Pillow Block Unit with Set Screws, Cylindrical Hole Shape, UCP (UCP208C4HR5)
Standard model number. Bearing box with a sturdy integrated structure and inserted bearing. Used with a wide range of transmission equipment. Cast iron series
[Features]
· Logical steel center: The outer wheel's outer diameter is machined into a ball surface, fitting around the center of a bearing box machined in the same way. Because both of the spherical surfaces can be aligned, this ensures logical operation of the machinery and stops erratic shaft center behavior, preventing excessive force from being applied to the bearing due to complications.
· Supply method: Simply supply fresh grease at arbitrary intervals and ensure that the bearing internal workings are ejecting old grease to the exterior as much as possible to extend working life for both grease supplies and the bearing. The cast iron series comes standard with a supply method to ensure that it can be used in severe conditions for long periods of time with complete confidence.
· Excellent sealing equipment: The bearing is double-sealed with a steel plate slinger and a heat-resistant synthetic rubber seal. Friction is low and even if the shaft tilts the seal contact is unchanged. The result is an extremely effective seal that prevents both grease leaks and contamination of the interior by external trash and moisture. Can be used with confidence even extremely poor conditions.
· This insert bearing unit with a cover can be used with confidence in poor environmental conditions such as factories engaged in steel manufacturing, milling, cement making, and casting, and in machinery for aircraft, air conditioning, and public works. The advance receiving box for units with set screws and adapters included has a steel plate or cast iron cover mounted for dust prevention, and both the bearing and the bearing box are processed with sealing equipment to improve dust-proof properties.
· Deep groove shaped internal structure: The bearing interior is identical to the deep groove ball bearing structure of the 6200 and 6300 shape. For this reason, it can support both radial and axial loads and is low noise.
· Bearing and bearing box compatibility: Because the bearing and bearing box have mutual compatibility, the bearing can be replaced on its own as necessary, which is extremely convenient.
· Easy handling: The insert bearing unit is an integrated combination of a bearing and bearing box. The bearing is preloaded with an appropriate amount of high quality lubricant grease, so it can be operating immediately as is after mounting. For this reason, there is no concern of contaminants and other materials entering the bearing during handling, preventing trouble during mounting before it occurs.
· Simple mounting to the shaft: The insert bearing unit can be mounted to the shaft on the side of the inner ring with the two included hex socket head set screws, to the inner ring using the included mounting adapter for the tapered hole in the inner diameter, or mounted with the included eccentric wheel. All of these methods are simple procedures, and the shaft machining is easy.

Frequently asked question (FAQ)
- Question: What is the key advantages of the spherical compatibility design in UCP pillow blocks?
-
Answer:
The spherical compatibility between the bearing's outer diameter and the bearing box ensures:
•Self-alignment, compensating for shaft misalignments.
•Prevention of excessive force on the bearing due to erratic shaft center behavior.
•Smooth operation and extended bearing life. - Question: How does the double-seal system enhance the UCP unit's performance?
-
Answer:
The double-seal system, comprising a steel plate slinger and heat-resistant synthetic rubber seal, provides:
•Effective grease retention to prevent leakage.
•Superior protection against contamination from dirt, debris, and moisture.
•Reliable sealing performance even when the shaft tilts or vibrates.
- Question: What is the operating temperature range?
- Answer: Bearing units filled with general-purpose grease have an operating temperature range of -15°C to +100°C.
- Question: Is there a guideline for the interval between grease replenishments?
-
Answer:
The interval varies significantly depending on usage conditions. In environments with an operating temperature of 100°C and high levels of dust, it is recommended to replenish the grease every two weeks. For more detailed information, please refer to the manufacturer's instruction manual.
Manual - Question: Can I use a different grease than the one initially filled-in?
- Answer: Generally, it is preferable to use the same grease as the initial fill. Greases are carefully manufactured by each company using selected base oils, thickeners, and additives. Mixing greases with different soap bases can alter the consistency and dropping point, significantly affecting lubrication performance. Also, mixing greases with different base oils, such as mineral and synthetic oils, can lead to incompatibility or oil separation. Even mixing greases with the same type of mineral oil from different manufacturers can cause mutual interference due to variations in oil types and additives. For general-purpose bearing units, Shell Lubricants Japan's Alvania Grease S is used.
- Question: What is the precision grade of the insert bearings?
- Answer: They correspond to JIS B1514 Grade 0.
