Product Description
The UCP218 is a heavy-duty cast iron pillow block bearing unit with a 90mm bore diameter, combining a UC218 self-aligning insert bearing with a robust two-bolt cast iron housing. This mounted bearing unit is one of the most widely used bearing assemblies in industrial machinery worldwide — providing a complete, ready-to-install bearing solution that eliminates the need for separate shaft housing machining.
With a dynamic load rating (Cr) of 96.1kN and a static load rating (Cor) of 71.5kN, the UCP218 delivers reliable combined radial and axial load capacity for a broad range of industrial shaft applications. The UC218 insert bearing's self-aligning capability compensates for shaft misalignment and housing deflection — a critical advantage in real-world industrial installations where perfect alignment is rarely achievable.
Manufactured from high-grade cast iron housing and GCr15 / 52100 chrome steel insert bearing components, and supplied factory-direct by NEXANS Bearing from Liaocheng, Shandong, the UCP218 is available with full OEM customization for global industrial buyers, distributors, and OEM equipment manufacturers.

The UCP218 pillow block bearing is one of the most versatile mounted bearing units in industrial use, suitable for a wide range of shaft support applications:
Industrial Conveyor Systems — Tail shaft, head shaft, and intermediate shaft support bearings for belt conveyors, roller conveyors, and screw conveyors in manufacturing, logistics, and mining
Agricultural Equipment — Shaft support bearings for grain augers, combine harvesters, irrigation pumps, and other agricultural machinery where self-aligning capability and contamination resistance are essential
General Industrial Machinery — Fan shaft, pump shaft, and drive shaft support in general industrial equipment including blowers, compressors, mixers, and process machinery
Construction & Material Handling — Shaft support in concrete mixers, aggregate conveyors, and heavy material handling equipment where robust cast iron housing is required
Water & Wastewater Treatment — Pump and agitator shaft support in water treatment facilities, where sealed bearing protection against moisture and contamination is critical
Packaging & Food Processing — Conveyor and drive shaft support in packaging lines and food processing equipment requiring reliable, low-maintenance bearing solutions

Q1: What is the difference between UCP218 and UC218?
The UC218 is the insert bearing — the inner bearing component with a 90mm bore, self-aligning outer ring, and double lip seals. The UCP218 is the complete pillow block unit — the UC218 insert bearing pre-installed into a two-bolt cast iron housing (P-type). When you order UCP218, you receive the complete ready-to-mount assembly. When you order UC218, you receive only the insert bearing for use in your own housing.
Q2: What load ratings does the UCP218 provide?
The UCP218 provides a dynamic load rating (Cr) of 96.1kN — representing the constant radial load the bearing can carry for a calculated rating life of one million revolutions — and a static load rating (Cor) of 71.5kN — representing the maximum static load without permanent deformation. These ratings make the UCP218 suitable for demanding industrial conveyor, agricultural, and general machinery shaft applications with 90mm bore requirements.
Q3: What bolt size and mounting dimensions does the UCP218 use?
The UCP218 uses M22 bolts for mounting, with a bolt hole center distance of 262mm and a base width of 88mm. These standardized dimensions are consistent across all major UCP218 manufacturers, ensuring interchangeability with equivalent units from SKF, FYH, NSK, NTN, and other brands.
Q4: Is the UCP218 self-aligning? How much misalignment can it accommodate?
Yes. The UC218 insert bearing within the UCP218 unit is self-aligning, accommodating shaft misalignment through the spherical outer ring of the insert bearing. This self-aligning capability is one of the primary advantages of the UCP series — allowing the bearing to compensate for shaft deflection, housing distortion, and installation misalignment that would cause premature failure in rigid bearing arrangements.
Q5: Can the UCP218 be re-lubricated in service?
Yes. The UCP218 is equipped with a grease fitting (Zerk/nipple) that allows in-service re-lubrication without disassembly. Regular re-lubrication is recommended for applications involving high loads, elevated temperatures, contaminated environments, or extended operating cycles. Contact our technical team for lubrication interval recommendations specific to your application.
Q6: Is the NEXANS UCP218 interchangeable with SKF, FYH, NSK, or NTN equivalents?
Yes. The NEXANS UCP218 is manufactured to the same standardized UCP series dimensional specifications as equivalent units from SKF, FYH, NSK, NTN, Dodge, and other major manufacturers. The 90mm bore, 262mm bolt center, 88mm base width, and M22 bolt size are all standardized — ensuring a direct drop-in replacement for any brand's UCP218 equivalent.
Q7: What environments is the UCP218 cast iron housing suitable for?
The cast iron housing of the UCP218 is suitable for general industrial environments including manufacturing facilities, agricultural operations, construction sites, and material handling systems. For highly corrosive environments (chemical processing, marine, food-grade applications), NEXANS Bearing also offers stainless steel housing variants. Contact our sales team at export@nksbearing.com for alternative housing material options.
Q8: Can NEXANS supply UCP218 bearings with custom OEM branding?
Yes. NEXANS Bearing provides full OEM customization for the UCP218, including laser-etched or stamped custom branding on the housing, private-label packaging, and customized technical documentation. This service is available for distributors, equipment manufacturers, and industrial supply companies seeking to build their own branded bearing product line.
