Part of the robust 63 dimension series, the 6307-2Z ball bearing is engineered with a thicker cross-section to accommodate heavier load requirements than its 62 series counterparts. Featuring boundary dimensions of 35 mm (bore), 80 mm (outer diameter), and 21 mm (width), this bearing is enclosed on both sides with non-contact metal shields (-2Z or ZZ). This shielded architecture effectively prevents the ingress of dust, dirt, and metallic debris while retaining the internal lubricant, making it an ideal maintenance-free solution for industrial environments.
