602-2RS Sealed Miniature Deep Groove Ball Bearing for Moisture-Resistant Applications | 2×7×3.5 mm

The 602-2RS is a Double Rubber-Sealed Miniature Deep Groove Ball Bearing engineered for compact mechanisms requiring reliable protection against moisture, dust, and fine particulate contamination. With two synthetic rubber contact seals (2RS) on both sides, this bearing provides excellent sealing performance while retaining lubrication and preventing ingress of contaminants in challenging environments. Featuring a 2mm bore and ultra-compact cross-section, it is ideal for precision instruments, small electric motors, and medical devices where space is severely limited and operational cleanliness is critical .



602-2RS Deep Groove Ball Bearing 2×7×3.5 mm | ISO 69 Series – Extra Light | Double Rubber Sealed

This versatile sealed bearing is designed for smooth and reliable operation at speeds up to 60,000 r/min (Oil). It handles light radial loads and accommodates minimal axial loads from either direction, making the 602-2RS an excellent sealed solution for miniature drives, laboratory instruments, and mechanisms where protection against moisture and fine particles is essential for long-term performance.

Key Performance Features

01. Precision-Matched for Smooth & Quiet Operation

Available with precision grades up to ABEC 5 (P5), the 602-2RS features precision-machined raceways and high-grade chrome steel balls to ensure low noise, minimal vibration, and consistent performance in high-speed and noise-sensitive applications.

02. Ultra-Compact & Lightweight Design

Built to extra-light series dimensions (2×7×3.5 mm) with a weight of approximately 0.6 grams, this bearing maximizes space efficiency without sacrificing performance . Its slim profile supports light radial loads, making it suitable for highly constrained assemblies in miniature equipment.

03. Enhanced Rubber Seal Protection

Double rubber contact seals (2RS) provide excellent defense against moisture, dust, and fine contaminants while maintaining stable internal lubrication. The flexible sealing lips maintain light contact with the inner ring, offering reliable protection in humid or dirty environments where metal shields would be insufficient.
