Product Description
The UCP207-23 is a two-bolt pillow block bearing unit from the UCP200 series, combining a cast iron pillow block housing with a UC207-23 chrome steel insert bearing. Designed for standard-duty industrial applications, the UCP207-23 accepts a 1-7/16" (36.512mm) 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
UC207-23 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
45° grease fitting for convenient in-service re-lubrication

Q1: What is the difference between UCP207-23 and UCP207-35MM?
UCP207-23 = 1-7/16" (36.512mm) inch bore; UCP207-35MM = 35mm metric bore. Both use the same UCP207 cast iron housing and UC207 series insert, but with different bore sizes. The 35MM variant is specifically for metric shafts, while -23 suits imperial shaft applications. Always confirm shaft diameter before ordering.
Q2: Can the UC207-23 insert be replaced separately?
✅ Yes. The UC207-23 insert bearing can be replaced independently without replacing the cast iron housing, reducing maintenance costs. NEXANS Bearing supplies both complete UCP207-23 units and UC207-23 insert bearings separately.
Q3: What lubrication is recommended?
Standard lithium-based NLGI #2 grease via the 45° grease fitting. The angled fitting design allows re-lubrication access in confined spaces. 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 UCP207-23 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.
