SS 689 ZZ/2RS stainless steel deep groove ball bearings

Balanced material properties, precision manufacturing, and compact design; a variety of stainless steel options to ensure mechanical strength and provide flexibility in corrosive environments; G10 grade high-precision steel balls with optimized raceway machining for low friction torque, low operating noise, and smooth rotation; a thin profile reduces radial cross-section and saves axial installation space; deep groove ball design can withstand radial loads and a certain amount of bidirectional axial loads simultaneously; metal dust caps or rubber seals prevent contaminant intrusion, maintain grease cleanliness, and extend maintenance intervals.

Choosing the SS 689 bearing is primarily about its precise dimensional value and structural efficiency. Its 9 mm inner diameter and 5 mm width combination exemplifies the 68 series' slim design philosophy, maximizing space savings for compact equipment structures such as automation modules and precision instruments without sacrificing load-bearing capacity, providing a stable and space-saving rotary support solution. Secondly, our manufacturing advantages ensure product reliability. Bearings are machined from solid stainless steel bars supplied by specialized steel mills, with strict control over every step from material to finished product through a one-stop production model, guaranteeing dimensional accuracy and batch consistency. Thirdly, we offer flexible configuration options for this model, including mainstream AISI 420 or more demanding AISI 304 materials, industrial or food-grade grease, and metal dust caps or rubber seals to meet the protection and compliance requirements of different operating conditions. Furthermore, we support non-standard machining services, such as outer ring grooving (for snap ring positioning) or inner ring V-groove machining (for seal mating), enhancing its adaptability to specific mechanical designs.
