Product Description

The mining conveyor belt will require more frequent maintenance compared to more traditional industries as the weight and the volume moved by the conveyor is usually much higher as is the presence or dust and various other rubbles. A typical mining conveyor will use heavy duty Conveyor Rollers or also called Conveyors Idlers. Conveyors can be installed almost anywhere and reduce the security risk compared to forklift and move materials.

XKTE specializes in manufacturing reinforced high quality ball bearing for conveyor idler rollers, good anti seizing properties in hostile dusty coal mining environment.

The most important part of conveyor idler is bearing. It is unique design deep groove ball bearing for conveyor idler roller that meet all challenges: extremely different temperatures, low-speed, bulk materials handling, humidity, dust, dirt, as well as noise and vibration environments.

Clearance:
Open Type Deep groove ball bearings have internal clearance. 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 harsh environment. with good anti-seize performance used in particularly harsh environment.

Tolerances
The standard version of our single-row deep groove ball bearings has the tolerance class P0
(designs with tighter tolerances available upon request)

Conveyor idler Bearing usually need large Clearance such as C3/C4, Reinforce iron retainer or unique nylon retainer(superior anti-static and anti-sticking) and inner/Outer rings, Sealed type, with good anti-sticking performance. While cannot use standard Bearing, they will cause big running resistance, brake and reduce lifetime of bearing.

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

1. Grinding groove and super finished surface technology
2. Thickening inner/outer rings, increases the service life

3. Reinforced Retainer and Stronger Rivet, unique Nylon Retainer Good toughness and strength, good anti-stuck performance,  constantly used industy environment and underground environment.     

4. Guaranteed by enough quality and quantity grease

5. Good laser engraving

continuous working for more than 30 thousands hours ensured.

Details Of Thick Cage

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.

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.
