Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread.
In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.
For big deep groove ball bearings, machined brass cages are used.
Machined cages are also used for high speed applications.
Types
Basic type; With snap ring groove on the outer ring (-N); With one shield (-Z) on one side or two shields (-2Z) on both sides; With one seal (-RS) on one side or two seals (-2RS) on both sides.
All of Our products are made of Chrome Steel GCr15, with grinding groove and superfinishing technology.
Application
Mining machine, conveyor machine, Engineering Machinery, Agricultural Machinery, Construction Machinery, textile, chemical, auto motor, Transportation Vehicles, General industrial Equipment, etc.
Catalog of Deep groove ball bearing
Professional brings quality, detail creates success
XKTE bearing's most fundamental difference is:
The other manufacturers make products considering the price cheap, but we make products considering the service life. Each of the idler roller bearings we produce is fully implemented in the national standard. XKTE bearings exist for their quality and brand. You can deny our price, but you can never find out our products' defects in quality. XKTE conveying machinery bearing, a big brand, is worthy of your trust.
First, the identification of the bearing
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.
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, andball 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.
Reference:
The meaning of idler roller bearing, bearing for Conveyor support roller
If you have used the idler roller bearing, you may know how to use it and the environment where it is used. But if you want to make the idler roller bearing perform perfectly, you need to know more and deeply about it.
The idler roller bearing could be easily seen by its name that it is the certain combination of idler roller and bearing, if you want to know about the idler roller bearing, you should know about deep groove ball bearing first. The idler roller bearing is mainly used on belt conveyor and rubber belt conveyor, which plays a role of decreasing the friction among the components to make the machinery work better. We could produce the idler roller bearing with different clearances according to the user´s different requirements, and adjust the price.
Idler roller is the important part of all types of belt conveyor, it strongly holds the cargos and decreases the friction between cargos and belts. The idler roller could be classified as sulciform idler roller, concavo-plane idler roller, aligning idler roller and buffering idler roller. The sulciform idler roller is used to convey granular materialsl; aligning idler roller is used to adjust transverse location of the belt to prevent it from running deflected; buffering idler roller is used to decrease the shock to the belts.
As known, the value of belt is about 30 percent of the whole machine´s value, so it is important to prolong the lifetime of belt. Though the idler roller is small component which has simple structure, it is dear with good quality.
The idler roller bearing plays an important role in daily use. In conclusion, we could assess the quality of the idler roller bearing as these aspects: feature of waterproof, load ability, shock resistance, feature of dustproof, lifetime and so on.

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.
