The WSBC NU319-E-M1-C3 cylindrical roller bearings have emerged as a critical component in enhancing the operational efficiency and reliability of oil drilling platforms. Designed to withstand extreme radial loads and harsh environmental conditions, these bearings are engineered to meet the rigorous demands of the petroleum industry.

Key Product Features

High Load Capacity and Durability

The NU319-E-M1-C3 boasts a dynamic radial load capacity of 390,000 N and a static radial load capacity of 380,000 N, making it ideal for heavy-duty applications such as drill rigs and rotating machinery .  Its robust construction, 

featuring iron-based rings and rollers, ensures longevity even under continuous high-stress operations .

Precision Engineering for Harsh Environments

With an internal clearance designation of C3, this bearing accommodates thermal expansion and misalignment caused by uneven loads or temperature fluctuations common in offshore drilling . The brass cage design enhances stability and reduces friction, supporting speeds up to 5,300 RPM (limiting speed) and 3,600 RPM (reference speed).  

Temperature and Lubrication Adaptability

Operating effectively within a temperature range of -30°C to 150°C, the bearing is compatible with both grease and oil lubrication systems, ensuring optimal performance in diverse climatic conditions . This flexibility is crucial for offshore platforms exposed to variable temperatures and corrosive seawater.

Ease of Maintenance and Installation

As a single-row cylindrical roller bearing with a separable design, the NU319-E-M1-C3 allows for straightforward installation and replacement, minimizing downtime during critical drilling operations . 

Industry Applications and Advantages

Cylindrical roller bearings like the NU319-E-M1-C3 are widely used in oil drilling equipment, including rotary tables, hoisting systems, and mud pumps, where radial load support and precision are paramount .Their ability to handle 

misalignment and axial displacement reduces wear on adjacent components, extending the lifespan of entire systems .

Despite China’s growing dominance in bearing production, high-end products like the NU319-E-M1-C3 highlight the industry’s push toward overcoming technical bottlenecks in precision manufacturing. With over 80% of domestic bearings still classified as mid-to-low tier, innovations in materials and heat treatment processes—such as those employed in this bearing—are pivotal for reducing reliance on imports
