Ceramic Section Bearing 689 17x9x5mm with Z1 Z2 Z3 Vibration Grades and ISO9001 Certification

High-performance ceramic section bearing model 689 with dimensions 17×9×5 mm, designed for smooth operation and vibration control with precision grades Z1, Z2, and Z3.

Zirconia all-ceramic bearings feature anti-magnetic insulation, excellent wear and corrosion resistance, oil-free self-lubrication, and high temperature/cold tolerance. Maintains dimensional stability within 100℃ to 600℃ temperature range. Suitable for harsh environments including strong acids, strong alkalis, inorganic/organic salts, and seawater applications.

Silicon nitride ceramic bearings offer diamagnetic electrical insulation, superior wear and corrosion resistance, self-lubrication, and exceptional high/low temperature performance. Capable of handling higher speeds and loads than zirconia bearings, with operating temperatures from 100℃ to 800℃. Available in precision grades up to P4 for high-speed, high-accuracy applications.

Hybrid ceramic ball bearings combine chrome steel or stainless steel rings with ceramic balls (ZrO2, Si3N4, or SiC). Benefits include low density, high hardness, low friction coefficient, anti-magnetic properties, wear resistance, self-lubrication, and excellent rigidity. Achieve 1.5x higher speeds and 2-3x longer service life compared to standard steel bearings.
