UCFA206-19 Take Up Housing Bearing Unit Pillow Block, Sealed


Hands-on Notes: UCFA Take-Up Units That Actually Hold Up

If you’ve wrestled with belt tracking on conveyors (who hasn’t), the UCFA206-19 Take Up Housing Bearing Unit Pillow Block Bearing is one of those pragmatic choices people keep circling back to. It’s a UC insert with set-screw locking in a cast-iron take-up housing, slotted for belt tension adjustments. Nothing flashy—just a sturdy, greaseable workhorse. In fact, many customers say the payoff is fewer mid-shift stops. I’ll take that any day.

Quick Specs (real-world values may vary)

Shaft diameter1-3/16 in (≈30.16 mm)
InsertUC206-19, 2×M6 grub/set screws @ 120°
HousingUCFA take-up, cast iron (HT200 / ASTM A48 Class 30)
SealsContact rubber 2RS + flingers; triple-lip option
Dynamic load rating C≈19.5 kN
Static load rating C₀≈11.3 kN
Misalignment toleranceUp to ±2°
Grease fillLithium EP2 (NLGI 2), ≈25–35%
Operating temperature-20 to 100 °C (peaks ≈120 °C)
Speed guidelineAround 3,000 rpm, load/grease dependent
MountingElongated slots for take-up frames; re-lube fitting
StandardsISO 492 (tolerances), ISO 281 (life), RoHS/REACH

How it’s made (and why it lasts)

Rings use GCr15 (52100) bearing steel, hardened to HRC 60–64; the housing is grey cast iron. Process flow: CNC turning → heat treatment → grinding → seal and flinger fitment → lithium EP2 grease → torque-checked set screws → 100% spin/noise check (ISO 15242 method). Coating passes ≈72 h neutral salt spray (ASTM B117) on painted surfaces. Typical L10 life, to be honest, depends on load. At 5 kN radial and 600 rpm, you’re looking at in the 40,000–60,000 h bracket per ISO 281—assuming decent alignment and no gritty surprises.

Where it fits best

  • Conveyor take-up frames in quarries, recycling, aggregates
  • Packaging lines and light material handling (adjustable tension)
  • Wood processing, agriculture, small HVAC belt drives

Mini case #1: A limestone quarry swapped in UCFA206-19 Take Up Housing Bearing Unit Pillow Block Bearing on a troublesome take-up. Reported a ≈30% drop in belt-tracking stops over a quarter—mostly because the slotted housing let them dial tension properly. Mini case #2: A canning plant used a stainless-insert variant with triple-lip seals; daily washdowns, zero water ingress noted at 12 months (moderate speed). Anecdotal, yes, but consistent with what we hear.

Vendor snapshot (typical market comparison)

Vendor Material/Seal QC & Tests Lead Time Price Level
BTZ Bearing (factory) HT200 + 2RS; EP2 grease ≈30% ISO 9001; salt spray ≈72 h; vibration V1 ≈10–20 days Mid
Generic Import A Cast iron + basic seals Spot checks; tests vary Around 30 days Low
Big-brand X Premium seals; high-spec grease Full ISO/ABMA audits; extended testing Stock/fast High

Customization

  • Stainless insert or housing; food-grade grease
  • Eccentric locking instead of set screws
  • Triple-lip seals, shrouds, or closed-end caps
  • C3 clearance for higher temps; special coatings

Customer note: “Installed two UCFA206-19 Take Up Housing Bearing Unit Pillow Block Bearing on our feed conveyor—quiet, no loosening after the first week. Grease nipple access is actually convenient.” It seems that simple things—like zerk placement—still matter.

Origin: No. 3, Area B, Bearing Industry Mass Entrepreneurship Park, Beihuan Road, Linxi County, Xingtai City, Hebei Province.

Trend watch

We’re seeing more sealed-for-life requests, energy-efficient belt runs (lower friction seals), and faster lead times. Honestly, the units that balance affordability with proper sealing and decent grease—like the UCFA206-19 Take Up Housing Bearing Unit Pillow Block Bearing—are winning the procurement meetings.
