5.1 Deep groove ball bearings in the structure of each ring has a cross section of both the equatorial circumference of the ball about one-third of long continuous groove type raceway. 5.2 Deep groove ball bearings are mainly used to bear radial load, but also bear certain axial load. 5.3 When the bearing radial clearance increases, with the nature of angular contact ball bearing can withstand both directions alternating axial load.

Because the lubricant is one kind sticks the thick gelatinous material, therefore lubrication film toughness is high, can withstand the big load, is not easy to drain, easy to seal, stuffing may maintain quite long period of time. Wave he bearing's attire fat quantity generally for bearing inner space volume 13~2/3. . Regarding these inconvenient increases the lubricant frequently the place, or these did not allow the lubricating oil outflow to send the pollution product the industry machinery

Ball track sound is a kind of stable and successional noise that is made by the circulation of bearing when the ball is rolling in the ball track. People will notice it only when the sound pressure level and express are loud. Actually sound power of the ball track is limited. The sound of high quality 6203 bearing is 25-27dB, The single row deep groove ball bearing has the typical model of this noise. It has the following features:1.noise and vibration are random

SF-2 boundary lubricated bearings plus: acid poly A with formaldehyde, with high wear resistance, bearing surface arrangement of the law must be fitted with a storage pit filled with grease, especially for high load low speed rotational motion, rolling motion, and often contain negative, the formation of lubrication is not easy to open and close the site, in the boundary lubrication conditions, without refueling for long-term use and maintenance,

Currently, the most widely used high-speed spindle bearings is hybrid ceramic ball bearings, which use rolling or hot isostatic pressing Si3N4 ceramic ball bearing ring remains rims. This bearing high standardization, low price, small changes in the machine tool, easy maintain, high-speed operation suitable for occasions. It's d · n values over 2.7 × 106. In order to increase bearing life,

1.spherical roller bearing 2.high speed, low noise 3.certifcate:ISO9001:2000 4.good quality and competitive price With the same center as the bearing, the spherically formed outer ring raceway can make self-alignment. Their rolling elements linearly come into cnotact with raceways of inner ring and outer ring. The bearings can take great radial load, suitable for heavy machinery used in mining, metallurgical, paper-making and construction etc.

A hardened , martensitic stainless steel, 440C is the standard choice for a wide range of military and commercial applications. 440C is suitable for applications which require corrosion resistance in a thermal range from room to mid-hot.300 Series Stainless Steel (316 & 303)In a semi-precision grade bearing, 300 series stainless steel can be chosen for improved corrosion resistance over 440C. These materials are not heat treated so load

The outer ring of the self-aligning roller bearing is a sohere,which takes the bearing senter as its center,there are two raceway on the inner ring,which have certain angle with the axes,and it has favorable self-alignment function.Mainly it can be subjected to radial load and the axial load from any direction.It can be used for the equipment of mining,metallurgy,paper mill and construction feature: 1. low revolutions2.resistant to impact and vibration
