Structural Features
Composition
Consists of an outer spherical ball bearing with dual-sided seals mounted in a robust cast iron bearing housing. The inner ring is wider than the outer ring, which features a truncated spherical outer surface capable of self-aligning smoothly within the concave spherical surface of the housing seat.
Locking Method
Designed with a fit gap between inner bore and shaft. The inner ring is secured tightly onto the shaft via two set screws on the extended inner ring (or optional eccentric/tightening sleeve), preventing shaft slippage and ensuring dependable fixation.
Key Advantages
Easy Installation
The integrated bearing and housing unit can be bolted directly onto mechanical frames, significantly cutting down mounting time and overall assembly effort.
Automatic Self-Aligning
Compensates for initial installation errors, operational shaft inclinations, and frame deflections, maintaining smooth rotation and reducing premature wear.
Effective Sealing Protection
Dual contact seals and flingers reliably keep dust, moisture, and particulate contaminants out while retaining internal lubrication for extended durability.
Application Areas
Industrial Machinery
Conveyors, industrial mixers, ventilation fans, pump assemblies, and manufacturing equipment requiring dependable rotating shaft support.
Agricultural Machinery
Harvesters, seeders, tractors, and agricultural sorting systems operating under continuous vibration, outdoor dust, and load variations.
Construction Machinery
Cranes, concrete mixers, earthmovers, and mining/construction gear operating in demanding, heavy-load environments.

Frequently Asked Questions
What is the shaft diameter size for the UCP 206 pillow block bearing?
The UCP 206 pillow block bearing is engineered with a standard inner diameter (bore size) of 30 mm, an overall length of 159 mm, and a center height of 42.9 mm.
How is the UCP 206 bearing secured onto the shaft?
The UCP 206 bearing insert features an extended inner ring equipped with two set screws (grub screws) that securely lock onto the shaft, ensuring vibration-proof mounting and preventing axial movement.
Can this bearing handle minor shaft misalignment?
Yes. The outer spherical surface of the bearing insert matches the concave spherical seat of the cast iron housing, allowing automatic self-alignment to accommodate frame deflections and minor mounting misalignments.
What sealing protection is equipped on the UCP 206 unit?
The unit comes with dual-sided contact seals and steel flingers. This provides superior resistance against dust, debris, and contaminants, making it ideal for agricultural and industrial environments.
What is the load rating and limiting speed of the UCP 206?
The UCP 206 bearing provides a dynamic load rating of 19.47 kN, a static load rating of 11.43 kN, a fatigue load capacity of 0.475 - 0.514 kN, and a maximum limiting speed of 5000 r/min.
Do you provide custom OEM packaging and branding?
Yes, we provide full OEM support, including customized product marking, customized boxes, barcodes, pallets, and specialized export packaging tailored to your brand's specifications.
