SKF Kullager, 8 mm ID, 19 mm UT, Löpring bredd 6 mm

When there's a need for speed, use this single-row ball bearing from SKF to support your machines and motors. It has a deep-groove raceway to accommodate radial and axial loads in both directions while reducing friction and vibration. This means it can continuously turn at 43,000rpm without any problems. Shielding on both sides keeps the rolling parts lubricated and stops dirt from getting inside, so you can expect a long service life with little maintenance.

• Simple cylindrical design makes it easy to mount

• Pumps and fans

Not at all. This ball bearing has an inside diameter of 8mm and an outside diameter of 19mm, so you can slot it into small appliances, power tools and motors. A race width of 6mm means there's no trouble squeezing onto a shaft in setups where space is at a premium.
