239/500-K-MB

The 239/500-K-MB is a heavy-duty spherical roller bearing engineered to manage extreme radial loads and multi-directional axial forces in the most demanding environments. Featuring a substantial 500mm bore, a 670mm outside diameter, and a 128mm width, this unit is built with a 1:12 tapered bore (K), making it highly compatible with adapter sleeves for simplified mounting and dismounting on large-scale shafts. Its core design incorporates two rows of symmetrical rollers and a common spherical outer ring raceway, a configuration that excels at compensating for shaft deflections and housing misalignments without compromising internal friction or operational heat levels.

Precision and durability are further enhanced by the MB suffix, denoting a solid brass cage guided by the inner ring. Unlike standard pressed steel cages, this machined brass structure provides superior stability under high-speed rotations and heavy vibration, ensuring the rollers remain perfectly aligned even during fluctuating load cycles. To support long-term reliability and ease of maintenance, the bearing includes a standard W33 lubrication system, featuring a circumferential groove and three lubrication holes. This allows for direct grease or oil delivery to the rolling elements, making the 239/500-K-MB a preferred choice for large-scale industrial machinery, such as mining crushers, paper mills, and heavy-duty transmission systems where downtime is not an option.
