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.

Deep groove ball bearings are the most simple from the standpoint of design and construction. Their use is very widespread.

Although it is primarily a radial bearing, it is capable of handling moderate thrust loads from either direction and operating at relatively high speeds.

The bearing rings have symmetrical, deep-grooved raceways without filling slots or a counter-bore. The raceways are precision ground to conform closely to ball curvature, consistent with minimum friction, maximum capacity, and practical manufacturing techniques. The balls are selected for uniformity to ensure optimum internal load distribution.

The bearing uses the maximum number of balls which can be inserted between the raceways by eccentrically displacing the inner and outer rings. 

the identification of the bearing

For the low cost pursue, some small manufacturers print the black stamps on the bearing to identify models and manufacturers, with some very simple equipments, electro etching solutions, and very simple templates. Because of the low cost, it is used by some inferior products.

Formal manufacturers use laser engraving. The stamps are deep, have significant dents with hand touch, good-looking, with no breakpoints, and are never disappeared. This obviously improves the bearing grade.

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.
