Roller bearing in the operation of the process will inevitably damage occurred, if abnormal heat, vibration and noise increase of the phenomenon of sudden, that Roller bearing may have been damaged should be checked in time and analyze causes. Common failure modes are:  A, indentation    When the outside world durum substances into the bearing, and pressure in between the rolling element and raceway, make rolling surface indentation. In addition,

Needle Roller Bearing(NA, RNA, RNA69, NKI, NKIS, NK) FBX needle bearing can take big radial load. Such a bearing has two kinds, with and without inner ring which is made up of a machined outer ring, a needle and cage assemblies and a separable inner ring. Main structure frame: NK- needle bearing without inner ring, light series NKI- needle bearing, light series NKS- needle bearing without inner ring, heavy series NKIS- needle bearing, heavy series

**SI2N4 **ZrO2 **SSIC Si3N4 (Silicon Nitride) Ceramic Bearings The ultimate hub has to have the ultimate bearings. Silicon Nitride (Si3N4) ceramic bearings are 30% lighter than steel and 40% stronger. So finely balanced, they have an incredible maximum spin rating of 300, 000 rpm under load. Manufactured in matched sets of 15 balls per cartridge, they exhibit variance in size and sphericity of LESS than 2 millionths of an inch among the entire bearing set.

Precision / Miniature Bearings, Key Specifications/Special Features: The range of model number: Miniature bearings Inner diameter 1mm -10mm, 3/32" - 1/2" and flanged types Thin type ball bearings 6700-6707, 6800-6818, 6900-6920, 16000-16028 with open, z, zz, 2RS Deep groove ball bearings (with open, z, zz, 2RS) 6000-6030, 6200-6228, 6300-6330, 6403-6418, inch series: R, RLS, RM, 1600 series Special high precision ball bearings for car Alternator & starters,

 Recommended Applications:  F for high temperature environment, precision bearings, motor bearings, miniature bearings lubricated.  G for all kinds of high-speed bearings, high-speed long-life gyro motors, high-speed grinder and other high-speed instrumentation and mechanical bearing lubrication.   H Organization smooth, fine fibers with high cleanliness, can inhibit the bearings during operation of the different sound,
 

Bearing rust process commonly used method among the following: 1. Dipping concentrated solution of sodium nitriteThe product after washing, immersed with 15% -20%, 0.6% sodium nitrite and sodium carbonate solution, then it stacked up. In this way the rust of a short, generally only 7-14 days to maintain, but also in the rainy season, wet weather, keeping only 2-3 days to be reprocessed, it takes labor and money.

One of imports properly installed precision bearings Installation of bearing products for imports for one-off installation up and pay attention to something, and if not installed, then the import will not long bearing life. So, we need the import the import bearings installed, you should know to install their own methods of imported bearings, so as to ensure that imported bearing damage during installation. Following me to introduce comprehensive check the accuracy of imports bearing installation method:

1: How to improve the bearing accuracy:1, the precision spindle bearings and can not meet the requirements, after the bold and the fabrication journal roller to replace the inner ring and ball were measured waxy close to a size for every three groups ball close to 120 ° intervals to take separately, due to a decrease of the surface of a re-processing, but also reduces the surface with a weight, while improving the axial stiffness of a bearing system,
