Most of ball bearing cages are made of cold rolled steel sheet.Anf for some bearing types and special applications,cages are made of glass fiber reinforced nylon 66 plastic,phenolic or machined brass.
The material of bearing housings is gray or ductile cas iron, housings can also be made of pressed steel,stainless steel, or engineering plastics for special purposes.
Operating temperature
The bearings usually operate below the temperature of 120ºC(the measuring temperature of the outer ring is 100ºC).Grease life reduction has to be taken into account when the bearings continue to operate at a temperatuer above 70ºC.The lowest operating temperature should not be lower than -10ºC.
For higher or lower temperature application,please consult us for further information.
Mounting method of housings
The desired installation order is :first install the housing,then the shaft and bearing.The bearing units can be easily installed in principle at any place.However, in order to have a long service life, it is desired that the mounting base is flat and rigid.

Are there different grades of UCP bearings?
Yes, there are different grades or quality levels of UCP bearings, also known as pillow block bearings. These different grades are typically determined by the manufacturing standards and the specific requirements of the application. Here’s a detailed explanation of the different grades of UCP bearings:
1. Standard Grade: Standard grade UCP bearings are manufactured to meet industry-standard specifications and performance requirements. These bearings are commonly used in general industrial applications where moderate load capacities, speeds, and operating conditions are expected. Standard grade UCP bearings provide reliable performance within their specified limits and are widely available at competitive prices.
2. High-Precision Grade: High-precision grade UCP bearings are manufactured to tighter tolerances and stricter quality control standards. These bearings are designed for applications that require precise positioning, high speeds, low noise levels, and reduced vibration. High-precision UCP bearings are commonly used in industries such as robotics, machine tools, medical equipment, and optical devices. They offer superior performance and improved accuracy but are typically more expensive than standard grade bearings.
3. Specialty Grade: Specialty grade UCP bearings are designed to meet specific application requirements or industry standards. These bearings may have unique features, materials, or coatings to enhance their performance in specific environments or operating conditions. Examples of specialty UCP bearings include high-temperature bearings, corrosion-resistant bearings, food-grade bearings, and bearings for extreme load or high-speed applications. Specialty grade UCP bearings are typically selected for challenging or specialized applications and may have higher costs compared to standard grade bearings.
It’s important to note that the availability of different grades of UCP bearings may vary depending on the manufacturer and supplier. Some manufacturers may offer a range of grades to accommodate various customer needs, while others may focus on specific grades or specialize in certain industries.

What are the dimensions of standard UCP bearings?
Standard UCP bearings, also known as pillow block bearings, come in various sizes and configurations to accommodate different shaft diameters. The dimensions of UCP bearings are typically specified by the bore diameter, overall length, width, and mounting hole spacing. Here’s a detailed explanation of the dimensions commonly associated with standard UCP bearings:
- Bore Diameter: The bore diameter refers to the inner diameter of the bearing, which determines the size of the shaft that can be accommodated. Standard UCP bearings are available in a range of bore diameters, such as 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, and larger. The specific bore diameter required for your application will depend on the size of the shaft you are working with.
- Overall Length: The overall length of a UCP bearing refers to the distance between the outermost points of the bearing’s housing. It includes the length of the bearing itself and any additional extensions or flanges that may be present. The overall length can vary depending on the specific design and manufacturer, but it is typically standardized within certain size ranges.
- Width: The width of a UCP bearing refers to the measurement from one side of the bearing to the opposite side. It represents the thickness of the bearing’s housing. Similar to the overall length, the width can vary depending on the specific design and manufacturer, but it is often standardized within certain size ranges.
- Mounting Hole Spacing: UCP bearings have mounting holes on their base or flange, which are used to secure the bearing to a mounting surface. The mounting hole spacing refers to the distance between the centers of the mounting holes. This dimension is crucial for proper installation and compatibility with the corresponding mounting arrangement.
It’s important to note that the dimensions of UCP bearings can vary between manufacturers and series. Therefore, it is essential to consult the specific manufacturer’s documentation or product specifications to obtain accurate and detailed information about the dimensions of a particular UCP bearing model.
In summary, the dimensions of standard UCP bearings include the bore diameter, overall length, width, and mounting hole spacing.
