23030/W33

23030/W33 is a self-aligning roller bearing with an outer raceway lubrication groove and lubrication holes. Its core function is to provide stable support with high load capacity and ease of maintenance for rotating components of medium and large-sized equipment in multiple fields such as metallurgy, mining, and power, where there are misalignments in shaft systems and heavy-load conditions. It maintains a specification of 150mm inner diameter, 225mm outer diameter, and 56mm width, with a basic rated dynamic load of 531kN and a basic rated static load of 750kN. It can withstand heavy radial loads and also bear bidirectional axial loads, suitable for complex stress conditions during equipment operation. Its dual-row rollers combined with spherical outer raceway design has excellent self-aligning capabilities, capable of coping with angular deviations between the shaft and the bearing housing, easily resolving the adverse effects of shaft deflection and installation deviations, and avoiding additional stress during operation. The lubrication structure corresponding to W33 is one of its core advantages. Through the lubrication grooves and lubrication holes on the outer race, it can replenish lubricants at any time, effectively reducing operating friction and wear, extending the service life of the bearing in harsh conditions such as steel mills, metallurgical equipment, mining crushers, and boiler fans, while reducing equipment maintenance frequency and costs. Additionally, this bearing is mostly made of stamped steel cages, with a stable structure and high cost-effectiveness, with a maximum rotational speed of 3200r/min and a reference rotational speed of 2400r/min, suitable for medium-high-speed operation scenarios, fully meeting the core requirements of these industries for stable bearing load capacity, deviation adaptation, and convenient maintenance.
