The EZO SS6406ZZ is a high-performance corrosion-resistant stainless steel deep groove ball bearing with double metal shield design, professionally produced by EZO for high cleanliness, humid and corrosive working environments. As a classic EZO stainless steel bearing, the SS6406ZZ features compact structure, low noise operation, excellent anti-rust performance and stable high-speed adaptability, serving as a core general-purpose precision bearing for light and medium industrial transmission equipment.
Complying with ISO and ABMA industrial standards, the standardized dimensional parameters are accurate and reliable: inner bore 30 mm, outer diameter 90 mm, overall width 23 mm, minimum mounting chamfer 1.5 mm, with standard ABEC-1 tolerance grade and optimized internal clearance for universal assembly.
All main load-bearing parts adopt premium anti-corrosion materials. Inner ring, outer ring and steel balls are made of AISI 440C martensitic stainless steel, with heat-treated hardness reaching HRC 58–62, featuring outstanding wear resistance, oxidation resistance and weak acid corrosion resistance. The precision pressed steel cage ensures uniform ball separation and smooth rotation; double ZZ metal shields effectively block dust, moisture and granular impurities to extend service cycle.
Its core manufacturing processes include precision stamping and forging, high-precision turning, integral vacuum heat treatment, raceway fine grinding and ball superfinishing. Strict dimensional screening and surface treatment eliminate residual stress, reduce running friction, guarantee low noise output and enhance overall mechanical stability of the EZO SS6406ZZ bearing.
Calculated in strict accordance with ISO 281 bearing life standard, the L10 theoretical service life reaches over 20,000 hours under standard load and clean lubrication. Operating speed, load intensity, environmental humidity, lubrication status and installation precision are the key factors affecting long-term service performance.
Widely applied in food machinery, medical equipment, electronic automation, packaging equipment, light industrial machinery and marine auxiliary devices, this EZO deep groove ball bearing is favored for its stainless steel corrosion resistance and fully sealed protective structure, perfectly adapting to moist and harsh light-load operating conditions.
Daily maintenance adopts food-grade or general NLGI 2 lithium grease, with 30%–35% internal cavity filling volume; regular inspection and supplementary lubrication are required every 400 working hours. Keep matching surfaces dry and clean, regularly check running noise and temperature, and replace timely if corrosion or rotation jamming occurs.
Before installation, remove burrs and dirt on shafts and housings. Adopt soft pressing installation to avoid violent impact, control coaxiality deviation within 0.05 mm, and implement standardized fastening torque. Conduct short no-load trial operation after installation to confirm flexible rotation and qualified assembly effect.
