CK Roller-pipe--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 performanceCK Roller-Shaft--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 lifeCK 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 rollerCK Roller-bearing--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.1. Rotating resistanceHow to test
Run the roller for 20 min at 1450r/min, then run for 10 min at 600r/min under 250N radial load to test rotating resistance2. Radial runout How to test
Rotate the roller for one round and measure the radial runout at three axial positions then consider the Maximum value.3. Axial movement How to test
Impose 500N axial load to the end of shaft after roller assembly. 4. Water-proof&dust-proofHow to test
Install the roller in the testing device with dust and pouring water, run the roller by the motor at the speed of 600r/min.5. Reinforced service lifeHow to test
Put roller in a closed container with 2.25 times of actual load, run the roller at a speed 3 times of actual speed, run for 5h and stop for 1h, run at least 600h in such way.
