The 6211-2RS and 6211-ZZ is a 55mm ball bearing that is found in many applications. The 6211-2RS ball bearing has two contact rubber seals one on each side of the ball bearing. The 6211-ZZ ball bearing has two non-contact metal shields one on each side of the ball bearing. If your application requires a 6211 ball bearing with only one seal or 55x100x21 Bearing shield you can get this ball bearing and take one of the shields or seals off. 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 SKF 6207 Bearing steel reinforced rubber contact seals which provide a better seal but add friction so are unsuitable for high speed applications, lubricated for life.
