Product Description

The 634-2Z Bearing is a precision Double Shielded Ball Bearing with a compact 4mm ID, designed for applications requiring reliable rotational performance in constrained spaces. Featuring dual shielded protection, it effectively prevents contamination while maintaining low friction. This bearing supports radial loads up to 130N and axial loads up to 50N, operating within a temperature range of -20°C to +120°C. Ideal for small motors, instrumentation, and precision machinery, its chrome steel construction ensures durability and high-speed compatibility (up to 28,000 RPM). Key advantages include reduced maintenance needs and extended service life, though it lacks sealing for heavy particulate environments. The compact 4mm bore suits miniature assemblies, while its lightweight design enhances efficiency in automation and electronics industries.
