This 55mm inch ball bearing is high quality and can take electric motor demands if needed.

Deep Groove Ball Bearings are the most common bearing type found in a wide variety of applications. Versatile and robust they are available in a wide range of sizes and options including seals, shields and special clearance for high speed applications. The main types are:

Open - Bearing without seals or shields, suitable for applications where lubricant will constantly flow through them i.e. gearboxes.

Metal Shields - Bearings fitted with steel shields and lubricated for life.

Rubber Seals - Bearings fitted with steel reinforced rubber contact seals which provide a better seal but add friction so are unsuitable for high speed applications, lubricated for life.
