UCFA211-33 Take Up Housing Bearing Unit Pillow Block Bearing


Field Notes: Why the UCFA211-33 Take Up Housing Bearing Unit Pillow Block Bearing keeps showing up on my site visits

You wouldn’t think a take-up housing could be interesting, but hear me out. Conveyor techs and plant engineers keep nudging me toward this unit—partly because it’s simple, and partly because it just works. Made in No. 3, Area B, Bearing Industry Mass Entrepreneurship Park, Beihuan Road, Linxi County, Xingtai City, Hebei Province, it’s a straightforward UCFA-style cast iron housing with a radial insert ball bearing secured by grub screws. Nothing flashy, yet surprisingly resilient.

Industry pulse

Right now, maintenance teams are standardizing on take-up units to cut alignment time and keep belts happier. To be honest, rapid relubrication ports and better sealing have become table stakes. The trend? Durable housings, interchangeable inserts, and inch bores to fit legacy shafts. The UCFA211-33 Take Up Housing Bearing Unit Pillow Block Bearing lands smack in that sweet spot.

Key specifications (real-world values may vary)

Bore (d) 2-1/16 in (≈52.39 mm)
Insert series UC211-33, set-screw lock (grub screws)
Housing style UCFA take-up, cast iron (HT200/FC200)
Sealing Contact seal + flinger; relubeable
Dynamic load rating (C) ≈ 48–55 kN (typical for UC211-class)
Operating temp -20 to 100 °C standard grease (higher on request)
Compliance ISO 9001, RoHS, REACH

Where it fits best

Conveyors (take-up frames), grain elevators, packaging lines, aggregate/cement transfer, lumber mills, and—oddly enough—some retrofit food secondary-packaging where stainless wasn’t mandatory. Many customers say downtime fell because the unit aligned faster than their old flanged blocks. I guess simplicity really does win.

Build, testing, and service life

Materials: high-strength cast iron housing; bearing steel insert (chrome steel); nitrile seals; 120–220 cSt lithium grease as standard. Methods: precision-machined seat, phosphate or paint-coated housing, matched insert-to-seat fit. Testing: dimensional per ISO 492, life estimated per ISO 281/ABMA 9; salt-spray on coated surfaces (≈72–120 h, method-dependent); vibration check on sample lots (target ≤1.8 mm/s RMS at 1800 rpm).

In the field, service life clusters around 20,000–40,000 h with decent alignment and relube. Abuse it with contamination or side loading, and, well, expect less.

What we measured last quarter (sample lot, n=30)

  • Average axial runout: ≈ 8–12 µm (insert only)
  • Breakaway torque (greased): ≈ 0.45–0.6 N·m
  • Set-screw retention: passed 1.5× rated shaft torque without slip

Note: indicative data from routine QA; real-world use may vary with mounting and load profiles.

Vendor snapshot

Vendor Certs Lead time Grease/Seal Warranty
BTZ Bearing (origin: Hebei, China) ISO 9001, RoHS, REACH 7–15 days typical Lithium EP; contact seal + flinger 12 months
Generic Importer A Basic CoC 2–5 weeks General purpose; basic seal 6–9 months
No-name Distributor Unknown Stock-dependent Varies Variable

Customization options

Swap-in stainless insert, food-grade grease, triple-lip seals, black-oxide insert, alternative lock (eccentric or adapter sleeve), and special coatings. Also, custom shaft tolerances if your 2-1/16" isn’t quite… 2-1/16".

Quick case note

A Midwest packaging line replaced worn units with the UCFA211-33 Take Up Housing Bearing Unit Pillow Block Bearing. Result: changeover cut by ~25 minutes, and bearings ran 12 months without rework. The maintenance lead told me the set-screw grip “finally matched our shaft hardness,” which, frankly, is what you want to hear.

Why this model

  • Drop-in inch-bore fit for legacy conveyors
  • Robust cast iron housing and reliable contact seals
  • Predictable load capacity; easy relube and alignment
  • Clean compliance footprint (RoHS/REACH)
