Product detailed description
Bearing 22312 J URB
The bearing 22312 J URB is a high-quality spherical roller bearing designed to handle heavy radial loads and moderate axial loads in both directions. Known for its durability and reliability, this bearing type is widely used in industrial machinery, including gearboxes, mining equipment, and heavy-duty conveyors.
Manufactured to meet stringent international standards, the 22312 J URB features a robust design with two rows of spherical rollers, allowing it to accommodate misalignment and reduce friction efficiently. This makes it an excellent choice for applications where shaft deflection or housing misalignment might occur.
- Type: Spherical Roller Bearing
- Designation: 22312 J URB
- Sealing: Typically open or with specific seals depending on variant
- Cage Material: Usually pressed steel or brass, ensuring stable roller guidance
The 22312 J URB is designed with a bore diameter of 60 mm, an outer diameter of 130 mm, and a width of 31 mm, conforming to the standard dimensions for 22312 series bearings. These dimensions ensure compatibility with a wide range of housings and shafts, facilitating easy replacement and maintenance.
Thanks to its spherical shape and roller design, this bearing effectively compensates for angular misalignments, making it suitable for applications where shaft deflection or mounting errors might occur. Additionally, its robust construction supports heavy loads and reduces operational wear, enhancing machinery lifespan.
Whether used in heavy machinery, industrial drives, or other demanding environments, the 22312 J URB bearing delivers consistent performance, high load capacity, and operational reliability, making it a trusted component in critical mechanical systems.
