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.

The most important in the running of the conveyor is the idler roller. And the most important part of the idler roller is bearing. That is to say the selection of bearings is the top priority of the idler roller accessories.

Let me share with you, about what the details of the processing does a good idler roller bearing have got. How to identify idler roller bearing?

First, 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.

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.
