UCP215-47 Pillow Block Bearing 2-15/16" (74.6mm) Bore | Cast Iron Housing | Cr≈67.4kN | 2300rpm | Self-Aligning | Double Sealed | Set Screw Locking

The UCP215-47 is a standard duty Cast Iron Pillow Block Bearing Unit from the UCP200 series, designed for a 2-15/16 inch (74.6mm) bore shaft. It combines a robust cast iron housing with an anti-rotation device, self-alignment capability (typically ±2–3°), and a UC215-47 chrome steel insert bearing featuring a slinger double-seal design and two set screw shaft locking mechanism.

With a dynamic load rating of Cr = 62.1–67.4 kN (13,956–15,152 lbf) — confirmed across bearingsdirect.com, vxb.com, and PTI/mrosupply.com — the UCP215-47 delivers reliable radial load capacity for heavy-duty 2-15/16 inch shaft applications. Its limiting speed of 2,300 rpm makes it well-suited for moderate-speed industrial and agricultural 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. At ≈17.4–19.1 lbs (7.9–8.7 kg), the UCP215-47 is a robust yet manageable unit for field installation.

Product Specifications

Key Features & Engineering Advantages

• ✅ 2-15/16" (74.6mm) Bore — Most Common North American Fractional Shaft Size — The 2-15/16" bore is one of the most widely used fractional inch shaft sizes in North American agricultural, conveyor, and industrial machinery; the "-47" suffix encodes 47/16 = 2.9375 inches

• ✅ Cr=62.1–67.4kN (Multi-Source Confirmed) — Load capacity confirmed across bearingsdirect.com, vxb.com, and PTI/mrosupply.com, ensuring reliable performance in heavy radial load applications

• ✅ 2,300 rpm Limiting Speed — Consistent with UCP215-48 (3") performance, making the UCP215-47 well-suited for moderate-to-higher-speed 2-15/16" shaft applications in agricultural and industrial machinery

• ✅ 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=77.8mm / 3.063 in) — Extended inner ring width provides greater shaft contact area, improving set screw grip and reducing shaft fretting

• ✅ Exceptionally Wide Interchange List (8+ Brands) — Directly interchangeable with DODGE, LINK-BELT, AMI/ASAHI, PEER, NTN, BROWNING, FARNIR, and Seal Master — ensuring easy global sourcing and replacement

• ✅ Standard M20 / 3/4" Bolt Size — Standard bolt pattern ensures direct drop-in replacement for any existing UCP215-47 installation from any brand

• ✅ GCr15 / 52100 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 UCP215-47's 2-15/16" bore, Cr≈62.1–67.4kN, 2,300rpm limiting speed, double-sealed cast iron housing, and self-aligning design:

Cross Reference / Interchange

UCP215-47 vs UCP215-48 vs UCP215-75MM — Key Differences

⚠️ Critical Note: The UCP215-47, UCP215-48, and UCP215-75MM all share the exact same housing and bolt pattern, but their insert bearings have different bore sizes (74.6mm / 76.2mm / 75.0mm). These are NOT shaft-interchangeable — always specify the correct suffix for your shaft diameter. The 2-15/16" (74.6mm) bore of the UCP215-47 is the smallest of the three, making it the preferred choice for 2-15/16" fractional inch shafts common in North American agricultural equipment.

Series Context — UCP215-47 within the UCP200 Pillow Block Series

Key Series Insights:The "-47" suffix encodes the inch bore: 47/16 = 2.9375 inches (2-15/16") — one of the most common fractional shaft sizes in North American agricultural and industrial equipmentThe UCP215-47 shares its exact housing dimensions with UCP215-48 and UCP215-75MM, making it easy to stock one housing type while offering multiple bore insert bearingsIts 2,300 rpm limiting speed matches the UCP215-48, confirming consistent performance design across the UCP215 inch-bore familyThe 8+ brand interchange list confirms UCP215-47 as one of the most universally standardized 2-15/16" pillow block units globally, with specific DODGE (P2B-SC-215) and LINK-BELT (P3-U247N) equivalents widely used in North American industry
