23064CA Spherical Roller Bearing

Self-Aligning Capability: The spherical outer raceway accommodates up to 2 degrees of shaft misalignment without any loss of load capacity.
Colossal Load Rating: Specifically engineered to absorb extreme radial forces and heavy shock impacts in slow-moving machinery.
Machined Brass Cage (CA): Provides superior strength, reduces friction, and withstands extreme rotational vibration better than stamped steel.
Advanced Lubrication (W33): The outer ring features a specialized groove and lubrication holes, ensuring grease or oil reaches the critical internal rolling elements immediately.

Product Introduction

The 23064CA/W33 is an engineering marvel designed for the most brutal industrial environments on the planet. With colossal dimensions of 320 x 480 x 121 mm, this spherical roller bearing boasts an incredible capacity to handle immense radial payloads while automatically compensating for severe shaft misalignment and heavy structural deflection. Manufactured within our premier heavy-machinery components division, this bearing utilizes a precision-machined solid brass cage (CA design) to guide the massive rollers through extreme shock loads. The integrated W33 lubrication groove ensures optimal oil flow to the core of the bearing. Through uncompromising metallurgical standards and elite quality control, we deliver a component that guarantees uninterrupted production in mining, steel rolling, and heavy material handling.

Applications

Main shafts in heavy mining crushers, pulverizers, and vibrating screens.
Large-scale paper making machinery and calendar rolls.
Steel rolling mills, continuous casters, and heavy marine propulsion shafts.

FAQ

Q: What does the "CA" suffix mean?
A: The "CA" suffix indicates that the bearing utilizes a one-piece, precision-machined brass cage with retaining flanges on the inner ring, designed for ultimate strength in high-vibration environments.
Q: Why is there a groove on the outside?
A: The W33 designation means there is a lubrication groove and three holes on the outer ring. This allows maintenance teams to pump grease directly into the center of the bearing while it operates.

OEM & Custom Service

For our heavy-industry B2B partners, we offer custom internal clearances (such as C3 or C4) to manage the massive thermal expansion found in steel mills. We also provide customized case-carburizing treatments for extreme shock-load applications.

Packing & Delivery

Due to its massive size and weight, the 23064CA/W33 is heavily coated in industrial preservatives, vacuum-sealed in thick barrier film, and shipped individually in reinforced, custom-built wooden crates to guarantee pristine delivery to global heavy-industry sectors.
