Product Description

The W624-2Z Bearing is a precision-engineered Double Shielded Ball Bearing designed for compact applications requiring reliable performance in confined spaces. As a Miniature Deep Groove Bearing, it features a 4 mm inner diameter, 13 mm outer diameter, and 5 mm width, optimized for low-noise operation and moderate radial loads up to 1.3 kN dynamically. Constructed with chrome steel rings and nylon retainers, it operates within a temperature range of -30°C to +120°C. The dual shielded design provides effective contamination protection while maintaining smooth rotation at speeds up to 18,000 rpm. Ideal for miniature motors, medical devices, and precision instruments, this bearing combines durability with space efficiency, though its small size limits maximum load capacity compared to larger counterparts. No lubrication is required during service life due to pre-greased shields.
