The Timken Company E-P2B-TRB Pillow Block Bearing

Description:

The Timken E-P2B-TRB is a Type E two-bolt pillow block mounted tapered roller bearing designed to provide exceptional support for shafts subjected to heavy combined radial and axial loads. This mounted bearing unit features a rugged cast iron housing with a precision-matched tapered roller bearing insert that offers superior load-carrying capacity, shaft alignment, and extended service life compared to conventional ball bearing units. The bearing is grease lubricated and protected by advanced sealing to help retain lubricant while minimizing contaminant ingress in demanding industrial environments. It is widely used in conveyors, aggregate processing equipment, mining machinery, lumber mills, agricultural equipment, bulk material handling systems, and heavy-duty power transmission applications. Maintenance teams, OEMs, and system integrators specify the E-P2B-TRB for equipment replacement, retrofit projects, expansion, and preventive maintenance to improve equipment reliability and reduce downtime.

Applications:

The Timken E-P2B-TRB pillow block bearing is engineered for industrial machinery requiring high radial and thrust load capacity, reliable shaft support, and long operating life under severe service conditions. Its tapered roller bearing design accommodates combined loads while the heavy-duty cast iron housing provides excellent structural rigidity. Typical applications include conveyors, mining equipment, aggregate processing plants, sawmills, cement plants, agricultural machinery, material handling systems, and industrial power transmission equipment.
