UCP211-35 Pillow Block Bearing 2-3/16" (55.563mm) Bore | Cast Iron Housing | Cr≈43.4kN | Cor≈29.4kN | 3100rpm | Self-Aligning | Double Sealed | Set Screw Locking

The UCP211-35 is a standard duty Cast Iron Pillow Block Bearing Unit from the UCP200 series, designed for a 2-3/16 inch (55.563mm) bore shaft — the "-35" suffix encoding the inch bore: 35/16 = 2.1875 inches (2-3/16"). It combines a robust cast iron housing with an anti-rotation device, self-alignment capability (typically ±2–3°), and a UC211-35 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 ≈ 43.4 kN (43,400 N / 9,755 lbf) confirmed by VXB and cross-validated against same-housing UCP211-55MM data from Bearings Direct (43.3kN — difference < 0.3%), static load rating of Cor ≈ 29.4 kN (29,400 N / 6,610 lbf), and limiting speed of approximately 3,100 r/min, the UCP211-35 delivers reliable radial load capacity for 2-3/16 inch shaft applications across North American agricultural, industrial, and conveyor machinery.

At ≈3.31–3.80 kg (7.3–8.4 lbs) — confirmed by FYH/Rainbow Precision (7.3 lbs / 3.31kg) and cross-validated against same-housing UCP211-55MM PTI data (8.6 lbs / 3.90kg) — the UCP211-35 is significantly more compact and lighter than the UCP212 series (≈4.80–4.90kg, 241mm length), with a higher limiting speed (3,100 vs 2,800 rpm). This makes it the preferred choice for 2-3/16" inch shafts where installation space, weight, or shaft speed are critical design factors.

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

• ✅ 2-3/16" (55.563mm) Bore — Standard North American Fractional Shaft Size — The 2-3/16" bore is a widely used fractional inch shaft size in North American agricultural, conveyor, and industrial machinery; the "-35" suffix encodes the inch bore: 35/16 = 2.1875 inches (2-3/16")

• ✅ Cr≈43.4kN / Cor≈29.4kN — Dual Cross-Validated — Dynamic load rating confirmed by VXB (43,400 N / 43.4kN), and independently cross-validated against same-housing UCP211-55MM data from Bearings Direct (43.3kN) — difference < 0.3%, providing the highest cross-validation confidence in this series

• ✅ ≈3,100 r/min Limiting Speed — Highest in UCP211–UCP215 Range — Consistent with same-housing UCP211-55MM confirmed value (Bearings Direct); the UCP211-35's 3,100 rpm limiting speed exceeds UCP212 (2,800 rpm), UCP213 (2,350 rpm), UCP214 (2,450 rpm), and UCP215 (2,300 rpm) — making it the best choice when shaft speed is the primary design constraint

• ✅ Lightweight ≈3.31–3.80 kg (7.3–8.4 lbs) — FYH Confirmed — Confirmed by FYH/Rainbow Precision (7.3 lbs / 3.31kg); significantly lighter than UCP212 (≈4.80–4.90kg) and UCP213 (≈6.5kg) series — ideal for weight-sensitive or space-constrained installations

• ✅ Identical Housing to UCP211-55MM — The UCP211-35 shares the exact same UCP211 housing (219×60.3×124.6mm, h=63.5mm, M16 bolts) as UCP211-55MM (55mm metric bore), differing only in insert bearing bore (55.563mm inch vs 55mm metric — a difference of only 0.563mm); enables easy housing stock consolidation for distributors serving both inch and metric shaft markets

• ✅ Widest Interchange List in UCP211 Series — 11+ Brands including SKF, FARNIR & DODGE Part# — Directly interchangeable with SKF SY 2-3/16 TF, FARNIR SY 2-3/16 TF, PEER UCP211-35, BROWNING VPS-235, AMI/ASAHI UCP211-35, NTN UCP211-203D1, IPTCI UCP211-35, SEAL MASTER NP-35, DODGE P2B-SC-203 (Part# 123820), LINK-BELT P3-U235N, NAP211-35, ENLP211-35SJ — the DODGE part number (#123820) is explicitly listed, enabling direct OEM replacement

• ✅ SKF & FARNIR Both Listed — Dual Premium Brand Interchange — The UCP211-35 is one of the few UCP200 series models with both SKF (SY 2-3/16 TF) and FARNIR (SY 2-3/16 TF) in its interchange list — both using the identical part number, confirming the highest level of global standardization and quality benchmark

• ✅ M16/5/8" Bolt Size — Same as UCP212 — Despite being a smaller housing series, the UCP211-35 uses the same M16/5/8" bolt size as UCP212, simplifying bolt stock management for facilities running both 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=55.6mm / 2.189 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 UCP211-35's 2-3/16" bore, Cr≈43.4kN, ≈3,100rpm limiting speed, double-sealed cast iron housing, self-aligning design, and lightweight ≈3.31–3.80kg:

Cross Reference / Interchange

UCP211-35 vs UCP211-55MM vs UCP212-36 — Key Differences

⚠️Critical Selection Note:UCP211-35 (55.563mm) vs UCP211-55MM (55mm): These two models share the exact same UCP211 housing but differ by only 0.563mm in bore — they are absolutely NOT shaft-interchangeable. Always specify "-35" for 2-3/16" inch shafts and "-55MM" for 55mm metric shafts. This is one of the closest bore-size pairs in the entire UCP200 series.UCP211-35 vs UCP212-36: Despite only a 1.587mm bore difference (55.563mm vs 57.15mm), these use completely different housings — UCP211 (219mm, 124.6mm wide, 125mm tall) vs UCP212 (241mm, 138.1mm wide, 138mm tall). The UCP211-35 is lighter, more compact, and faster but has lower load capacity (43.4 vs 52.4 kN).
