The WSBC 23028 CA/W33 spherical roller bearing, a critical component in heavy-duty industrial equipment, has gained significant traction in the mining sector due to its robust design and adaptability to harsh operating conditions. This bearing model, known for its high radial load capacity and self-aligning properties, is increasingly integrated into key mining machinery, enhancing operational efficiency and durability.

Key Applications in Mining Machinery

Crushers and Grinders

The 23028 CA/W33’s ability to handle heavy radial loads and moderate axial loads makes it ideal for crushers, where intense vibrations and uneven force distribution are common. Its self-aligning feature compensates for shaft 

misalignment, reducing wear and extending equipment lifespan

Vibrating Screens

Mining operations rely on vibrating screens to separate materials. The bearing’s optimized internal structure, including a brass cage and symmetrical rollers, ensures stability under high-frequency vibrations, a critical requirement in screening equipment

Conveyor Systems

Used in belt conveyors and bulk material handlers, this bearing supports heavy loads while maintaining smooth rotation. Its W33 designation indicates an external oil groove and three lubrication holes, enabling consistent grease supply in dusty mining environments

Gearboxes and Drivetrains

Mining gearboxes demand bearings that withstand shock loads. The 23028 CA/W33’s dynamic load rating of 538 kN (ensures reliable performance in power transmission systems

Technical Advantages

Dimensions: With an inner diameter of 140 mm, outer diameter of 210 mm, and width of 53 mm, it fits standardized mining machinery frames

Durability: The CA-type design incorporates a solid brass cage and hardened steel rollers, reducing friction and heat generation even under extreme loads

Versatility: Suitable for both cylindrical and tapered bores, it allows flexible installation in shafts of varying configurations

Leading manufacturers like Wuxi Spark Bearing Co., Ltd. have highlighted the 23028 CA/W33’s role in replacing imported bearings for domestic mining equipment, citing cost efficiency and comparable performance to global brands19. 

Additionally, its use in high-temperature environments, such as kilns and furnaces, further underscores its adaptability

As mining operations push toward automation and higher productivity, the demand for reliable components like the 23028 CA/W33 is expected to grow. Innovations in lubrication technology and material science are likely to further enhance its application scope, solidifying its position as a cornerstone of modern mining machinery.
