Engineered as part of the robust 6300 medium-duty series, the 6307-2RZ is a high-performance single-row deep groove ball bearing featuring advanced non-contact rubber seals. With a 35 mm bore, an 80 mm outer diameter, and a substantial 21 mm width, this component is built to handle significant radial and axial loads. The defining feature of the "2RZ" designation is its specialized sealing technology: the rubber lips closely approach the inner ring without making physical contact. This innovative design offers a superior middle ground, delivering far better dust and moisture resistance than standard metal shields (ZZ), while completely avoiding the friction, heat generation, and speed limitations caused by traditional contact seals (2RS).
