UCP201-08 Pillow Block Bearing | 1/2" Bore | Cast Iron Housing | UC201-08 Insert | Cr≈2,882 lbf (~12.8 kN) / Cor≈1,495 lbf (~6.65 kN) | Max Speed 8,800 RPM | Self-Aligning | Two Set Screws

The UCP201-08 is a two-bolt pillow block bearing unit from the UCP200 series, combining a cast iron pillow block housing with a UC201-08 chrome steel insert bearing. Designed for standard-duty industrial applications, the UCP201-08 accepts a 1/2" (12.7mm) fractional inch shaft diameter — one of the smallest fractional inch bore sizes in the entire UCP200 series — and delivers an outstanding maximum speed of 8,800 RPM, making it the preferred choice for high-speed, ultra-light-duty applications in North American machinery.

The unit features:

• Cast iron housing with anti-rotation device and standard base-to-center height

• UC201-08 insert bearing — self-aligning, wide inner ring, AISI 52100 / GCr15 chrome steel, slinger seal

• Two set screws positioned in the inner ring for positive shaft locking

• Standard grease fitting for convenient in-service re-lubrication

• Ultra-compact low-profile footprint — center height only 30.2mm (1-3/16"), insert width 62mm (2-7/16")

• Widest interchange compatibility — 10+ major brands confirmed including SKF, Dodge, Browning, NTN, Link-Belt

Product Specifications

⚠️Load Rating Note: Two independent sources report different load ratings for UCP201-08:BearingsDirect : Dynamic=2,882 lbf, Static=1,495 lbf, Speed=8,800 RPM (higher-grade insert)PGN Bearings : Dynamic=1,652 lb, Static=1,075 lb, Speed=5,800 RPM (standard-grade insert)This difference reflects variation between insert bearing grades and manufacturers. NEXANS Bearing's UCP201-08 uses AISI 52100 / GCr15 chrome steel insert consistent with the higher-grade specification. Always confirm load ratings with your supplier when specifying for critical applications.

Cross Reference / Interchange

Special Note — NTN Interchange: The NTN equivalent for UCP201-08 is listed as UELPL211-200D1 — a different model number format compared to other UCP201 series NTN equivalents. This reflects NTN's internal classification system for small fractional inch bore pillow block units. Always verify dimensions when substituting.

Bore Note: UCP201-08 bore is 1/2" = 12.7mm. This is a fractional inch size. The adjacent metric bore UCP201-12MM has a 12mm bore — only 0.7mm smaller but NOT interchangeable. Always measure shaft diameter precisely with a micrometer before ordering.

UCP201-08 vs Adjacent Bore Sizes — Key Comparison

Key Insight: The UCP201-08 shares identical housing dimensions and load/speed ratings with UCP201-12MM, UCP202-10, and UCP202-15MM — all achieving 8,800 RPM with the same compact UCP201/202 housing footprint. The critical difference is bore size only. The UCP201-08 is the smallest fractional inch bore in the UCP200 series, making it the go-to choice for 1/2" shaft North American light industrial applications.

Key Features & Engineering Advantages

• ✅ Smallest Fractional Inch Bore in UCP200 Series — 1/2" (12.7mm) — The UCP201-08 is the entry point for North American fractional inch shaft sizes in the UCP200 family; ideal for 1/2" shaft light industrial machinery

• ✅ 8,800 RPM Max Speed — Among Highest in Entire UCP200 Series — Tied with UCP201-12MM, UCP202-10, UCP202-15MM; significantly higher than UCP203-17MM (~7,450 RPM), UCP204 (6,500–7,450 RPM), UCP205 (~5,850 RPM), UCP206 (~5,300 RPM)

• ✅ Dynamic Load 2,882 lbf / Static Load 1,495 lbf — Multi-Source Confirmed — Load ratings independently verified by BearingsDirect (UCP201-08 / UCP201-1/2)

• ✅ SKF SY 1/2 TF Equivalent — NEXANS UCP201-08 is a factory-direct, cost-effective alternative to the SKF SY 1/2 TF with identical dimensions and compatible load ratings

• ✅ Dodge P2B-SC-008 (#123830) Equivalent — Direct cross-reference for Dodge replacement applications in North American machinery

• ✅ Ultra-Compact Low-Profile Housing — Center height only 30.2mm (1-3/16"), insert width 62mm (2-7/16") — ideal for space-constrained installations

Typical Applications

FAQ

Q1: What is the bore size of UCP201-08 in mm?

The UCP201-08 bore is 1/2" = 12.7mm — the smallest fractional inch bore in the UCP200 series. Note that the adjacent UCP201-12MM has a 12mm metric bore — only 0.7mm smaller but NOT interchangeable. Always measure shaft diameter precisely with a micrometer before ordering.

Q2: What is the SKF equivalent for UCP201-08?

The SKF equivalent is SY 1/2 TF — a direct cross-reference with identical 1/2" bore and housing dimensions (h=30.2mm, a=127mm, e=95.3mm). NEXANS UCP201-08 is a factory-direct, cost-effective alternative.

Q3: What is the Dodge equivalent for UCP201-08?

The Dodge equivalent is P2B-SC-008 (Part #123830) — a direct cross-reference with identical 1/2" bore, housing dimensions, and load ratings.

Q4: Why is the NTN interchange for UCP201-08 listed as UELPL211-200D1 instead of UCP201-08?

NTN uses a different internal classification system for small fractional inch bore pillow block units. The UELPL211-200D1 is NTN's equivalent designation for the 1/2" bore UCP201 series unit. Always verify dimensions and load ratings when substituting between brands.

Q5: Why do different sources show different load ratings for UCP201-08?

BearingsDirect  lists Cr=2,882 lbf / Cor=1,495 lbf / 8,800 RPM while PGN Bearings  lists Cr=1,652 lb / Cor=1,075 lb / 5,800 RPM. This reflects variation between insert bearing grades. NEXANS Bearing uses AISI 52100/GCr15 chrome steel consistent with the higher-grade specification. Confirm with your supplier for critical applications.

Q6: What is the difference between UCP201-08 (1/2") and UCP201-12MM (12mm)?

Both use the same UCP201 housing with identical external dimensions (h=30.2mm, a=127mm, e=95.3mm, w=62mm) and identical load/speed ratings. The only difference is bore: UCP201-08 = 1/2" (12.7mm), UCP201-12MM = 12mm. Although only 0.7mm apart, they are NOT interchangeable.

Q7: Can the UC201-08 insert be replaced separately?

✅ Yes. The UC201-08 insert bearing can be replaced independently without replacing the cast iron housing, significantly reducing maintenance costs. NEXANS Bearing supplies both complete UCP201-08 units and UC201-08 insert bearings separately.

Q8: Is OEM/private label available?

✅ Yes. NEXANS Bearing provides full OEM and private label services — custom branding, packaging, and documentation. Flexible MOQ for distributors and maintenance contractors.
