spindle bearing (bore 30-40mm)


spindle bearing, bore size 30~40mm

More details


Spindle bearing are of high precision grade P4, P2, or beyond P2. Standard series utilizes bearing steel material (100Cr6/SAE52100/SUJ2) for the rings, PEEK, nylon, phenol-formaldehyde resin for cage. A precision hybrid bearing utilizes ceramic material Si3N4 as ball material. They work individually, or with another or more bearing as universal matching bearing. Spindle bearing mainly used for applications where a high working speed and rotating accuracy are required, like machine tool, aircraft, medical, special equipment.
