Bearings used in mining applications are normally subjected to extreme conditions in terms of dust, high load and long periods between maintenance points. so bearings are made to a specialist design, good labyrinth seals, positive pressure systems and high strength materials to combat these tough conditions. Nylon cage ball bearings are appointed material in coal mining Conveyor Idler Roller, with better anti seizing and ant static in dusty harsh environment.
KA series Nylon Cage
TN/TNGH series Nylon Cage
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.
About Cage Material:
TN/TNH = Synthetic. Good Running and Torque. 1-Piece Molded Medium Speeds. Temp Range -30°C TO 80°C
TN9/TNG/T9NH/TVH = Glass fibre reinforced PA66 cage. Higher Speed than [TNH". More Strength. Temp Range -30°C TO 120°C plus.
Types: Open, RS, 2RS
KA series bearings include open type and sealed type KAZ or KA RS,

PA66-GF25 Series Nylon Cage Bearing with glass fiber
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.
