Product Description
The UCP207-20 is a two-bolt pillow block bearing unit from the UCP200 series, combining a cast iron pillow block housing with a UC207-20 chrome steel insert bearing. Designed for standard-duty industrial applications, the UCP207-20 accepts a 1-1/4" (31.75mm) 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
UC207-20 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
Unit weight: 3.6 lb (1.63 kg)

Q1: What is the difference between UCP207-20 and UCP207-21?
UCP207-20 = 1-1/4" (31.75mm) bore; UCP207-21 = 1-5/16" (33.338mm) bore. Both use the same UCP207 cast iron housing and identical external dimensions — only the bore size differs. Always confirm shaft diameter before ordering to ensure correct fit.
Q2: What is the FHP207-20G cross reference?
FHP207-20G is an alternative part number designation used by some distributors for the same UCP207-20 unit. The "FHP" prefix denotes a fractional horsepower / light-duty designation used in certain North American distribution channels, but the bearing unit is dimensionally and functionally identical.
Q3: Can the UC207-20 insert be replaced separately?
✅ Yes. The UC207-20 insert bearing can be replaced independently without replacing the cast iron housing, significantly reducing maintenance costs. NEXANS Bearing supplies both complete UCP207-20 units and UC207-20 insert bearings separately.
Q4: 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.
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.
