Ball and roller bearings are available with different types of shields and seals These are commonly referred to as closures Closures can extend bearing life by preventing contaminants from reaching the critical surfaces inside the bearing and they help retain the lubricant in the bearing

The main purpose of lubricants in rolling bearing is to reduce friction and wear of each element Deep groove ball bearing components ( ZZ type ) Notes: The above bearing construction drawing only lists one type of inner ring construction (V-groove) which is applied usually in sealed bearings

QIBR 6913 ZZ bearing 65*90*13 mm deep groove ball

The service life of the QIBR 6913 ZZ bearing is not only related to its own quality but also related to the installation method load speed temperature and daily working hours If there is any problem in the use of the QIBR 6913 ZZ bearing please provide us with the above information in time so that our technicians can make an accurate and

Bearing Fatigue Life The fatigue life of a guide wheel bearing is defined by the number of revolutions the bearing will operate before the first signs of fatigue occur The L 10 life is the basic rating life in hours that 90% of a sufficiently large group of apparently identical bearings will operate before the first signs of

When you want to avoid fatigue failures of the bearing before your application reaches its desired lifetime you can use a statistical approach to determine the bearing size The rating life L 10 is the fatigue life that 90% of a sufficiently large group of identical bearings operating under identical conditions can be expected to attain or exceed

2017-11-24The life of a given bearing is a nonlinear function of the applied load For a ball bearing it is related to load to the 3 00 power (i e load x load x load) For roller and needle bearings it is the 3 33 power That means that a relatively small increase in bearing load can cause a dramatic reduction in bearing life

"The shelf life of open bearings is based on the continuing ability of the corrosion inhibitor to protect the bearing surfaces during storage Although open bearings older than eight years based on the package date may be acceptable for use we do not sell nor restock bearings of that age " McDermott says

Bearing Rating Life Calculation "Rating life" is the bearing life calculated for 90% reliability This is the amount of time that a group of apparently identical bearings will complete or exceed before the formation of a fatigue spall The basic formula for calculating bearing L 10 rating life is: where: C = Dynamic Capacity (dN or Lbs)

2017-11-24The life of a given bearing is a nonlinear function of the applied load For a ball bearing it is related to load to the 3 00 power (i e load x load x load) For roller and needle bearings it is the 3 33 power That means that a relatively small increase in bearing load can cause a dramatic reduction in bearing life

Therefore the two main criteria that can be used for determining appropriate bearing size are: Size selection based on rating life: This is based on the required bearing life taking into account the possible effects of rolling contact fatigue and requires calculation of the basic rating life L 10 or QIBR rating life L 10m for the bearing Size selection based on static load: This is based
