Product Description
The UCP214-43 is a standard duty Cast Iron Pillow Block Bearing Unit from the UCP200 series, designed for a 2-11/16 inch (68.263mm) bore shaft. It combines a robust cast iron housing with an anti-rotation device, self-alignment capability (typically ±2–3°), and a UC214-43 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 ≈ 62.2–62.3 kN (13,981–14,000 lbf) and static load rating of Cor ≈ 43.9–44.0 kN (9,869–9,900 lbf) — confirmed independently by TURNER (offroadbelts.com) and AMI Bearings (motion.com) — the UCP214-43 delivers reliable radial load capacity for 2-11/16 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. At ≈14.3–16.1 lbs (6.5–7.3 kg), the UCP214-43 is a robust yet manageable unit for field installation.

✅ 2-11/16" (68.263mm) Bore — Standard North American Fractional Shaft Size — The 2-11/16" bore is a widely used fractional inch shaft size in North American agricultural, conveyor, and industrial machinery; the "-43" suffix encodes 43/16 = 2.6875 inches (2-11/16")
✅ Cr≈62.2–62.3kN / Cor≈43.9–44.0kN (Multi-Source Confirmed) — Load capacity independently confirmed by TURNER (offroadbelts.com) at 13,981 lbf and AMI Bearings (motion.com) at 14,000 lbf — two separate brand sources with near-identical values, ensuring high data reliability
✅ ≈2,450 rpm Limiting Speed — Consistent with UCP214-44 performance in the same UCP214 housing family, making the UCP214-43 well-suited for moderate-to-higher-speed 2-11/16" shaft applications
✅ Compact UCP214 Housing — The UCP214 housing (266mm length, 156.4mm width, 79.4mm center height) is more compact than the UCP215 series, offering a space-saving solution for 2-11/16" shaft installations
✅ 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=74.6mm / 2.937 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 P2B-SC-211, LINK-BELT P3-U243N, AMI/ASAHI UCP214-43, PEER UCP214-43, NTN UCP212-211D1, BROWNING VPS-243, FARNIR YAS 2-11/16, and Seal Master NP-43
✅ AISI 52100 / GCr15 Chrome Steel Insert — Premium chrome steel insert bearing with HRC 60–64 hardness for exceptional wear resistance and fatigue life
Based on the UCP214-43's 2-11/16" bore, Cr≈62.2kN, ≈2,450rpm limiting speed, double-sealed cast iron housing, and self-aligning design:

⚠️ Critical Selection Note: The UCP214-43 (68.263mm) and UCP214-44 (69.85mm) share the exact same UCP214 housing and bolt pattern, but their insert bearings have different bore sizes (68.263mm vs 69.85mm — a difference of 1.587mm). These are NOT shaft-interchangeable — always specify "-43" for 2-11/16" inch shafts and "-44" for 2-3/4" inch shafts. Both use the same M20/3/4" bolt size and identical housing footprint.
