Product Introduction

The 53868/CA W33 is a severe-duty spherical roller bearing engineered to excel under extreme shock loads, heavy continuous radial pressure, and harsh operating environments. Featuring the robust "CA" construction, this bearing incorporates a single-piece precision-machined solid brass cage, symmetrical barrel rollers, and retaining ribs on the inner ring. Additionally, the "W33" feature provides a circumferential lubrication groove and three oil holes on the outer ring, ensuring direct grease delivery straight to the rolling elements. It is an indispensable, high-reliability component for heavy mining, stone crushing, and vibratory equipment operators.

Applications

Vibrating screens, stone crushers, and mining pulverizers.
Metallurgical equipment, continuous casters, and rolling mill drives.
Heavy marine propulsion shafting and offshore equipment.

FAQ

Q: What is the main advantage of the CA designation over a steel cage?
A: The CA solid brass cage provides far higher resistance to vibration, fatigue, and mechanical shock loads typical of mining and quarry equipment.
Q: Can you provide C3 internal clearance for high-temperature applications?
A: Yes, C3, C4, or custom radial clearances can be supplied based on your operational thermal requirements.
