Usage
This pillow block bearing is suited for a wide range of applications where reliable shaft support is essential. In construction equipment, it stabilizes the drive shafts of excavators, loaders, and concrete mixers, allowing smooth power transmission under heavy loads. Agricultural machinery such as combine harvesters, sprayers, and tillage equipment benefit from its rugged construction, which tolerates dust, moisture, and temperature fluctuations. The bearing also excels in conveyor systems used in material handling, mining, and manufacturing, where continuous operation and minimal downtime are critical. Its compact design enables installation in confined spaces, and the set‑screw lock simplifies maintenance by allowing quick removal and re‑installation without the need for specialized tools.

FAQ
What is the maximum load rating for the UCP204-12 bearing?
The UCP204-12 is rated for a dynamic load of approximately 2,500 lb and a static load of about 4,500 lb, making it suitable for most medium‑duty industrial applications.
Can the bearing be greased after installation?
Yes, the design includes a greasing port that allows periodic lubrication without disassembly, helping to maintain optimal performance and extend service life.
Is the set‑screw lock compatible with stainless steel shafts?
The set‑screw lock works with both carbon steel and stainless steel shafts. For stainless steel shafts, it is recommended to use a slightly higher torque setting to achieve the same clamping force.
How do I determine the correct orientation for the mounting flange?
The bearing housing is symmetrical, so orientation is not critical. However, for applications with directional loads, aligning the flange so that the set‑screws face the direction of the load can provide additional stability.
What maintenance schedule is recommended?
Inspect the bearing at least once per 1,000 operating hours, check for signs of wear, and re‑apply grease as needed. Replace the bearing if you notice excessive vibration, noise, or bearing temperature rise.
