The core characteristic of the SKF 6305-2Z is its excellent versatility and protection.The two-sided pressed steel shields are fixed into the bearing outer ring with an interference fit,creating an effective labyrinth sealing structure that significantly blocks dust,dirt,and other solid contaminants while retaining the lubricant.Manufactured from high-quality chrome steel,the bearing undergoes precision machining and heat treatment to ensure dimensional stability and high load-carrying capacity.The cage,made from stamped steel,is robust and lightweight,suitable for high-speed operation.This bearing features low friction,low noise,and low vibration.It is simple to install,ready for use,and requires no additional sealing devices,greatly simplifying the surrounding design and reducing overall manufacturing and maintenance costs.

The SKF 6305-2Z conforms to ISO standard dimensions with precise geometrical tolerances.Its bore diameter is 25 mm,outer diameter is 62 mm,and width is 17 mm.The dynamic load rating is 22.0 kN,and the static load rating is 11.5 kN.The limiting speed is 13,000 r/min(under grease lubrication).The bearing is pre-filled with high-quality lithium-based grease,suitable for a common operating temperature range of-30°C to+110°C.The bearing radial internal clearance is the standard CN group,which balances operational temperature and preload requirements for most applications.Its radial internal clearance is strictly controlled before installation to ensure smooth operation.These specifications make it the preferred choice for standard industrial equipment like electric motors,gearboxes,and transmission shafts.
Due to its reliable sealing and versatility,the SKF 6305-2Z is widely used across various industrial sectors.It is a standard bearing in small and medium-sized electric motors(e.g.,fan motors,pump motors,appliance motors),effectively preventing carbon brush dust and environmental debris from entering.In the automotive sector,it is commonly used in alternators,air conditioning compressors,and idler pulleys.Furthermore,it is frequently found in conveyor rollers,agricultural machinery,and light industrial machinery(e.g.,food processing equipment,packaging machinery)for transmission purposes.Any application requiring protection against grease contamination/loss and operating in moderately dusty,medium-speed,and medium-load environments is a typical scenario for this bearing.
