Good Quality Shandong Made 1312atn Conveyor Roller Bearing with Low Price and High Precision

Shandong XinKaite Bearing Co. Ltd. is located in Yandian of Liaocheng in mainland China. Our company concentrates on manufacturing conveying machinery bearings, including conveyor bearing, KA bearing, deep groove ball bearing, and also conveyor roller, conveyor 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.

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.

The ring is the main part and the important part of the conveyor roller bearing. Best conveyor 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 conveyor roller bearing must be made of bearing steel, named "High Carbon Chromium Bearing Steel (Fully quenched class) GCr15". At present the standard hardness of conveyor 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 conveyor roller bearing is to see if its hardness is over 60 degree, because only bearing steel can get over this degree.
 
Grease selection of conveyor 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.
 
FAQ:
 
I couldn't find a design to fit my application in your catalog. Can you help me design a bearing?

Yes, technical expertise is available to assist you with engineering design for custom products. Available options include, but are not limited to, custom rings, retainers, balls, shields, lubricants, and packaging. We look forward to working with you to satisfy your rotary motion requirements.

What causes bearing noise?

Bearing noise is a function of both the bearing and the way it is used. Some external factors that affect bearing noise include lubricant type, excessive bearing load, and improper installation. Once the abnormal noise occurred, you can contact our engineers, we will help you find the reasons and provide the appropriate solutions.

What is the difference between using a shield or a seal as a ball bearing closure?

Shields or seals are often installed to retain lubricant and to prevent contamination from entering the bearing. While a shield contacts the outer ring and does not come in contact with the inner ring, the seal generally comes in contact with both the inner and outer rings. Torque or drag is lower with a shield than with a seal. Alternately, the seal provides a higher degree of protection from contamination. Shields and seals are available in a variety of materials and configurations.

XKTE developed a serious of sealing methods for different applications. Please contact a XKTE engineer for technical assistance with any special requirements.
