SS 609 ZZ/2RS stainless steel deep groove ball bearings

Excellent Dynamic Load Capacity:  For the high-frequency impacts in power tools and gear transmissions, we have optimized the inner and outer rings of the SS 609 with increased thickness. Combined with the high hardness of AISI 420 martensitic stainless steel (HRC 58-60), it effectively resists deformation and wear under high torque, offering a lifespan far exceeding that of ordinary carbon steel bearings.

EMQ Motor-Grade Quiet Standard: The SS 609 is commonly used inside motors, where noise control is crucial. Our entire product line adheres to the Z2V2 quiet standard, passing 100% noise/vibration testing. Combined with G10 grade steel balls, this ensures your motor runs with only the sound of airflow, without any extraneous noise.

The Nemesis of Dust and Debris: In cutting tools or gear transmissions, fine particles are bearing killers.
2RS (Double Lip Seal): Uses high-elasticity NBR or FKM rubber, tightly fitting the inner ring to effectively block carbon brush powder and metal debris from entering the raceway.
ZZ (Metal Shield): Suitable for high-temperature or debris-free environments, providing a zero-friction high-speed experience.

High-Temperature Grease Customization:  Considering the heat characteristics of motors, we offer high-temperature lubricating grease with a dropping point exceeding 200°C, preventing grease evaporation and ensuring the bearing remains well-lubricated even under prolonged full-load conditions.

"Optimized specifically for motors and transmissions." We understand the critical importance of coaxial alignment when assembling 9mm bearings. Therefore, our SS 609 bearings are manufactured with strictly controlled inner diameter tolerances to ensure the perfect interference or clearance fit with the motor shaft – preventing noise caused by excessive tightness and avoiding looseness that could lead to bearing runout. For customers exporting to Europe and the Americas, we also provide material certifications compliant with RoHS/REACH environmental standards, helping you expand into overseas markets with confidence.
