| Bolt size / centers | M10 (≈ 3/8"); centers ≈ 95 mm (real-world use may vary by vendor) |
| Dynamic/Static rating | C ≈ 14 kN; Co ≈ 7.8 kN (per ISO 281/ISO 76 methodology) |
| Speed limit (grease) | ≈ 5,000–6,000 rpm (application dependent) |
| Seals & grease | Contact rubber seals; NLGI #2 lithium complex as standard |
| Operating temp | -20 to 110 °C typical |
Housing is cast, normalized, and machined; insert rings are through-hardened to ~HRC 60–64. After assembly: grease charge, torque set-screws, and run-in. QC checkpoints generally include radial clearance check, seal drag, dimensional gauging, and salt-spray on coated samples (ASTM B117). Load ratings are calculated per ISO 281; static per ISO 76. Typical L10 service life under ~0.3C radial at moderate speed lands in the tens of thousands of hours—your mileage depends on misalignment and contamination.
- Light-to-medium conveyors (logistics, grain, recycling) • HVAC fan frames • Agricultural augers • Small quarry idlers • Packaging lines. Advantages? Easy alignment, replaceable insert, decent misalignment tolerance (~±2°), and a price point that won’t trigger a capex review.
Seal upgrades (triple-lip), food-grade grease, stainless sleeve, special coatings, and re-lube fittings. For wet or abrasive duty, ask for extra labyrinths or a taconite seal—seriously worth it.
| Vendor | Certs | Seal/Grease options | Lead time | Typical price |
|---|---|---|---|---|
| BTZ Bearing (Hebei) | ISO 9001 | Standard + custom seals; NLGI #2, food-grade | ≈ 7–15 days | ≈ $4–8/unit |
| Global Brand A | ISO 9001, ISO 14001 | Wide menu; premium greases | Stock to 10 days | ≈ $18–30/unit |
| Local Trader | Varies | Limited | Immediate | ≈ $3–5/unit |
Prices and lead times are indicative; specs may vary by manufacturer and lot.
A grain-handling site swapped 28 legacy flanges for UCFL205 Cast Iron Two Bolts Flange Housed Bearing units before harvest. Result: fewer stoppages (2 vs. 7 the previous season) and cleaner grease intervals (from weekly to every 3–4 weeks). Not a lab trial, but the maintenance log backs it up.
If you need a dependable, standard-duty mounted unit, UCFL205 Cast Iron Two Bolts Flange Housed Bearing is a safe bet. For corrosive washdown, I’d step up to stainless or a coated housing; otherwise, this will quietly earn its keep.
