SS 687 ZZ/2RS stainless steel deep groove ball bearings

Balanced design for specific operating conditions; multiple stainless steel materials (AISI420, AISI304, etc.) to balance mechanical strength and corrosion resistance; G10 grade high-precision steel balls with optimized raceway processing technology for low friction torque, low operating noise, and smooth high-speed rotation performance; thin structure to ensure sufficient load-bearing capacity and minimize radial installation space; deep groove ball structure to withstand radial loads and a certain amount of bidirectional axial loads; ZZ metal cap to effectively block larger particles and foreign objects, and 2RS rubber seal to provide a better dust and moisture barrier, extend grease life, and ensure long-term stable operation.

Choosing the SS 687 bearing is primarily due to its precise dimensional positioning and structural value. Its slim design, with an inner diameter of 7mm, an outer diameter of 14mm, and a width of 5mm, is a tailor-made solution for miniaturized equipment structures, providing stable and reliable rotational support within extremely limited space, significantly improving the compactness and integration of equipment designs. Our manufacturing advantages ensure the inherent quality of our products. Bearings are machined from solid stainless steel bars supplied by specialized steel mills, rather than using tubular stock, guaranteeing the density and consistency of the material structure from the outset. Our one-stop production model allows us to maintain strict control over the entire process from raw materials to finished products. We offer high configuration flexibility to meet diverse application needs. You can select the appropriate bearing ring material (such as AISI420 or AISI304) and seal type (ZZ or 2RS) based on specific corrosion resistance ratings, operating temperatures, and environmental requirements. Lubricants are also available in industrial and food-grade options. In addition, we support non-standard machining for the SS 687 model, such as slotting the outer ring (for snap ring fixing) or machining V-grooves on the inner ring (for mating with seals), to adapt to special installation and sealing requirements.
