Materials of 4-Bolt Round Flanged Unit
Cast Iron
Known for its durability and excellent vibration damping properties, ideal for heavy-duty applications.
omposite (Black)
Lightweight and corrosion-resistant, suitable for environments where chemical exposure is a concern.
Food-Compatible Composite (Blue)
Designed for hygienic applications, these composites meet stringent food industry standards.
Spheroidal Graphite Cast Iron
Offers superior strength and toughness, making it suitable for high-load conditions.
Pressed Steel
Cost-effective and lightweight, commonly used in applications with lower load requirements.
Stainless Steel
Highly resistant to corrosion and ideal for applications in harsh or wet environments.

Bearings are precision parts that can easily be contaminated or damaged if not cared for correctly. Always wear gloves when handling bearings to prevent corrosion from skin oils or sweat.
Store unused bearings horizontally in their original packaging in a clean, dry area at room temperature. This prevents moisture, dust, and dirt from entering the bearings prior to installation. Dropping or mishandling bearings can cause unseen damage that might not manifest until a later date.
Application Scope of 4-Bolt Round Flanged Unit

Precautions for Using the 4-Bolt Round Flanged Unit
Bearings should be stored in a clean, moisture-free environment to prevent rust and contamination. They should also be kept in their original packaging until they are ready for installation to protect against environmental factors and handling damage that could compromise their performance.
The installation area should be free of any contaminants to prevent them from being introduced to the bearing surfaces. Using clean installation tools and wearing gloves can significantly reduce the risk of contamination, thus ensuring the reliability and efficiency of the bearings.
