A long-life bearing with grease sealed that achieves a lifespan up to 3.7 times longer compared to conventional NTN products!

The "WA type" is a sealed self-aligning roller bearing from the ULTAGE series, developed to meet the demands for "long life," "improved reliability," and "better handling" required in various industrial machinery. By adopting a "cage type" steel plate stamped retainer that maximizes the roller diameter and number, it achieves high load capacity and long life. The "contact type" dust seal, with a reduced seal volume, prevents the intrusion of foreign substances. By standardly incorporating oil holes and oil grooves on the outer diameter surface of the outer ring, it ensures reliable grease lubrication inside the bearing. There is no need for cleaning and grease filling during bearing assembly. 【Features】 ■ World-class high load capacity (adoption of large diameter rollers) ■ Extended maintenance intervals ■ Downsizing and weight reduction ■ Prevention of foreign substance intrusion ■ Contribution to extended lubrication intervals ■ Structure that facilitates easy entry of lubricants *For more details, please download the PDF or feel free to contact us.
