The material for choice is chrome steel (Gcr15/SAE52100) and stainless steel (9Cr18/AISI440).  The grade is from ABEC-1, ABEC-3,ABEC-5, ABEC-7 at your request. Our thrust ball bearings and miniature ball bearings are well known for low noise, high speed, long life and competitive price etc. Miniature Deep Groove Ball Bearings are widely used in the fields of precision equipment, home appliance, power tool, medical machinery, fishing reel, motor and RC hobby etc.

TPI roller bearing company cooperates with the best grease manufacturers in the world which allows us to suggest and apply the best lubricating selection for our customers.

Bearing life is usually expressed as the number of hours an individual bearing will operate before material fatigue develops on either the raceways or the rolling element. The usual life rating for industrial applications is called “L10” life. The L10 life is the number of hours which that 90% of bearings will survive； or, conversely, 10% of bearings will have failed in the L10 number of service hours. One thing to be noticed that, roller bearing has different factor when it comes to bearing life calculation.

Cylindrical roller bearings with tapered bores are usually used to allow easier adjustment of internal clearance. When the radial internal clearance becomes negative, the cylindrical roller bearings are preloaded. Generally, cylindrical roller bearings for the front end (fixed end) of the spindle are preloaded during operating. Bearing for the rear end (free end) are adjusted to produce a slight clearance during operating. The amount of radial internal clearance after mounted is based on several factors such as rotating speed, load, bearing size, required rigidity, etc.

1) Less than 45KGS,we will send by express.( Door to Door.Convenient ) 2)Between 45-200KGS,we will send by air transport.( Fastest and Safest,but Expensive ) 3)More than 200KGS,we will send by sea.( Cheapest,but along time )
