Product Introduction

The 23326MB is a heavy-duty, self-aligning spherical roller bearing designed to deliver robust load support in severe operating conditions. Measuring 130 x 280 x 112 mm, this bearing features a solid machined brass cage (MB designation) that provides exceptional guidance for the rolling elements, even under extreme vibration and shock loads. Manufactured in our advanced production facilities using high-purity GCr15 steel, the 23326MB automatically compensates for shaft misalignment and mounting deflections. Through rigorous quality control and micro-finished raceway geometry, we ensure maximum fatigue life and reliable power transmission for global heavy-industry B2B partners.

Applications

Heavy-duty mining machinery and vibratory crushers.
Paper mill processing gearboxes and calendar rolls.
Marine propulsion drives and steel mill rolling machinery.

FAQ

Q: What is the advantage of the "MB" machined brass cage?
A: Machined brass cages offer greater mechanical strength, lower friction, and higher temperature capability compared to standard stamped steel cages, making them ideal for heavy vibration.
Q: Does this bearing feature lubrication grooves?
A: Yes, standard production includes an annular lubrication groove with three lube holes on the outer ring for efficient re-greasing.
