Product Description
The UCP207-35MM is a two-bolt pillow block bearing unit from the UCP200 series, combining a cast iron pillow block housing with a UC207-35MM chrome steel insert bearing. Designed for standard-duty industrial applications, the UCP207-35MM accepts a 35mm shaft diameter and provides a reliable, economical housed bearing solution across a wide range of industries.
The unit features:
Cast iron housing with anti-rotation device and standard base-to-center height
UC207-35MM insert bearing — self-aligning, wide inner ring, chrome steel SAE-52100 / GCr15, slinger seal
Two set screws positioned in the inner ring for positive shaft locking
Standard grease fitting for in-service re-lubrication

✅ Cr=25.5kN / Cor=15.3kN — SKF + Multi-Source Confirmed — Load ratings cross-verified by SKF official data, USARollerChain, and BearingsDirect — consistent across all independent sources
✅ Max Speed 4,300 RPM — Higher limiting speed than UCP208 series, suitable for moderate-to-higher speed applications including fans, pumps, and light conveyor drives
✅ Self-Aligning Design — Accommodates shaft misalignment up to ±2°, reducing installation stress and extending service life in real-world mounting conditions
✅ Cast Iron Housing with Anti-Rotation Device — Prevents insert bearing from rotating within the housing under shock loads or vibration
✅ Two Set Screw Locking — Dual set screws in the wide inner ring provide positive, reliable shaft attachment without requiring keyways
✅ Slinger Seal — Effective contamination exclusion for dusty, wet, or moderately contaminated environments including agriculture, conveyor, and HVAC applications
✅ Chrome Steel SAE-52100 / GCr15 Insert — Industry-standard bearing steel for maximum fatigue life and consistent hardness throughout the insert bearing
✅ Standard Grease Fitting — Enables in-service re-lubrication for extended maintenance intervals without disassembly
✅ 3,000m² Warehouse — Large Ready Stock — Fast delivery for urgent maintenance and production line requirements

Q1: What is the difference between UCP207-35MM and UCP207 inch-bore variants?
UCP207-35MM is specifically bored to 35mm metric shaft diameter. Inch-bore variants such as UCP207-20 (1-1/4"), UCP207-21 (1-5/16"), UCP207-22 (1-3/8"), UCP207-23 (1-7/16") use inch shaft sizes. Always confirm shaft diameter (metric or inch) before ordering to ensure correct fit.
Q2: Can the UC207-35MM insert be replaced separately?
✅ Yes. The UC207-35MM insert bearing can be replaced independently without replacing the cast iron housing, reducing maintenance costs. NEXANS Bearing supplies both complete UCP207-35MM units and UC207-35MM insert bearings separately.
Q3: What lubrication is recommended?
Standard lithium-based NLGI #2 grease via the standard grease fitting. Re-grease interval depends on speed, load, and environment — typically every 3–6 months for standard industrial applications.
Q4: What is the maximum shaft misalignment?
The self-aligning ball insert accommodates up to ±2° static misalignment, making the UCP207-35MM tolerant of minor shaft deflection and housing misalignment in real-world installations.
Q5: 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.
