6004-C-2Z FAG (6004-ZZ) Deep Grooved Ball Bearing Shielded 20x42x12

6004-C-2Z FAG (6004-ZZ) Deep Grooved Ball Bearing Shielded 20x42x12 . Also known as: 6004-ZZ, 6004-2Z

FAG Generation C Single Row Deep Groove Ball Bearings. Thanks to design modifications such as improved bearing kinematics, new seals and cages as well as refined manufacturing processes, deep grove ball bearings of Generation C have numerous advantages including lower noise levels and lower friction.

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 (2Z, ZZ) - Bearings fitted with steel shields and lubricated for life.
• Rubber Seals (2RS, 2RSR, 2HRS) - 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.
