Shandong XinKaite Bearing Co. Ltd. is located in Yandian of Liaocheng in mainlandChina. Our company concentrates on manufacturing conveying machinery bearings, including conveyor idler bearing, KA bearing, spherical roller bearing, deep groove ball bearing, and also idler roller, idler roller accessories, and 0 class bearing. We enjoy high states in the industry because of our products' high quality and low price, and professional stability.
Started in 2006, formerly Shandong Guan County XinKai bearing Co. Ltd., our company relies on the Yandian professional bearing market, pushes the business to market domestic and abroad. And there are many long-term fixed partners of ours within the areas centered by conveying machinery bearing industry. With our company's gradually growing, from the rough to the bearing, we set up a one-stop production line, with a daily output of million sets. Thus to make our products have a very high market competitiveness.
Our company is in line with the goal of zero defect products, continuously introducing professional production equipments and sound detecting instruments, and constantly improving our products' quality. The strict inspection before leaving the factory, with double test of artificial and instrument, ensures that each batch of products achieve a unified standard.
To be the first class, to do the best quality, to make users satisfied, to ensure customers relieved, are our enterprise purposes. To reduce price with strength and to develop enterprises with sincerity are our management ideas. Welcome conveying machinery manufacturers' contact from all over the world, and become our partners.
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.
The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.
Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.

The use of bearing retainer
Bearing retainer selection is very important. Because once too much dust stuck into the bearing, the retainer will be first worn. If the bearing retainer is broken, the bearing will be directly broken. Imported bearings use big rivets to thicken retainers. XKTE bearing is completely in accordance with the process of imported production, so each piece of ours is made to a high quality, and guaranteed to operate for thirty thousand hours.
Selection of nylon retainer
Nylon retainer bearing is often used in the mine. Nylon retainer has better anti-stuck performance and wider range of temperature than iron retainer. In the underground its anti-static performance is also better. To get safety certificate for coal mining products must use nylon retainer KA bearing. The selection of nylon retainer is crucial to KA idler roller bearing, while the material of nylon retainer must be pure and has enough toughness and strength, because the retainer will get very soft if it is made of bad material or mixed material, thus to make no anti-stuck performance within the bearing.
The ring is the main part and the important part of the idler roller bearing. Best idler roller bearing has deep groove ball, and large clearance. But deep groove doesn't mean to dig the channel with a simple way of enlarge the steel ball. The thickness of the bearing is certain, so to get the ball big and the groove deep will shorten service life. Our XKTE bearing uses way of thickening ring to get the standard of deep groove and large clearance, improves the anti-stuck performance, and effectively increases the service life.
Bearing material and hardness
Good idler roller bearing must be made of bearing steel, named "High Carbon Chromium Bearing Steel (Fully quenched class) GCr15". At present the standard hardness of idler roller bearing is 60-65 degree, while hardness of ring is 61-62 degree, and ball is 64-65 degree.
The simple way to identify idler roller bearing is to see if its hardness is over 60 degree, because only bearing steel can get over this degree.
Grease selection of roller bearing
Many customers ignore this most critical point. The thirty-thousands-hours operation is a very long term. This has to be guaranteed by enough quality and quantity grease. And this should also be taken into account of working in different seasons.
Special note: please choose special high temperature grease if working environment is over 120 °C for long time or low temperature grease if it below -20 °C.
