The SW B228 is a robust, single-row deep groove ball bearing engineered for high performance and reliability in demanding industrial environments. Featuring precision-machined races and manufactured from high-carbon chromium bearing steel (AISI 52100 equivalent), this bearing delivers exceptional rotational accuracy and minimal friction. The B228 utilizes a durable cage construction to handle significant radial and axial loads, supporting rotation speeds suitable for applications up to 12,000 RPM (limiting speed for oil lubrication). Its 2RS designation indicates double-lip synthetic rubber seals, which effectively retain factory-fill lithium grease while protecting the internal components against contaminants, moisture, and dust, significantly extending service life and reducing the necessity for frequent lubrication.
Designed as a universal replacement or OEM component, the SW B228 ensures maximized uptime and reduced maintenance expenditure across critical machinery. Its optimized internal geometry guarantees smooth, quiet operation, making it ideal for electric motors, high-volume pumps, industrial fans, and precision gearboxes. Choosing the SW B228 means investing in reliability; the superior sealing technology combined with strict adherence to ISO tolerance standards (P0/ABEC 1) guarantees a predictable lifespan even under continuous operation. This bearing is a high-value solution for organizations focused on minimizing operational disruptions and maximizing machine efficiency.
