Note: UCP205-15 uses a 15/16" (23.813mm) bore — a fractional inch size common in North American agricultural and light industrial machinery. Always verify shaft diameter before ordering, as the adjacent UCP205-14 (7/8") and UCP205-16 (1") share the same housing but differ in bore.

Q1: What is the bore size of UCP205-15 in mm?
The UCP205-15 bore is 15/16" = 23.813mm. This is a fractional inch size common in North American machinery. It is NOT the same as any standard metric bore. Always verify shaft diameter with a micrometer before ordering.
Q2: What is the difference between UCP205-15 and UCP205-16?
Both use the same UCP205 cast iron housing with identical external dimensions (h=36.5mm, a=140mm, e=105mm). The only difference is bore size: UCP205-15 = 15/16" (23.813mm), UCP205-16 = 1" (25.4mm). Choose based on your exact shaft diameter.
Q3: What is the Dodge equivalent for UCP205-15?
The Dodge equivalent is #123805 — a direct cross-reference with identical 15/16" bore, housing dimensions, and load ratings.
Q4: What is the Seal Master equivalent for UCP205-15?
The Seal Master equivalent is NP-15 — a direct cross-reference confirmed by both NEXANS official interchange list and Rainbow Precision Products/FYH data.
Q5: Can the UC205-15 insert be replaced separately?
✅ Yes. The UC205-15 insert bearing can be replaced independently without replacing the cast iron housing, significantly reducing maintenance costs. NEXANS Bearing supplies both complete UCP205-15 units and UC205-15 insert bearings separately.
Q6: 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.
