249/800CA/W33

249/800CA/W33 is a super-large and super-heavy-duty self-aligning roller bearing. Its core function is to provide a key component for stable support, automatic alignment, and high durability guarantee for low-speed ultra-heavy equipment that requires long-term lubrication and is subject to extreme radial loads, certain axial loads, installation deviations, or shaft deflection. It achieves this through its core structure that is adapted to harsh conditions: The "CA" marking indicates the use of symmetrical spherical rollers + double flange on the inner ring + brass-cast cages, which can enhance heavy-load bearing capacity and impact resistance, meeting the high-load requirements of ultra-heavy equipment; The "W33" design of the outer ring oil grooves and oil holes allows for connection to a centralized lubrication system for continuous lubrication, reducing maintenance frequency under low-speed heavy-load conditions; The spherical raceways of the outer ring can automatically compensate for equipment installation errors and shaft deflection, avoiding local stress concentration.
