XKTE - Ball Bearings and Rolling Bearings in Conveyor Technology

XKTE is the specialist in rolling bearing technology for the mechanical application of continuous conveyors.

Special: Our KA(Nylon retainer) series bearings Obtained MA certification, safety certificate of approval for mining products (rollers) in China. With good performance of anti-seize and anti-static.


Ma Certificate

Clearance:

The selection of sealed nylon/polyamide cage is crucial to ball bearing with one(KA/TN-RS) or double seals(KA/TN-2RS), while the material of nylon cage must be pure and has enough toughness and strength, because the cage will get very soft if it is made of bad material or mixed material, thus to make no anti-stuck performance within the bearing. To get safety certificate for coal mining products must use nylon cage bearing.

Bearing Clearance

Conveyor idler roller usually need large clearance bearing such as C3/C4

Feature of our conveyor idler roller bearing (Unique Design for Mining conveyor):


1. reinforced nylon retainer, it has good low noise properties and better sliding characteristics

2. very good corrosion resistance

3. a wide temperature range

4. Product tested by National Coal Science Institute and Provincial Quality Inspection Center. mining standard in China.

5. Good toughness and strength, good anti-seize performance, constantly used in dusty environment and underground environment.

Nylon Cage Ball Bearing Feature



The design of Ductile crown structure of retainer can effectively remove stuck dust objects

Super Finished Surface Technology

Dimensions such as the outer and inner diameters and the width are ground to micrometer (one-thousandth of a millimeter) precision, as is the groove, a key internal structure formed between the inner and outer rings in which balls run.

Super Finished Surface



Thicker Inner & Outer Ring

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.

Thicker Inner Outer Rings
