📝 Category Detail

5200E and 5300E series are high-performance double-row angular contact ball bearings with an integrated, non-separable structure. Designed with a large contact angle, they deliver exceptional combined radial and bidirectional axial load capacity, high rigidity, and precise shaft positioning, making them ideal for applications requiring compact design and heavy load support.

The E suffix denotes an enhanced internal geometry with optimized ball size and raceway design, significantly improving load capacity, rotational accuracy, and service life compared to standard series. Manufactured from premium GCr15 (100Cr6) high-carbon chromium bearing steel with precision heat treatment and strict quality control, these bearings ensure excellent wear resistance, dimensional stability, and reliable performance under high-speed and heavy-load conditions.

5200E series is optimized for medium-load, high-speed applications, while 5300E series offers enhanced heavy-load capacity, covering a full range of metric sizes for diverse industrial needs.
