Product Introduction

The 6210-ZZ is a highly versatile, single-row deep groove ball bearing designed to accommodate high rotational speeds and moderate radial/axial loads. With standard metric dimensions of 50 x 90 x 20 mm, this bearing is equipped with dual metal shields (ZZ) that protect the internal rolling elements from dust and larger debris while retaining the factory-filled lubricant. Produced with ultra-clean GCr15 high-carbon steel and precision-honed raceways, the 6210-ZZ guarantees exceptionally low friction, quiet operation, and prolonged service life for international industrial and mechanical equipment manufacturers.
