Spherical Roller Bearing 238/850CAW33C3｜QIBR Heavy-Duty Bearing for Large Industrial Equipment

1.Product Overview

The QIBR 238/850CAW33C3 spherical roller bearing is a large-size, heavy-duty bearing designed for demanding applications with high impact loads, continuous operation, elevated temperatures, and potential misalignment.

Featuring a reinforced CA brass cage and W33 lubrication groove with oil holes, this spherical roller bearing delivers stable performance, long service life, and reliable lubrication in harsh working conditions.

2. Key Features

CA Brass Cage (CA Design)

• Machined brass cage with high strength and excellent wear resistance
• Stable roller guidance under heavy and shock loads
• Enhanced durability and operational reliability

• Double-row spherical roller design
• Optimized roller profile and raceway structure
• Supports extremely high radial and axial loads, ideal for large industrial machinery

Excellent Self-Aligning Performance

• Automatically compensates for minor angular misalignment (1–2°)
• Reduces stress from installation errors or shaft deflection
• Ensures smooth operation in applications with vibration or uneven load distribution

W33 Lubrication Groove + Oil Holes

• Supports centralized and on-line lubrication systems
• Ensures consistent oil film formation under heavy loads
• Reduces temperature rise and prolongs bearing life

C3 Internal Clearance

• Suitable for applications with high operating temperatures
• Prevents clearance reduction caused by thermal expansion
• Minimizes friction and ensures stable running at all times

3.Applications
