Pillow Block Bearings
Overview
Talos Bearing offers a comprehensive range of mounted bearing products:
- Standard cast-iron UCP/UCPA mounted bearings for general industrial drive equipment;
- Eccentric locking and adapter sleeve mounted bearings designed for high-vibration environments or bidirectional rotation applications;
- Stamped steel mounted bearings that meet cost requirements for light-duty OEM applications;
- Stainless steel and thermoplastic mounted bearings suitable for washdown and corrosive environments;
- Heavy-duty split SN/SNL housings for large-scale shaft systems in the mining, steel, and paper industries.
All mounted bearings are pre-lubricated at the factory and ready for immediate installation; detailed technical specifications are available upon request.
Features & Benefits
- Self-aligning spherical insert compensates for ±2°–3° of static shaft misalignment, eliminating edge-loading stress that shortens bearing life in field installations where perfectly level mounting is rare.
- Pre-lubricated, ready-to-install design with a grease fitting for relubrication — no bearing press, no machined housing bore, no specialized tooling required at installation.
- Locking method matched to duty cycle — set screw for unidirectional light duty, eccentric collar for vibration and reversing drives, adapter sleeve for heavy-duty and field-serviceable large-shaft applications.
- Material range covers every environment — cast iron for general industry, pressed steel for cost-driven light duty, stainless steel and thermoplastic for washdown, food, and corrosive service.
- Split housing option (SN/SNL) allows bearing inspection and replacement without removing the shaft, cutting maintenance downtime on large continuous-process lines.

Applications & Industries
- Material handling & conveyor systems — UCP and UELP units support idler and drive pulley shafts on belt and screw conveyors, where the two-bolt mount simplifies alignment across long frame runs.
- Agriculture — pressed-steel and UCPA adapter-sleeve units support augers, PTO shafts, and harvester drivelines, where field replacement without specialized tools is a practical requirement.
- Mining & aggregate processing — heavy-duty SN/SNL split plummer blocks with spherical roller inserts support large-diameter shafts on crushers, screens, and overland conveyors under high shock load.
- HVAC fans & blowers — cast iron UCP units support fan shafts where moderate speed and continuous duty cycle call for reliable, low-maintenance self-aligning support.
- Water & wastewater treatment — stainless steel and thermoplastic units support screw pumps, clarifier drives, and aerator shafts in wet, often chemically aggressive environments.
- Food & beverage processing — stainless steel and thermoplastic washdown-rated units meet hygienic requirements for conveyor and mixer drive shafts subject to regular high-pressure cleaning.
FAQs
What is the difference between a pillow block bearing and a flange bearing?
A pillow block (plummer block) mounts with the shaft running parallel to the base, typically using two bolt holes. A flange bearing mounts perpendicular to a wall or vertical panel, typically using four bolts, with the shaft passing through the panel. Both commonly use the same UC-type insert internally — only the housing shape and mounting orientation differ.
Can I get pillow block bearings in stainless steel for food-grade applications?
Yes. Talos Bearing supplies 304 and 316 stainless steel housings paired with stainless or coated inserts for food, beverage, and pharmaceutical washdown environments. Specify your contact-surface and cleaning-chemical requirements so we can confirm the correct grade and seal type.
What's the difference between set screw and eccentric collar locking, and which one should I choose?
Set screw locking is lower cost and suited to unidirectional rotation under light-to-moderate load. Eccentric collar locking grips more securely under vibration and bidirectional rotation. Choose based on your drive’s rotation pattern and vibration level — see Section 9 for the full decision framework.
How often should pillow block bearings be relubricated?
Under normal ambient conditions, every 1,000–2,000 operating hours or every 6 months, whichever comes first. In wet, dusty, or high-temperature environments, shorten the interval to 500–1,000 hours. Use NLGI Grade 2 lithium-based grease unless your application specifies otherwise.
Are Talos Bearing pillow block bearings compatible with SKF, Timken, FYH, and NTN equivalents?
Yes. Standard UCP/UCPA series housings and inserts follow ISO 113, ISO 3228, and ISO 9628 boundary dimensions, making bore size, bolt spacing, and base-to-center height interchangeable with major-brand equivalents in the same size designation.
