UCPH200 Series Pedestal Base Pillow Block Bearing Units — High-Pedestal Housing, Setscrew Locking
Standard pillow blocks position the shaft centreline at a moderate height above the mounting surface. The UCPH200 series extends this to an exceptional height through a pedestal base: a tall, narrow column section between the standard hollow base foot and the housing body. This pedestal raises the shaft centreline (H0 dimension) to heights ranging from 101 mm at 12 mm bore to 197 mm at 60 mm bore — roughly double the H0 of an equivalent UCP200. This extended height solves a specific engineering problem that arises when a shaft must pass over an obstacle, clear a coupling that protrudes from an adjacent shaft, or run at a height dictated by the driven equipment.
Pedestal Design — When Standard Height is Not Enough
The most common application for pedestal pillow blocks is the shouldered shaft scenario: a shaft with a large-diameter shoulder or coupling must pass through the bearing mounting zone, but the shoulder diameter exceeds the clearance that a standard housing provides between the shaft and the mounting surface. Standard options include fitting a standard pillow block over the shaft end before the shoulder is machined — not possible in retrofit situations; using a split housing — adds cost and complexity; or using a pedestal pillow block — the tall column raises the housing body high enough that the shoulder passes below the housing base without interference.
Key Features
▲
Pedestal Column — Extended H0
Integral cast column raises shaft centreline to 101–197 mm above mounting surface. Double the H0 of equivalent UCP200 bore sizes. Solves shouldered-shaft clearance problems without separate plinths.
🔧
Dual Setscrew Locking
Same 120° dual setscrew retention as UCP200. No change to maintenance tooling or procedure.
↔
Self-Aligning Wide Inner Ring Insert
Spherical OD UC insert compensates angular misalignment up to 2°. Critical in pedestal installations where mounting surface flatness deviations translate to larger angular offsets at the elevated bearing position.
⚙
Integral Cast Pedestal
Pedestal column and housing body are cast in one piece — no bolted joints between column and housing. Full housing stiffness is maintained through the column section.
▭
Standard Hollow Base Foot
Base foot maintains the same J (bolt circle) and A dimensions as UCP200 for equivalent bore sizes. Existing UCP200 mounting holes can be reused when upgrading.
📏
Metric and Inch Bore
Full metric bore range 12–60 mm with inch bore insert variants. UC insert bearing interchangeable with UCP200 for same bore size.

H = total height from base to top of housing. H0 = shaft centreline height above mounting surface (key clearance dimension). H0 is significantly higher than UCP200 equivalent. Verify lateral stability of pedestal column under off-axis loads before specifying in high-vibration environments.
Applications
⚙
Shouldered Shaft Clearance
Drive shafts with large flanged couplings, timing pulleys, or shaft shoulders that exceed the clearance provided by a standard UCP200. Pedestal raises housing body clear of the obstruction without dismantling the shaft.
💧
Pump & Blower Height Matching
Centrifugal pump and blower units mounted at a fixed shaft centreline height. UCPH200 matches this height without a separate plinth, maintaining bearing concentricity.
🌿
Agricultural PTO Driveline Supports
PTO shaft intermediate bearing supports on implement frames where the shaft must clear frame members and the bearing housing must sit above the frame rail.
▶
Conveyor Over-Frame Shaft Supports
Return roller and snub pulley shafts on conveyor frames where the shaft must clear the conveyor frame cross-members by more than a standard pillow block can span.
⛏
Mining Equipment Elevated Shaft Supports
Drive shafts on ore bins, chutes, and storage silos where access constraints create shaft centreline heights that only a pedestal housing can serve in a standard two-bolt format.
🔄
Retrofit Without Shaft Disassembly
When a shaft shoulder or coupling prevents installation of a standard housing and the shaft cannot be disassembled. UCPH200 can often be positioned over the shaft after the obstructing component is fitted.

Installation Considerations for Pedestal Housings
The pedestal column concentrates the structural moment from off-axis loads into a taller, narrower cross-section than a standard pillow block foot. In high-vibration environments or where significant side loads are present, verify that the pedestal column section provides adequate bending stiffness for the application. In standard industrial and agricultural applications with moderate loads, the integral cast column provides sufficient rigidity. For very large side loads at the 50–60 mm bore range, the UCPX00 medium duty series with a separate pedestal plinth may provide higher total stiffness. For installations where the shaft centreline must be even higher than UCPH200 provides, contact us with the required H0 — custom pedestal heights are available as engineered-to-order items.
Frequently Asked Questions
What is the H0 dimension?
H0 = shaft centreline height above mounting surface. UCPH201: H0=101 mm. UCPH212: H0=197 mm. Approximately double equivalent UCP200 bore sizes.
Is the pedestal column part of the casting?
Yes — integral one-piece casting. No bolted joint between column and housing body.
Compatible with existing UCP200 mounting holes?
Base J and A match UCP200 for same bore. But higher H0 means adjacent guards and components may need repositioning.
What is the MOQ?
Standard parts: quantity-based MOQ. Samples 1–5 pcs. Multi-model from USD 1,500. Retail 1–2 pcs not accepted.
