Product Description

Double Sealed Nylon Retainer Bearing 6308 is reinforced polyamide deep groove ball bearing with suffix TN9 or KA. It is usually used in mining conveyor idler roller. In dusty harsh environment, XKTE use thicker inner outer rings and high quality cage, which have good anti-seizing performance. KA series is appointed cage in China used in mining bulk material handling conveyor.

Clearance:

Select the large internal clearance (ie. C3, C4) here is very important. It compensates for shaft deflections. conveyor bearings cannot use standard bearings, they will cause big running resistance, brake and reduce lifetime of bearing. And 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.

XKTE - Ball Bearings and Rolling Bearings in Conveyor Technology

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

KA Series Type Nylon Bearing:Open Type and One Side Seal Type

*One side seal type

TN9 Series Nylon Bearing with glass fiber

Design Characteristic:

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.

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.

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.
