SKF 626 ZTN9/LT Deep Groove Ball Bearing 6x19x6

Overview

The SKF 626 ZTN9/LT is a single row deep groove ball bearing designed for compact, high-speed applications operating in low-temperature environments. It features a single non-contact metal shield (Z), a glass fibre reinforced polyamide TN9 cage, and is factory-filled with SKF LT low-temperature grease. This configuration provides low running torque, reliable lubrication at sub-zero temperatures and effective protection against airborne contaminants.

Industrial Applications

The bearing is widely used in refrigeration equipment, cold storage conveyors, electric motors, instrumentation, laboratory equipment, compact gearboxes, HVAC systems, food processing machinery, packaging equipment and OEM assemblies operating in cold environments where low-temperature lubrication is required.

Construction

The 626 ZTN9/LT incorporates precision-ground deep raceways with a single row of hardened steel balls. The Z metal shield protects one side of the bearing without contacting the inner ring, minimizing friction while retaining lubricant. The TN9 cage, manufactured from glass fibre reinforced polyamide PA66, reduces weight, lowers noise and improves high-speed performance. The bearing is pre-filled with SKF LT grease, formulated for reliable operation at low temperatures.

Material

The inner ring, outer ring and rolling elements are manufactured from premium through-hardened bearing steel with excellent fatigue strength and wear resistance. The TN9 polyamide cage provides low inertia and smooth ball guidance, while the SKF LT grease maintains lubrication at temperatures down to approximately -50°C.
