Roller components
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 performance

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 life
Roller- Bearing housing
-- 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
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.

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.
