Our proficient production technique, complete inspection regulations and advanced test devices and methods all ensure the stable and reliable quality of our idlers.
We can also tailor, design and produce non-standard idlers with different specifications and usage.
--High-frequency welded roller exclusive steel pipe
--High precision and quality;
--Provided by industry well-known manufacturers
--Even thickness, good roundness, low runout
--Good dynamic and static balance performance
--Precise machining equipment and strict processing technology;
--The tolerance and the parameters of the shaft are higher than the national standard (GB/T 3078-1994);
--The bare pull shaft with good rigidity and corrosion resistance;
--Increased roller axis hardness extended the service life
CK Roller- Bearing seat
-- Material: cold rolled strip steel with good quality;
-- Processing: many times of stamping and forming, processing the end surface and the ex-circle simultaneously;
-- Surface treatment: Degreasing and phosphating
-- Features: even thickness, good strength, high size precision; ensuring the concentricity and flexible rotation of the two ends of the roller
-- High quality deep grooved ball bearing with clearance of level C3 or C4.
-- Put Long-term lithium grease is put into the internal space, accounting 1/2~2/3 of the total space to effectively ensure the service life of the bearing.
CK Roller- seal assembly
-- Non-contact labyrinth seal composed of internal and external parts;
-- Filling with high quality lithium grease to prevent the lubricating oil from oxidation loss;
-- Good dustproof and waterproof performance;
-- PA/ABS material has good stability, corrosion resistance, low water absorption rate and low possibility of deformation.
Way of shop inspection
|Name of inspection||Way of inspection||Necessary performance|
Waterproof and dust proof
Put the roller in the testing device of coal ash and raining and run by motor at the speed of 1450r/min
|After 200h operation of ash device, the ahs inflow in the grease should not exceed 0.5%(0.8% in MT/T665-1997; after 200 operation of raining device, water inflow should not exceed 100g( 120g in MT/T665-1997)|
|Apply the imported roller strengthened service life platform; install the roller in a sealed container with a 2.25 times of actual operational load. Run the roller by motor at a 3 times of actual operational speed. Suspend 1h after operating for 5h, the total operation time should not be less than 600h.|| |
The normal service life of a roller is 30000-50000h, damage rate within effective period should not exceed 8%( In GB/T10595-2009, the service should be not less than 30000h and the damage rate should not be less than 10%)
|Run the roller on the testing platform at the speed of 1450r/min continuously for 15minutes. And put it in the environment of 20-25ºC for 2h, and test the rotary resistance in accordance with the normal speed and load.|| |
Comply with GB990-91,MT821-2006,
|Rotate the roller for one circle on the radial runout platform, measure the runout value in three axial position and consider the max.||<= 0.5mm( roller length<=550mm)|
<=1.0mm( roller length>950-1600mm)
|After installation, put 500N axial load on the shaft end of the roller||Measured value<0.4mm,|
In national standard, the value is <=0.7mm
