UCFC212-38 Round Flange Housing 4 Bolt Ball Bearing 2-3/8 in


Field Notes on the UCFC212-38: A 4-Bolt Round Flange That Punches Above Its Weight

If you work around conveyors, augers, or fans, you’ve probably seen a round flange unit earn its keep. The UCFC212-38 Round Flange Housing 4 Bolt Ball Bearing is one of those parts that quietly prevents chaos. I’ve seen it in packaging lines and grain elevators—doing that unglamorous job of keeping a shaft stable, aligned, and blissfully boring. That’s the goal, honestly.

UCFC212-38 Round Flange Housing 4 Bolt Ball Bearing 2-3/8 in

Origin story matters for some buyers: this unit ships from No. 3, Area B, Bearing Industry Mass Entrepreneurship Park, Beihuan Road, Linxi County, Xingtai City, Hebei Province. Many customers say the consistency is what keeps them re-ordering. I guess that checks out—consistency is the whole point in bearings.

Where it fits (literally and figuratively)

Typical use cases include belt conveyors, agricultural augers, HVAC fan assemblies, food-pack end-of-line rollers (non-washdown zones), light mining screens, and general factory automation. I’ve also seen teams use UCFC212-38 Round Flange Housing 4 Bolt Ball Bearing units as retrofit solutions when pillow blocks were eating misalignment for breakfast.

Materials, build, and test flow

Materials: high-strength cast iron housing; chrome steel bearing rings and balls; nitrile or similar seal; plated slinger. Methods: CNC-machined seating faces, ground raceways, phosphate/anti-corrosion treatment where specified. Testing: dimensional per ISO 492, grease quality cross-checked against ASTM D4170 concepts, life calculations following ISO 281, runout checks, and 100% spin/feel inspection. Service life? In clean, aligned systems, I’ve seen UCFC212-38 Round Flange Housing 4 Bolt Ball Bearing units run several seasons with only routine greasing.

Why teams pick this unit

  • Round flange centers easily on ducts, fan housings, and sheet-metal frames.
  • Set-screw locking is simple; maintenance crews already know it.
  • Greaseable and service-friendly; parts availability is solid.
  • Balanced spec: not overbuilt, not flimsy—just right for conveyors and fans.

Vendor snapshot (what buyers actually compare)

VendorLead Time ≈CertificationsNotes
BTZ Bearing (origin manufacturer)Stock–2 wksISO 9001 (typical), RoHS/REACH on requestDirect support; customization options
Global Brand Distributor1–3 wksGlobal QA frameworksHigher price; broad network
Local Industrial SupplierSame-day–1 wkVariesGreat for emergencies; limited customization

Note: lead times and certifications vary by lot and region.

Customization and compliance

Options often include stainless inserts, triple-lip seals, food-grade grease, and coated housings. Compliance documents (ISO 9001, material RoHS/REACH statements) are typically available. For regulated sites, request PPAP-lite or CoC upfront—saves time later.

Mini case: packaging line, Midwest

A snack plant swapped failing pillow blocks on a diverter conveyor for UCFC212-38 Round Flange Housing 4 Bolt Ball Bearing units. After alignment and a sane grease schedule, downtime dropped noticeably—operators said the noise fell off too. Not a miracle, just better fit and sealing for the application.

Installation tips I keep repeating

  • Shaft tolerance near h7; clean, burr-free surface.
  • Cross-tighten the four bolts; do not “pull” the housing into position.
  • Set-screw torque to spec; avoid over-tightening on soft shafts.
  • Grease sparingly; over-greasing can pop seals.
