Product Overview: The 21304 Spherical Roller Bearing
The 21304 bearing is a high-performance component within our 21300 Series Spherical Roller Bearings, engineered for exceptional reliability in demanding industrial environments. With precise dimensions of 20mm bore diameter, 52mm outer diameter, and 15mm thickness, this bearing is designed to accommodate heavy radial and axial loads, even when operating under conditions of misalignment. Its robust construction features two rows of symmetrical rollers, a common spherical outer ring raceway, and two inner ring raceways inclined at an angle to the bearing axis, allowing it to self-align and compensate for shaft deflection or housing deformation.
As a leading supplier of industrial bearings and mechanical parts, we ensure that our 21304 bearings meet stringent industry standards, offering extended service life and reduced maintenance requirements. These bearings are indispensable in machinery where severe operating conditions, such as shock loads, heavy vibrations, and significant shaft deflections, are common. Explore our comprehensive selection of spherical roller bearings to find the optimal solution for your heavy-duty applications.
