Design Features of CE7021ZR Bearing

CE7021ZR Bearing has a single row of balls placed in a way that the contact angle between the balls and the raceway is optimized for handling combined axial and radial loads. Balls in this Bearing are made from zirconia (ZrO2), a ceramic material known for its exceptional strength and resistance to wear and corrosion. CE7021ZR bore dia is 105 mm. Its out dia is 160 mm. CE7021ZR width is 26 mm. It is designed for applications that demand high precision and speed.
