Deep groove ball bearing, or single rowradial, ball bearings, It usually consist of a pair of rings, a retainer, asingle row of steel balls. Its structure is simple, easy to use, non-separable,It is the most widely used type of bearing. This type of bearing is mainly usedto bear radial load, but it can also bear a certain amount of axial load ineither direction.

We are a manufacture specialized in producingconveyor roller bearing. bearings also have a clearance value. Thisprovides the bearing room for expansion between the bearing races and will adda small amount of play between the two rings. large clearance C3/C4 usuallyused in mining machine.

Professional brings quality, detail createssuccess

XKTE bearing's most fundamental differenceis:

The other manufacturers make productsconsidering the price cheap, but we make products considering the service life.Each of the conveyor idler bearings we produce is fully implemented in thenational standard. XKTE bearings exist for their quality and brand. You candeny 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 theconveyor is the idler roller. And the most important part of the idler rolleris bearing. That is to say the selection of bearings is the top priority of theidler roller accessories.

Let me share with you, about what thedetails of the processing does a good conveyor idler bearing have got. How toidentify conveyor idler bearing?

First, the identification of the bearing

For the low cost pursue, some smallmanufacturers print the black stamps on the bearing to identify models and manufacturers,with some very simple equipments, electro etching solutions, and very simpletemplates. 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, withno breakpoints, and are never disappeared. This obviously improves the bearinggrade.

The use of bearing retainer

Bearing retainer selection is veryimportant. Because once too much dust stuck into the bearing, the retainer willbe first worn. If the bearing retainer is broken, the bearing will be directlybroken. Imported bearings use big rivets to thicken retainers. XKTE bearing iscompletely in accordance with the process of imported production, so each pieceof ours is made to a high quality, and guaranteed to operate for thirtythousand hours.

Bearing material and hardness

Good conveyor idler bearing must be made ofbearing steel, named "High Carbon Chromium Bearing Steel (Fully quenchedclass) GCr15". At present the standard hardness of conveyor idler bearingis 60-65 degree, while hardness of ring is 61-62 degree, andball is 64-65degree.

The simple way to identify conveyor idlerbearing is to see if its hardness is over 60 degree, because only bearing steelcan get over this degree.

Grease selection of roller bearing

Many customers ignore this most criticalpoint. The thirty-thousands-hours operation is a very long term. This has to beguaranteed by enough quality and quantity grease. And this should also be takeninto account of working in different seasons.

Special note: please choose special hightemperature grease if working environment is over 120 °C for long time or lowtemperature grease if it below -20 °C.
