UCP212-38 Pillow Block Bearing 2-3/8" (60.325mm) Bore | Cast Iron Housing | Cr≈47.7–52.4kN | Cor≈33.4–36.2kN | 2800rpm | Self-Aligning | Double Sealed | Set Screw Locking

With a dynamic load rating of Cr ≈ 47.7–52.4 kN (10,718–11,780 lbf) confirmed by PGN Bearings and Timken respectively, static load rating of Cor ≈ 33.4–36.2 kN (7,515–8,138 lbf), and limiting speed of 2,800 r/min, the UCP212-38 delivers reliable radial load capacity for 2-3/8 inch shaft applications across North American agricultural, industrial, and conveyor machinery. At ≈4.90 kg (10.8 lbs) — confirmed by Timken via mrosupply.com — it is notably lighter than the UCP213/UCP214 series, making it ideal for weight-sensitive or space-constrained installations.

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

• ✅ 2-3/8" (60.325mm) Bore — Standard North American Fractional Shaft Size — The 2-3/8" bore is a widely used fractional inch shaft size in North American agricultural, conveyor, and industrial machinery; the "-38" suffix encodes the inch bore: 38/16 = 2.375 inches (2-3/8")

• ✅ Cr≈47.7–52.4kN / Cor≈33.4–36.2kN — Multi-Brand Multi-Source Confirmed — Dynamic load rating confirmed by PGN Bearings at 10,718 lbf (≈47.7kN) and Timken at 11,780 lbf (≈52.4kN); static load rating confirmed by PGN at 7,515 lbf and Timken at 8,138 lbf — both premium global brands providing high data confidence across the range

• ✅ 2,800 r/min Limiting Speed — Confirmed by PGN Bearings — The highest limiting speed in the UCP212–UCP215 range, reflecting the smaller bore and lighter rotating mass — ideal for moderate-to-higher-speed 2-3/8" shaft applications

• ✅ Lightweight ≈4.90 kg (10.8 lbs) — Timken Confirmed — Significantly lighter than UCP213 (≈6.5kg) and UCP214 (≈6.5–7.3kg) series, making UCP212-38 the preferred choice for weight-sensitive or space-constrained installations

• ✅ Identical Housing to UCP212-39 & UCP212-60MM — The UCP212-38 shares the exact same UCP212 housing (241×69.6×138.1mm, h=69.8mm, M16 bolts) as UCP212-39 (2-7/16") and UCP212-60MM (60mm metric) — enabling easy housing stock consolidation for distributors serving multiple shaft size markets

• ✅ M16/5/8" Bolt Size — One size smaller than UCP213/UCP214 (M20/3/4"), consistent with the lighter UCP212 housing design; important for installation planning and bolt stock management

• ✅ Exceptionally Wide Interchange List (11 Brands) — Directly interchangeable with Timken, FYH, PEER, BROWNING VPS-238, AMI/ASAHI, NTN UCP212-206D1, IPTCI, SEAL MASTER NP-38, DODGE P2B-SC-206, LINK-BELT P3-U238N, and FARNIR YAS 2-3/8 — one of the widest interchange lists in the UCP212 series

• ✅ Cast Iron Housing with Anti-Rotation Device — Robust 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

• ✅ 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 UCP212-38's 2-3/8" bore, Cr≈47.7–52.4kN, 2,800rpm limiting speed, double-sealed cast iron housing, self-aligning design, and lightweight ≈4.90kg:

Cross Reference / Interchange

UCP212-38 vs UCP212-39 vs UCP212-60MM — Key Differences

⚠️Critical Selection Note: The UCP212-38 (60.325mm), UCP212-39 (61.9mm), and UCP212-60MM (60mm) all share the exact same UCP212 housing and bolt pattern, but their insert bearings have different bore sizes. Note that UCP212-38 (60.325mm) and UCP212-60MM (60mm) are only 0.325mm apart in bore size — these are absolutely NOT shaft-interchangeable. Always specify the exact model suffix for your shaft standard. The UCP212-38 has the widest interchange list (11 brands) of the three, reflecting its status as the most widely distributed 2-3/8" pillow block unit in North America.

Series Context — UCP212-38 within the UCP200 Pillow Block Series

Key Series Insights:The "-38" suffix encodes the inch bore: 38/16 = 2.375 inches (2-3/8") — a standard North American fractional shaft size  The UCP212-38 shares its exact UCP212 housing with UCP212-36, UCP212-60MM, and UCP212-39 — one housing, four bore options covering both inch and metric shaft standards  Timken and PGN Bearings both confirm the load range independently: Cr=47.7–52.4kN, Cor=33.4–36.2kN — two premium global brands providing reliable data bounds  The 11-brand interchange list — including Timken, FYH, PEER, BROWNING, AMI, NTN, IPTCI, SEAL MASTER, DODGE, LINK-BELT, and FARNIR — is the widest in the UCP212 inch-bore series, confirming UCP212-38 as a globally standardized 2-3/8" pillow block unit  The 2,800 r/min limiting speed is the highest in the UCP212–UCP215 range, confirmed by PGN Bearings — making UCP212-38 the best choice when shaft speed exceeds 2,350–2,450 rpm
