C3 Clearance - Increased internal clearance between the rolling elements and raceways for high temperature and high speed applications
Deep Groove Ball Bearings are the most 30x55x13 Bearing 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 (ZZ, 2Z) - Bearings fitted with steel shields and lubricated for life.
Rubber Seals (2RS, 2RSR, 2RSH) - Bearings fitted with NSK 25tac62b Bearing steel reinforced rubber contact seals which provide a better seal but add friction so are unsuitable for high speed applications, lubricated for life.
