UCP210-32 Pillow Block Bearing 2" (50.8mm) Bore | Cast Iron Housing | Cr≈35.1kN | Cor≈23.7kN | 3300–3400rpm | Self-Aligning | Double Sealed | Set Screw Locking

The UCP210-32 is a standard duty Cast Iron Pillow Block Bearing Unit from the UCP200 series, designed for a 2 inch (50.8mm) bore shaft — the "-32" suffix encoding the inch bore: 32/16 = 2.000 inches (2"). It is the inch-bore counterpart to the UCP210-50MM (50mm metric), sharing the same compact UCP210 housing but serving 2" inch shafts instead of 50mm metric shafts. It combines a robust cast iron housing with ribbed base design, anti-rotation device, self-alignment capability (typically ±2–3°), and a UC210-32 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 ≈ 34.9–35.1 kN (7,837–7,891 lbf) confirmed across three independent sources — PGN Bearings (7,891 lbf), Bearings Direct (7,866 lbf), and USA Roller Chain (7,837 lbf) — with a maximum three-source variance of only 0.7%, this represents the highest cross-source Cr agreement of any UCP210 inch-bore variant documented. Static load rating Cor ≈ 23.2–23.7 kN (5,216–5,330 lbf) and limiting speed of 3,300–3,400 r/min are confirmed by PGN (3,300 RPM) and Bearings Direct (3,400 RPM) respectively.

At ≈2.59 kg (5.7 lbs) confirmed by USA Roller Chain — consistent with the UCP210-50MM (≈2.6kg) — the UCP210-32 is significantly lighter and more compact than the UCP211-32 (3.54–3.82kg, 219mm length), making it the preferred choice when weight and space constraints are critical for 2" shaft applications. The bolt size is 3/8 in per AMI Bearings official catalog — smaller than the 5/8" (M16) used on the UCP211-32.

⚠️ Critical: UCP210-32 vs UCP210-50MM vs UCP211-32 — Selection Guide

These three units serve nearly identical shaft sizes but are completely different, non-interchangeable products:

✅Selection rules:2" inch shaft + UCP210 housing → UCP210-32 (this product)  50mm metric shaft + UCP210 housing → UCP210-50MM 2" inch shaft + higher load capacity needed → UCP211-32 (Cr≈43.4kN, heavier, larger housing)

Key Features & Engineering Advantages

• ✅ 2" (50.8mm) Bore — Standard North American Fractional Shaft Size in Compact UCP210 Housing — The 2" bore is one of the most universally used shaft sizes in North American industrial and agricultural equipment; the UCP210-32 delivers this bore in the more compact, lighter UCP210 housing vs the UCP211-32

• ✅ Three-Source Cr Agreement < 0.7% — PGN (7,891 lbf), Bearings Direct (7,866 lbf), and USA Roller Chain (7,837 lbf) — maximum variance of only 0.7% across three independent sources — the highest cross-source Cr agreement documented for any UCP210 inch-bore variant

• ✅ 3,300–3,400 r/min — Higher Speed than UCP211-32 — Confirmed by PGN (3,300 RPM) and Bearings Direct (3,400 RPM); the UCP210-32 offers higher limiting speed than the UCP211-32 (3,000–3,100 rpm) for the same 2" bore — ideal for higher-speed, moderate-load applications

• ✅ Lighter & More Compact than UCP211-32 — At ≈2.59 kg (5.7 lbs) and ≈206.5mm length, the UCP210-32 is ≈30% lighter and 12.5mm shorter than the UCP211-32 (3.54–3.82kg, 219mm) — significant advantage for weight-sensitive or space-constrained installations

• ✅ 3/8" Bolt Size — Confirmed by AMI Bearings Official Catalog — Smaller 3/8" mounting bolts vs 5/8" on UCP211-32; reduces hardware costs and simplifies installation in lighter-duty mounting structures

• ✅ Lower Center Height (2-1/4" vs 2-1/2") — H=57.15mm (2-1/4") vs UCP211-32's 63.5mm (2-1/2") — the UCP210-32 sits 6.35mm closer to the mounting surface, reducing moment arm and vibration in high-speed applications

• ✅ Inch-Bore Counterpart to UCP210-50MM — Shares the same UCP210 housing dimensions as the UCP210-50MM (50mm metric) but serves 2" inch shafts; housing bolt pattern is identical, enabling easy conversion between metric and inch shaft configurations without changing the housing

• ✅ Wide Interchange List — 10+ Brands — Directly interchangeable with PGN UCP210-32, AMI UCP210-32, PEER UCP210-32, BROWNING VPS-232, NTN UCP210-200D1, IPTCI UCP210-32, SEAL MASTER NP-32, DODGE P2B-SC-200, LINK-BELT P3-U232N, and FARNIR YAS-2

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

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

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

Series Context — UCP210-32 within the UCP200 Pillow Block Series

Key Insights — UCP210-32 vs UCP211-32 (same 2" bore, different housing):Choose UCP210-32 when: higher speed (3,300–3,400 rpm) is needed, weight/space savings matter (≈30% lighter, 12.5mm shorter), and load requirements are moderate (Cr≈35kN sufficient)  Choose UCP211-32 when: higher load capacity is needed (Cr≈43.4kN — 24% higher), existing mounting uses 5/8" bolt pattern, or replacement of UCP211-series units is required  Housing bolt patterns are NOT interchangeable — UCP210 (159mm bolt spacing, 3/8" bolts) vs UCP211 (170.7mm bolt spacing, 5/8" bolts) — verify existing mounting before substituting
