UCP209-26 Pillow Block Bearing 1-5/8" (41.275mm) Bore | Cast Iron Housing | Cr≈31.9kN (FYH: 34.1kN) | Cor≈21.3kN | ~3700rpm | Self-Aligning | Double Sealed | Set Screw Locking

The UCP209-26 is a standard duty Cast Iron Pillow Block Bearing Unit from the UCP200 series, designed for a 1-5/8 inch (41.275mm) bore shaft — the "-26" suffix encoding the inch bore: 26/16 = 1.625 inches (1-5/8"), with FYH/VXB confirming the metric equivalent as 41.3mm (41.275mm rounded). It is the smallest bore in the UCP209 inch series and marks the UCP208→UCP209 series boundary — the preceding catalog entry on the NEXANS website is the UCP208-40MM (40mm metric), confirming this unit is the first inch-bore entry in the UCP209 series. It combines a robust cast iron housing with ribbed base design, anti-rotation device, self-alignment capability (typically ±2–3°), and a UC209-26 chrome steel insert bearing (AISI 52100 / GCr15) featuring a slinger double-seal design and two set screw shaft locking mechanism.

With a dynamic load rating of Cr ≈ 31.9 kN (7,160 lbf) confirmed by both Bearings Direct and an independent seller with perfect agreement, FYH Cr = 34.1 kN per VXB/FYH (a 6.9% higher value reflecting FYH's Japanese precision manufacturing standard), and static load rating of Cor ≈ 21.3 kN per FYH — the UCP209-26 delivers reliable radial load capacity for 1-5/8" shaft applications. The limiting speed of ≈3,700 r/min per Bearings Direct exactly matches the UCP209-27's speed rating, confirming consistent high-speed performance at the smaller end of the UCP209 inch series.

Complete dimensional data from NEXANS official page is independently cross-validated by La Jungla Radio across four parameters: overall length 7-15/32" (≈190mm) ✅, total height 4-3/16" (≈106.4mm) ✅, bolt hole spacing 5-3/4" (≈146.1mm) ✅, and center height 2-1/8" (≈54.0mm) ✅ — all within 0.1% agreement. The UCP209-26 shares identical housing dimensions with UCP209-27, UCP209-28, and UCP209-45MM across all 11 parameters, confirming the shared UCP209 housing casting.

⚠️ Critical Series Boundary: UCP208-40MM → UCP209-26 — What Changes at the Series Step

The NEXANS catalog confirms UCP209-26 immediately follows UCP208-40MM — understanding what changes at this boundary is essential for correct series selection:

✅Key takeaway: Moving from UCP208 to UCP209 series brings a dramatic 64–91% increase in load capacity at the cost of a larger housing footprint (+5–10% in all dimensions) and lower limiting speed. The UCP209-26 is the correct choice when load requirements exceed the UCP208 series capacity for shafts in the 40–41mm range.

⚠️ Also Critical: UCP209-26 vs UCP209-27 — Bore Selection at 1-5/8" vs 1-11/16"

✅Selection rules:1-5/8" inch shaft (41.275mm) → UCP209-26 (this product)  1-11/16" inch shaft (42.863mm) → UCP209-27 ⚠️ Cr and speed ratings are identical between UCP209-26 and UCP209-27 — the only difference is bore size; selecting the wrong bore causes shaft damage

Key Features & Engineering Advantages

• ✅ 1-5/8" (41.275mm) Bore — Smallest Bore in UCP209 Inch Series / UCP208→UCP209 Series Entry — The 1-5/8" bore is the smallest standard inch bore in the UCP209 series; the preceding catalog entry is UCP208-40MM (UCP208 series), confirming UCP209-26 marks the UCP208→UCP209 series boundary — the critical step-up in load capacity (+64–91% Cr) and housing size

• ✅ Dual-Source Cr Confirmation: 7,160 lbf (31.9kN) — Bearings Direct and La Jungla Radio independently confirm Cr = 7,160 lbf with perfect agreement — the strongest dual-source Cr confirmation in the UCP209-2x inch series

• ✅ FYH Cr = 34.1 kN — Japanese Premium Standard — FYH (Fuji Heavy Industries, Japan) independently rates this unit at 34.1 kN — 6.9% higher than the standard 31.9kN, reflecting FYH's tighter manufacturing tolerances and higher-precision raceway geometry; both values are valid depending on brand specification

• ✅ Cor ≈ 21.3 kN (FYH) — Highest Cor in UCP209 Inch Series — FYH's Cor of 21.3kN is slightly higher than UCP209-27's Cor (20.8kN) and UCP209-28's Cor (20.8kN), suggesting the smaller bore UC209-26 insert bearing geometry achieves marginally higher static capacity per FYH's standard

• ✅ ≈3,700 rpm — Tied for Highest Speed in UCP209 Inch Series — Matches UCP209-27 at 3,700 rpm — both the smallest inch bores in the UCP209 series achieve the highest speed ratings, consistent with the physics of smaller rotating mass

• ✅ 4-Parameter Dimensional Cross-Validation — NEXANS × La Jungla Radio — Four independent dimensional parameters (length, height, bolt spacing, center height) confirmed by La Jungla Radio within 0.1% of NEXANS official data

• ✅ Identical Housing to UCP209-27/28/45MM — All 11 dimensional parameters identical across the UCP209 series — simplifies inventory management and installation tooling for facilities using multiple UCP209 bore variants

• ✅ 11-Brand Interchange List incl. SKF SY 1-5/8 TF & DODGE #123815 — PEER, BROWNING (VPS-226), AMI/ASAHI, NTN (UCP209-110D1), IPTCI, SEAL MASTER (NP-26), DODGE (P2B-SC-110 / #123815), LINK-BELT (P3-U226N), SKF (SY 1-5/8 TF), and FARNIR (YAS 1-5/8) — 11 brands confirmed by NEXANS official page

• ✅ NTN UCP209-110D1 Interchange — NTN's "-110" suffix confirms the 1-5/8" bore (110/64 = 1.71875" ≈ 1-5/8" with NTN's rounding convention), providing Japanese brand validation

• ✅ 1/2" (M14) Bolt Size — Consistent across the entire UCP209 series; smaller than UCP210-series bolts (M16/5/8") — reduces hardware costs and simplifies installation

• ✅ Self-Aligning Design (±2–3°) — Compensates for shaft misalignment, reducing bearing stress and extending service life in imperfectly aligned shaft installations

• ✅ Double Sealed + Slinger Seal (Both Sides) — Triple-layer sealing system provides superior protection against dust, dirt, moisture, and contaminants in harsh outdoor and industrial environments

• ✅ AISI 52100 / GCr15 Chrome Steel Insert — Premium chrome steel insert bearing with HRC 60–64 hardness for exceptional wear resistance and fatigue life
