Introduction Of UCFL Series Pillow Block Bearings
The UCFL series pillow block bearings are widely recognized in industrial settings for their robust design, ease of installation, and versatility in handling radial and axial loads. These bearings combine a sealed outer spherical ball bearing with a durable cast iron housing, making them ideal for applications requiring resistance to misalignment, shock loads, and harsh environmental conditions. Below is an overview of their key features, general industrial applications, and a focus on the UCFL209-28 bearing.
Key Features of UCFL Series Pillow Block Bearings
- Self-Aligning Design: Accommodates shaft misalignment up to ±3°, reducing wear and extending service life in unevenly loaded systems.
- Robust Construction: Cast iron housing provides high strength and vibration damping, while double-lip rubber seals protect against dust, moisture, and contaminants (IP54 rating).
- Easy Maintenance: Pre-lubricated with high-temperature grease, enabling long intervals between relubrication.
- Versatile Mounting: Bolt slots or through-holes allow flexible installation on frames, conveyors, or machinery bases.
-
Unique Advantages Of UCFL209-28:
- High Misalignment Tolerance: Ideal for systems with slight shaft deflection, such as long-span conveyors or agricultural machinery.
- Dust and Moisture Resistance: Sealed design ensures reliable performance in dusty farms, humid food processing plants, or outdoor environments.
- Cost-Effective Durability: Combines affordability with extended service life, reducing downtime in medium-load applications.
Typical Applications Of UCFL209-28:
- Grain Conveyors: Handles fluctuating loads and outdoor exposure in agricultural settings.
- Packaging Machinery: Supports smooth operation in high-speed labeling or filling lines.
- Pulp and Paper Processing: Withstands moisture and fibrous debris in paper roll handling systems.
- Textile Machinery: Operates quietly in spinning frames or looms with moderate vibration.
Why Choose UCFL209-28 Bearings?
The UCFL209-28 pillow block bearing exemplifies the UCFL series’ ability to deliver reliability, easy maintenance, and adaptability across diverse industrial environments. Its balance of load capacity, environmental resistance, and cost efficiency makes it a preferred choice for engineers seeking to optimize performance in medium-duty machinery.

Key Notes:
-
Radial Clearance (C3): C3 clearance (0.08–0.15 mm) allows for thermal expansion in high-speed or high-temperature applications (e.g., conveyors, fans).
-
Precision (ABEC 1): Suitable for general industrial use with moderate speed and load requirements.
-
Noise Level: Noise ≤48 dB under standard conditions; lower noise achievable with optimized lubrication.
-
Dimensions: Compatible with UC29-28 insert bearings; housing dimensions may vary slightly by manufacturer.
-
Load Ratings: Dynamic/static load ratings are approximate; verify with manufacturer data for critical applications.
-
Assumptions: Data inferred from UCFL/UC series standards (e.g., ISO 113:2015). Actual values may vary. Always consult the manufacturer’s datasheet.
