Product Description

The SKF W 619/4-2Z Bearing is a 2Z shielded ball bearing designed for precision applications requiring compact dimensions and reliable performance. This miniature bearing features a 4 mm bore, 11 mm outer diameter, and 3 mm width, with dual metal shields (2Z) providing effective protection against contaminants while retaining lubrication. It operates within a temperature range of -30°C to +120°C and is pre-lubricated with grease for low-noise, low-torque rotation, making it ideal for small electric motors, medical devices, or precision instruments. Constructed from chrome steel, the W 619/4-2Z supports moderate radial and axial loads, with a maximum speed rating of 36,000 rpm (oil-lubricated) or 28,000 rpm (grease-lubricated). Its compact design and shielded construction ensure durability in dusty environments, though frequent relubrication is not possible due to the sealed design. This bearing excels in industrial automation, robotics, and electronics where space constraints and contamination resistance are critical.
