When a shaft flexes or the housing is not perfectly true, a self-aligning bearing keeps the assembly running. NTN spherical roller bearings carry two rows of rollers on a spherical outer raceway, so the inner ring can tilt slightly inside the outer ring while the bearing still takes radial loads and axial loads in both directions. They suit heavy-duty positions in gearboxes, pumps, fans and process equipment. MR Industrial Accessories LLC supplies these bearings to customers in the United States and Latin America.

Reading the code tells you what you are ordering. Take 22205EAKW33: 222 is the medium-section spherical roller series, 05 gives the bore (multiplied by 5), EA marks the optimized internal design, K means a tapered bore with 1:12 taper, and W33 means the outer ring has a lubrication groove and holes. The same pattern applies to 22206EAKW33 and 22207EAKW33, which differ only in size.

Typical service includes gearboxes, conveyor systems, mills, screens, centrifugal pumps, industrial fans and continuous process lines. Cement, mining, steel, paper and food plants are common users. Vibration and mounting conditions that make exact alignment hard are exactly where the self-aligning feature earns its place, which is why these bearings are a frequent choice for replacement and maintenance work on critical machinery.

Selection comes down to three inputs: the radial load, the axial load and the running speed, plus the lubrication method you plan to use. A K bore bearing needs the correct adapter sleeve to seat properly and to come off easily at the next change-out. With W33, grease reaches the bearing through the housing, so relubrication does not require pulling the equipment apart. Match internal clearance and sealing to the site conditions, since dust, moisture and elevated temperatures call for extra protection.

Spherical roller bearings follow international standards, so main dimensions and load capacity line up across brands. To replace a bearing from another maker, compare the full designation: series, bore size, bore type and lubrication suffixes. MR quotes the exact code you send, in the NTN designation or a compatible equivalent. Send your part number or the bore, outer diameter and width through WhatsApp or email and the team will reply promptly, and can help you confirm the right choice.
