UCP213-40 Pillow Block Bearing 2-1/2" (63.5mm) Bore | Cast Iron Housing | Cr=57.2kN | Cor=40kN | 2350rpm | Self-Aligning | Double Sealed | Set Screw Locking

The UCP213-40 is a standard duty Cast Iron Pillow Block Bearing Unit from the UCP200 series, designed for a 2-1/2 inch (63.5mm) bore shaft — the "-40" suffix encoding the inch bore: 40/16 = 2.500 inches (2-1/2"). It combines a robust cast iron housing with an anti-rotation device, self-alignment capability (typically ±2–3°), and a UC213-40 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 = 57.2 kN (12,859 lbf) per SKF official data and static load rating of Cor = 40 kN (8,992 lbf) — independently confirmed by both SKF (skf.com) and PGN Bearings (pgnbearings.com) with identical Cor values — and a limiting speed of 2,350 r/min, the UCP213-40 delivers reliable radial load capacity for 2-1/2 inch shaft applications across North American agricultural, industrial, and conveyor machinery.

The standard grease fitting (Zerk fitting) allows for in-service relubrication without disassembly, extending service life in demanding environments. The cast iron housing provides excellent rigidity and vibration damping, while the self-aligning insert bearing design compensates for shaft misalignment caused by thermal expansion, structural deflection, or imperfect installation.

Product Specifications

Key Features & Engineering Advantages

• ✅ 2-1/2" (63.5mm) Bore — Standard North American Fractional Shaft Size — The 2-1/2" bore is a widely used fractional inch shaft size in North American agricultural, conveyor, and industrial machinery; the "-40" suffix encodes the inch bore: 40/16 = 2.500 inches (2-1/2")

• ✅ Cr=57.2kN / Cor=40kN — SKF Official + PGN Dual-Source Confirmed — Dynamic load rating confirmed by SKF at 12,859 lbf (≈57.2kN); static load rating of 8,992 lbf (≈40kN) independently confirmed by both SKF and PGN Bearings with identical values, providing the highest data confidence

• ✅ 2,350 r/min Limiting Speed (SKF h6 Shaft Tolerance) — Confirmed by SKF official data; PGN Bearings lists a conservative 2,200 rpm — both values confirm suitability for moderate-speed industrial applications

• ✅ Identical Housing to UCP213-65MM — The UCP213-40 shares the exact same UCP213 housing (265×70×150mm, h=76.2mm, M20 bolts) as the UCP213-65MM, differing only in insert bearing bore (63.5mm inch vs 65mm metric) — enabling easy housing stock consolidation

• ✅ Cast Iron Housing with Anti-Rotation Device — Rigid cast iron housing provides excellent vibration damping and structural integrity; anti-rotation pin prevents insert bearing rotation within housing under shock loads

• ✅ 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 — Triple-layer sealing system provides superior protection against dust, dirt, moisture, and contaminants in harsh outdoor and industrial environments

• ✅ Two Set Screw Locking — Dual set screws in the wide inner ring provide positive shaft locking and prevent axial displacement under heavy loads and vibration

• ✅ Standard Grease Fitting (Zerk) — Allows convenient in-service relubrication without disassembly, critical for extended maintenance intervals in remote or hard-to-access installations

• ✅ Wide Inner Ring (Bi=65.1mm / 2.563 in) — Extended inner ring width provides greater shaft contact area, improving set screw grip and reducing shaft fretting

• ✅ Wide Interchange List (8+ Brands) — Directly interchangeable with SKF UCP213-40, DODGE P2B-SC-208, LINK-BELT P3-U240N, AMI/ASAHI UCP213-40, PEER UCP213-40, NTN UCP213-208D1, BROWNING VPS-240, FARNIR YAS 2-1/2, and Seal Master NP-40

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

Typical Applications

Based on the UCP213-40's 2-1/2" bore, Cr=57.2kN, 2,350rpm limiting speed, double-sealed cast iron housing, and self-aligning design:

Cross Reference / Interchange

UCP213-40 vs UCP213-65MM vs UCP212-60MM — Key Differences

⚠️ Critical Selection Note: The UCP213-40 (63.5mm) and UCP213-65MM (65mm) share the exact same UCP213 housing and bolt pattern, but their insert bearings have different bore sizes (63.5mm vs 65mm — a difference of 1.5mm). These are NOT shaft-interchangeable — always specify "-40" for 2-1/2" inch shafts and "-65MM" for 65mm metric shafts. Both use the same M20/3/4" bolt size and identical housing footprint (265×70×150mm).

Series Context — UCP213-40 within the UCP200 Pillow Block Series

Key Series Insights:The "-40" suffix encodes the inch bore: 40/16 = 2.500 inches (2-1/2") — a standard North American fractional shaft size widely used in agricultural and industrial machinery  The UCP213-40 shares its exact UCP213 housing with UCP213-65MM, making it easy to stock one housing type while offering two bore insert bearings for inch (63.5mm) and metric (65mm) shaft standards Cor=40kN confirmed by two independent sources (SKF at 8,992 lbf and PGN Bearings at 8,992 lbf — identical values), providing the highest static load data confidence in this series  The 2,350 r/min limiting speed (SKF h6) is consistent with the mid-heavy UCP213 series design, with PGN Bearings listing a conservative 2,200 rpm — both confirm suitability for moderate-speed applications  The 8+ brand interchange list including SKF UCP213-40, DODGE P2B-SC-208, and LINK-BELT P3-U240N confirms UCP213-40 as a globally standardized 2-1/2" pillow block unit widely stocked across North American industrial distributors
