Model Number Meaning and Characteristics
The model designation of a bearing typically contains key information about its type and structure. For SUCPA203, it can be interpreted as follows:
S: Usually indicates that the bearing rings or rolling elements are made of stainless steel, which is key to its corrosion resistance
.UCP: This commonly refers to an integrated bearing unit where the bearing is housed in a square housing, often featuring an eccentric locking collar. This design allows the unit to be directly fixed to equipment via bolts, facilitating convenient installation
.A: This letter may indicate a specific variant or series of the bearing or housing
.203: This part of the numeric code is directly related to the bearing's size. According to common rules, multiplying the last two digits "03" by 5 gives a bore diameter of approximately 17 millimeters
.The core advantage of this design lies in integrating the bearing and housing into a compact unit, combining the corrosion resistance of stainless steel with the benefits of ease of installation and maintenance
.
If you are considering selecting and using the SUCPA203 bearing, the following suggestions might be helpful:
Must Verify Specific Parameters: Since the above information is based on inferences from model numbering rules, it is essential to obtain precise dimensional drawings, basic dynamic and static load ratings, speed limits, and other key parameters from the supplier or the brand's official website before actual purchase or use
.Pay Attention to Sealing Performance: The bearing's seals are crucial for preventing the ingress of moisture and dust. Under harsh operating conditions, it is crucial to confirm whether the product is equipped with high-performance sealing rings (such as rubber seals)
.Correct Installation and Maintenance: During installation, ensure the flatness of the housing base and tighten the mounting bolts to the specified torque. Although stainless steel is corrosion-resistant, regular inspections and maintaining proper lubrication are still recommended in demanding environments
