12mm UCFB201-8 Flange bracket Unit bearing | Heavy-Duty


Field notes on a compact workhorse: 12mm UCFB201-8 Flange bracket Unit bearing

If you spend time around conveyor lines or compact farm kit, you’ve seen this unit a thousand times. It’s small, modest, and—honestly—surprisingly resilient when made right. I visited the origin plant at No. 3, Area B, Bearing Industry Mass Entrepreneurship Park, Beihuan Road, Linxi County, Xingtai City, Hebei Province; the vibe was pragmatic: build it strong, test it hard, ship it fast.

What it is (and why it sells)

The 12mm UCFB201-8 Flange bracket Unit bearing is a bracket-style mounted unit—compact footprint, easy to bolt on, with a 12 mm bore insert. Many customers say they choose it for quick swaps on packaging lines and greenhouse fans. To be honest, the value-for-money equation is the hook.

Core specs at a glance

Bore 12 mm (nominal)
Unit Type UCFB201-8 flange bracket with set-screw locking
Housing Cast iron, paint-coated; grease nipple fitted
Insert UC201 series, steel (GCr15); double-lip contact seals
Dynamic rating (C) ≈ 7–12 kN (application-dependent; real-world use may vary)
Operating temp -20 °C to +120 °C with standard lithium grease
Shaft fit h7 recommended; set screws ≈ 120° apart

Process flow and testing (quick but not sloppy)

  • Materials: rings from GCr15 bearing steel; housing from HT200 cast iron; seals NBR; bolts graded per GB/T standards.
  • Methods: forging → turning → heat treatment → grinding (raceway) → phosphating/paint → assembly → grease fill.
  • Testing: radial internal clearance per ISO 5753-1; tolerance check vs. ISO 492; salt spray ASTM B117 (72–120 h typical); grease endurance ASTM D3336 sampling; noise/vibration ISO 15242 screening.
  • Service life: L10h estimated by ISO 281—often 20,000–40,000 h at moderate loads; field conditions vary.
  • Certs: ISO 9001 QMS; RoHS and REACH compliance statements available.

In our lab peek, runout sat around ≤10 μm on samples; not aerospace, but perfectly fine for conveyors. Grease purge felt clean—no frothing. I guess that’s why maintenance techs keep reordering.

Where it’s used (and what people say)

Applications: light conveyors, carton erectors, greenhouse ventilation, compact ag implements, food-pack (non-washdown), small CNC routers. Feedback is consistent: “easy to align,” “takes dust well,” “grease stays put.” One bottling line in Shandong swapped legacy hangers for 12mm UCFB201-8 Flange bracket Unit bearing units and cut unplanned downtime by ≈18% over a quarter—mostly thanks to steadier seals and better grease retention.

Customization options

  • Bore range ≈ 10–20 mm; inch bores on request.
  • Locking: set-screw standard; eccentric collar optional.
  • Materials: stainless insert (SUC201) and triple-lip seal for damp areas.
  • Grease: food-grade H1 or low-temp arctic blends.
  • Private label and batch traceability QR codes.

Vendor snapshot (what you’ll likely notice)

Factor BTZ Bearing Local Distributor Import Marketplace
Lead time ≈ 7–15 days Same-day if stocked ≈ 10–30 days
Customization Wide (seals, grease, labels) Limited Varies wildly
Certs/traceability ISO 9001; batch reports On request Not always clear
Price (ex-works) Competitive Moderate–High Low–Mid, QC risk

Installation tips (the 5-minute version)

  • Clean h7 shaft, light oil film; slide insert, square the bracket, then torque bolts evenly.
  • Tighten set screws to spec; rotate shaft while greasing until the seal just “breathes.”
  • Recheck after first shift; misalignment is the silent killer.

Bottom line: the 12mm UCFB201-8 Flange bracket Unit bearing isn’t flashy, but it’s honest kit. Specify the seal and grease correctly and it’ll outlast expectations.
