DODGE P4 BS2 400S Heavy Duty Pillow Block Bearing | 4 Inch Spherical Roller Bearing Unit | High-Performance Mounted

The DODGE P4 BS2 400S is a premium, heavy-duty mounted spherical roller bearing unit designed for the most demanding industrial applications, including mining, aggregates, cement, and power generation. This 4-bolt pillow block housing accommodates a 4.0000-inch shaft and utilizes a high-capacity double-row spherical roller insert, ensuring maximum load distribution and exceptional resistance to shock loads and misalignment. Engineered for reliability, the unit features the BS2 seal arrangement (typically a high-contact, multi-lip seal or labyrinth combination) to aggressively exclude contaminants and retain lubricant, drastically extending bearing service life even in environments characterized by high dust, moisture, and extreme temperatures. Its robust cast housing is designed for optimal heat dissipation and structural integrity under constant heavy operation, minimizing the risk of catastrophic failure and premature wear. Investing in the P4 BS2 400S unit translates directly into reduced operational costs and maximum uptime. The bearing’s self-aligning capabilities compensate for shaft deflection and mounting inaccuracies up to 1.5 degrees, ensuring smooth rotation and preventing destructive edge loading. Maintenance is simplified through easily accessible lubrication points and robust mounting surfaces. Ideal for critical drive applications such as conveyors, screens, and kiln supports, this DODGE unit provides a reliable, drop-in replacement or upgrade path for any system requiring superior load ratings and unparalleled durability in harsh, continuous-duty environments. This unit guarantees performance where standard bearings simply cannot cope.
