608 bearing 6 saPlastic bearingid it is a deep groove ball bearings， 0 refers to a series of deep groove ball bearings， 8 represents the diameter size of 8 mm。608 the size of the bearing is 22 mm (diameter) of 7 mm (width) and 8 mm (inner diameter)。Sometimes， we write 608 prefer 8 x22x7mm said。Of course， if the customer has custom-made requirements， we can do it， too。
Bearing a total of 608 including a handful of the ball， two rings， a cage (nylon or stainless steel) and two seals。Sealing ring material can be metal or rubber seal。If you choose to metal seal， we can say them as 608 zz。If you select the rubber sealing ring， we can call them the 608-2 - rs。
In general， 608 material is chrome steel， but we can also provide some special 608 materials， including stainless steel and ceramic。
ABEC 1 grade skateboard bearing is precision grade of the lowest among all the skateboard bearing。But that doesn´t mean ABEC 1 levels of 608 zz can´t use。First of all， we should know what ABEC 1?It originated in the United States Bearing manufacturers association (ABMA) circular Bearing project Committee， hereinafter referred to as ABEC。
There are many references on our website ABEC 1 slide bearing parameter information， you can also use wikipedia to find relevant information。These parameters information data is very professional。
I believe that for the skateboard lovers， learning these will be a little difficult。As for ABEC 1 slide bearing， we concluded that it is in many occasions， to provide the most common bearing， it is not high requirement， so the price also is not very high。
As China´s economic development， the bearing industry has formed a larger economies of scale。But compared with the world´s industrial powers， China bearing industry there is a certain gap。In recent years， with the vigorous development of the economy， China´s bearing industry senior new ability to greatly enhance its capability of the supporting of the national economy， It has been able to produce more than 70000 specifications of various types of bearings， basic can satisfy the demands of national economy and national defense construction of form a complete set。
The development of the miniature bearing， was widely used in all walks， performance， life and reliability of demand is higher and higher， to the number of more and more。But the domestic is still a weak link in miniature， import it had to spend a lot of foreign exchange each year。
Home and of course some good miniature bearing enterprises， including Shanghai strong force bearing manufacturing co。， LTD。， production of miniature bearing production level in the domestic leading level， can satisfy the user of the miniature bearing is high precision， low noise， long life demand of the product。
Miniature ball bearing is suitable for high speed rotation， low friction torque， low vibration， low noise requirements of products， such as office equipment， micro motor， soft， pressure rotor， dental drill， hard disk drive motor， stepping motor， VCR magnetic drum， toys， model， computer fan， etc。， all kinds of industrial equipment in recent years， small rotary motor of micro miniaturization， lightweight and thin wall type tended to increase， stimulate the demand of miniature bearing up。
