Compared with other bearings, deep groove ball bearing has smaller friction coefficient and higher limiting rotate speed, it is more durable and universal with low noise and is easier to install. And the lubrication grease is sealed in the deep groove ball bearing. The sealed deep groove ball bearing could keep excellent balance between the friction and movement with high quality lubrication grease.

We are a manufacture specialized in producing conveyor roller bearing. bearings also have a clearance value. This provides the bearing room for expansion between the bearing races and will add a small amount of play between the two rings. large clearance C3/C4 usually used in mining machine.

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.

Reference:

Lubrication has a very important effect on the lifetime of the conveyor roller bearing.

1. How to select the lubrication grease?

Here we simply introduce the way to select the lubrication grease for you. The lubrication grease is made of base oil, thickener and additive, it has great difference of feature for different types of lubrication greases, and they call different rotate speed, so we must notice that during the selection.

The feature of lubrication is maimly determained by the base oil. Generally speaking, the base oil of low viscosity is used in the environment of low temprature and high speed, while the high viscosity in the environment of high temprature and high load. The water tolerance of thickener determines the water tolerance of the lubrication grease. In principle, different types of lubrication greases cannot be mixed. And for more, it would have different effects on the conveyor roller bearing for using different additives even the thickener is same.

2. Is it necessary to wash the conveyor roller bearing before the instalation?

The conveyor roller bearing is smeared with slushing oil on its surface, we must wash it with clean petrol or kerosene, and then smear clean lubrication grease to use it. It has a great effect on the lifetime and noise of the conveyor roller bearing that whether the component is clean. But the all-sealed conveyor roller bearing does not need to be washed and add oil.

3. How to instal and remove the conveyor roller bearing?

We could not knock the surface of the conveyor roller bearing directly while instalation. We should do it with proffesional installing tools to make the conveyor roller bearing holding uniform pressure, it will be more smooth for the instalation if the surface of component is smeared with lubrication grease. Or we can put the conveyor roller bearing into the mineral oil to heat it to 80-90 degrees, and then instal it immediately. We must donot make the temprature exceed 100 degrees.

If you get into trouble while removing the conveyor roller bearing, we suggest you put hot oil onto the inner ring of it, that would make the inner ring swell.

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.
