UCFA209-26 Take Up Housing Bearing Unit Pillow Block Bearing


Field Notes on the UCFA209-26 Take Up Housing Bearing Unit Pillow Block Bearing

I’ve seen take-up units live very easy lives on tidy conveyors—and very rough ones in aggregate yards where dust finds everything. The UCFA209-26 Take Up Housing Bearing Unit Pillow Block Bearing is built for both, which, to be honest, is why maintenance teams keep asking about it.

What it is and why it’s trending

UCFA-style housings are take-up units with slotted feet—meaning you can tension a belt or chain without moving the whole frame. This UCFA uses a cast iron housing and a UC-series radial insert ball bearing with grub screws (set screws) on the inner ring. Industry trend? More plants are moving to pre-assembled units like this to shorten planned downtime and standardize spares across lines. It seems mundane, but faster swaps equal real money saved.

Typical applications

  • Bulk-handling conveyors in grain, cement, and recycling
  • Take-up stations on package sorters and parcel hubs
  • Light-duty mining/aggregate handling (dry environments)
  • General plant drives where belt tensioning is routine

Key specs (real-world values may vary)

ParameterValue
Shaft size1-5/8 in (≈41.28 mm), “-26” inch bore
HousingCast iron (HT200/gray iron), UCFA take-up style
InsertUC209-series, steel GCr15 (AISI 52100), set-screw locking
SealingDouble-lip contact seals + flinger
GreaseEP2 lithium soap; -20 to 120 °C typical
Dynamic load rating (C)≈ 31–34 kN (UC209 class)
Static load rating (C0)≈ 19–20 kN
Grease speed limit≈ 3,000–3,600 rpm
Standards refsISO 281 (life), ISO 76 (static), ISO 15243 (failure modes)

In practice, many customers say the UCFA209-26 Take Up Housing Bearing Unit Pillow Block Bearing runs cooler than older units, especially when aligned well and not over-greased (common pitfall!).

Manufacturing and testing flow

Materials are selected (GCr15 rings, grade iron housing), then: forging → turning → heat treatment → grinding (P6/P0 accuracy depending on spec) → seal assembly → grease fill (ASTM D4950 GC-LB class equivalents) → torque/rotation test → noise/vibration check → dimensional audit → packing. Life estimates follow ISO 281 L10 methodology; failure analysis aligns with ISO 15243. Typical service life, frankly, depends on alignment, load spectrum, and contamination—get the seals right and you’re halfway there.

Vendor snapshot and customization

Origin: No. 3, Area B, Bearing Industry Mass Entrepreneurship Park, Beihuan Road, Linxi County, Xingtai City, Hebei Province. Options often include stainless inserts, triple-lip seals, solid lubrication, and food-grade grease—although for heavy washdown you might prefer thermoplastic or stainless housings.

Real-world case and feedback

Case: a grain elevator retrofitted two take-up stations with the UCFA209-26 Take Up Housing Bearing Unit Pillow Block Bearing. After six months: no relube failures, temperature dropped ≈6–8 °C at steady load, and belt tracking stabilized. Maintenance lead told me, “Surprisingly boring—in a good way.”

Quick usage tips

  • Set-screw torque to spec; re-check after 24 hours.
  • Grease moderately; purge until slight seal lift, then stop.
  • Keep take-up travel clean; contamination shortens life fast.
  • For corrosive washdown, consider stainless or polymer housings.
