SS 688 ZZ/2RS stainless steel deep groove ball bearings

A balanced material system, precision manufacturing, and compact design adapted to micro-devices; multiple stainless steel materials achieve the best balance between corrosion resistance and mechanical strength; G10 grade high-precision steel balls and optimized groove design ensure low frictional torque, low operating noise, and smooth high-speed rotation performance; thin-section deep groove ball structure effectively withstands radial loads and a certain amount of bidirectional axial loads in a small size; ZZ type metal dust cover or 2RS type rubber seal effectively prevents contaminant intrusion, extends grease life, and provides reliable protection.

First, we select bearings with precise dimensional value. Their 8mm inner diameter, 16mm outer diameter, and mere 5mm width represent typical miniature thin-film bearing designs, providing stable, low-friction rotational support in the most compact mechanical structures, significantly improving equipment space utilization and design flexibility.

Our manufacturing advantages ensure reliability: starting with machining solid stainless steel bars sourced from specialized steel mills, we rigorously control every step from material to finished product through a one-stop production model, guaranteeing dimensional accuracy and performance consistency.

We offer flexible configurations tailored to your specific operating conditions: you can choose different stainless steel materials based on corrosion resistance requirements; select ZZ or 2RS seals based on speed and sealing requirements; and choose industrial-grade or food-grade grease. Furthermore, we support non-standard machining such as outer ring slotting (for snap ring mounting) or inner ring V-groove to meet special positioning and installation needs.
