When a misaligned shaft or an undersized bearing causes unexpected downtime on your conveyor, fan assembly, or agricultural equipment, the cost adds up fast. Engineers, fabricators, and serious DIYers who need a dependable, drop-in bearing solution turn to UCPH-series pillow block mounted bearings — a workhorse design built to handle radial loads, minor shaft misalignment, and continuous rotation without complaint.
Each unit pairs a cast iron two-bolt pillow block housing with a self-aligning ball bearing insert (UC-series). Available bore sizes span 20 mm to 50 mm (approximately 0.79 in to 1.97 in), covering UCPH204 through UCPH210. The housing is finished with a protective coating to resist everyday workshop and light-outdoor exposure, while the bearing insert is pre-greased and sealed for maintenance-reduced operation.
Typical use cases include conveyor roller shaft support, electric motor and pump mounting, agricultural machinery drive shafts, and CNC or woodworking machine spindle support — anywhere a two-bolt pillow block bearing with a specific bore diameter is required for secure, low-vibration shaft retention.
Robust cast iron construction provides structural rigidity and vibration damping, keeping the bearing insert firmly seated under continuous radial load.
The UC-series insert accommodates minor shaft misalignment (typically ±2°–3°), reducing stress on the shaft and extending service life in real-world installations.
Seven size options from UCPH204 (20 mm bore) to UCPH210 (50 mm bore) let you match the bearing precisely to your shaft diameter without adapters.
Factory-applied grease and dual-lip seals minimize maintenance intervals and protect the rolling elements from dust and light moisture ingress.
Standard two-bolt base allows straightforward bolt-down installation on steel frames, wooden beams, or fabricated brackets with common hardware.
The UC insert includes a set-screw collar for positive shaft retention, preventing axial creep during operation without requiring a machined shaft shoulder.

Match the bore diameter to your shaft's outer diameter. UCPH204 fits a 20 mm shaft, UCPH205 fits 25 mm, UCPH206 fits 30 mm, UCPH207 fits 35 mm, UCPH208 fits 40 mm, UCPH209 fits 45 mm, and UCPH210 fits 50 mm. Select the variant above that corresponds to your shaft size.
Dynamic load capacity varies by size — larger bore variants carry higher loads. As a general guide, UC204–UC210 inserts typically handle dynamic radial loads in the range of 12–30 kN depending on the specific model. Consult the bearing datasheet for your selected size for precise load ratings and speed limits.
The cast iron housing has a protective coating suitable for dry indoor and light-exposure environments. For consistently wet, washdown, or corrosive conditions, consider stainless steel or polymer-housed alternatives. The dual-lip seals do provide protection against dust and light moisture splash.
Yes. The UC-series self-aligning ball bearing insert accommodates angular misalignment of approximately ±2°–3°, making it suitable for installations where perfect shaft-to-housing alignment is difficult to achieve. Exceeding this range will reduce bearing life.
The inserts are pre-greased at the factory and sealed for reduced-maintenance operation. However, they include a grease fitting (zerk fitting) so you can re-grease them periodically in demanding or high-temperature applications to extend service life.
UCPH designates a standard two-bolt pillow block (side-mount base). UCF refers to a four-bolt square flange housing, and UCFL refers to a two-bolt oval flange housing. Choose UCPH when you need a base-mounted, bolt-down configuration on a horizontal or angled surface.
Yes — UC204 through UC210 insert bearings are widely available as standalone components. If the housing remains undamaged, you can replace only the insert, which is a cost-effective maintenance option for high-cycle applications.
