Note: UCP206-17 uses a 1-1/16" (26.988mm) bore — a common fractional inch size in North American agricultural and industrial machinery. Always verify shaft diameter before ordering, as the adjacent sizes UCP206-16 (1") and UCP206-18 (1-1/8") share the same housing but differ in bore.

Q1: What is the bore size of UCP206-17 in mm?
The UCP206-17 bore is 1-1/16" = 26.988mm. 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 UCP206-17 and UCP206-18?
Both use the same UCP206 cast iron housing with identical external dimensions (h=42.9mm, a=165mm, e=120.7mm). The only difference is bore size: UCP206-17 = 1-1/16" (26.988mm), UCP206-18 = 1-1/8" (28.575mm). Choose based on your exact shaft diameter.
Q3: What is the NAP206-17 interchange?
NAP206-17 is a direct equivalent to UCP206-17 from the NAP bearing brand. Both units share identical bore (1-1/16"), housing dimensions, load ratings, and mounting bolt pattern.
Q4: Can the UC206-17 insert be replaced separately?
✅ Yes. The UC206-17 insert bearing can be replaced independently without replacing the cast iron housing, significantly reducing maintenance costs. NEXANS Bearing supplies both complete UCP206-17 units and UC206-17 insert bearings separately.
Q5: 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.
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.
