SS 6902 ZZ/2RS stainless steel deep groove ball bearings

Selected Material System: The raceways are available in AISI 420 (martensitic, high hardness) or AISI 304 (austenitic, highly corrosive environments) stainless steel, providing excellent mechanical strength.

Precision Manufacturing Process: The rolling elements utilize G10 grade high-precision stainless steel balls, combined with optimized raceway geometry, significantly reducing rotational friction and operating noise, ensuring smooth operation at high speeds.

Optimized Structural Design: The 69 series ultra-thin bearing achieves maximum load capacity within a limited space; the deep groove raceway effectively withstands radial and bidirectional axial loads.

Flexible Sealing Options: ZZ metal dust caps (suitable for high speeds and high temperatures) and 2RS rubber seals (better dust and water resistance) effectively extend lubrication life and improve reliability in harsh environments.

Manufacturing Advantages: Solid stainless steel bars are machined, resulting in a denser and more uniform metal flow line on the raceways; end-to-end one-stop production with strict control over every manufacturing stage ensures consistent quality.

Flexible configuration options: materials can be selected according to corrosive environments, sealing methods can be selected according to speed and sealing requirements, industrial or food-grade grease can be selected, and non-standard processing is supported (such as grooving of the outer ring and V-groove processing of the inner ring).

Choosing SS 6902 stainless steel deep groove ball bearings means equipping your equipment with a key component that achieves the optimal balance between space efficiency and operational reliability. Its slim design directly saves axial and radial space, enabling more compact mechanical structures while ensuring low-noise and low-vibration operation at high speeds. Our manufacturing advantages ensure consistent quality from the source. The bearings are machined from solid stainless steel bars supplied by specialized steel mills, rather than tubular stock, resulting in a denser, more uniform metal flow line on the raceways. Our end-to-end production model, from materials to finished product, allows for strict control over every manufacturing step. We offer flexible configuration options to meet diverse operating conditions. You can choose different materials such as AISI 420 or 304 for corrosive environments, ZZ or 2RS seals for speed and sealing requirements, and industrial or food-grade grease. Furthermore, we support non-standard machining, such as grooved outer rings (for snap ring fixing) or V-grooved inner rings (for seals), supporting special designs.
