Product detailed description
Bearing 22220 KJ W33 C3 RHP
The 22220 KJ W33 C3 RHP is a high-quality spherical roller bearing designed to deliver exceptional performance in demanding industrial applications. Manufactured by RHP, a renowned brand known for precision and durability, this bearing is engineered to handle heavy radial loads and moderate axial loads in both directions.
This bearing features a robust design with a self-aligning capability, allowing it to accommodate misalignment between the shaft and housing without compromising operational efficiency or lifespan. The suffixes in its designation provide detailed insights into its construction and features:
- 22220 – Denotes the bearing series and size, part of the 22200 spherical roller bearing series.
- KJ – Indicates a bearing with an extended inner ring (usually with a flange on one side) to facilitate axial location.
- W33 – Specifies a bearing with an annular groove and lubrication holes in the outer ring for improved grease circulation.
- C3 – Represents a bearing with greater internal clearance than standard, suitable for applications with thermal expansion or shaft deflection.
- RHP – The manufacturer’s trademark, assuring quality and reliability.
Typical dimensions for the 22220 series bearings are standardized, but for the 22220 model specifically, the dimensions are generally:
- Inner Diameter (d): 100 mm
- Outer Diameter (D): 180 mm
- Width (B): 47 mm
These dimensions make the 22220 KJ W33 C3 RHP ideal for heavy-duty machinery such as mining equipment, paper mills, gearboxes, and other industrial drives where durability and reliability are critical.
Key advantages of the 22220 KJ W33 C3 RHP include:
- High load-carrying capacity due to spherical roller design
- Self-aligning feature that reduces stress caused by shaft misalignment
- Enhanced lubrication capability with W33 design for prolonged bearing life
- Increased internal clearance (C3) to accommodate thermal expansion
- Robust RHP manufacturing standards ensuring long-term performance
If you require a bearing that can withstand extreme operating conditions while maintaining smooth and efficient rotation, the 22220 KJ W33 C3 RHP is an excellent choice. It is suitable for use in a wide range of industrial applications, ensuring reliability and protection against premature failure.
