The Inner Structure of RollerRoller is composed of a shaft, shell, housing, inner seal, bearing, labyrinth seal, cover, protective cover, and snap ring. This design ensures smooth rotation and long service life.
Seal Structure
The roller uses a non-contact labyrinth seal system, creating a complex, winding, and narrow passage between the inner and outer seal components. This passage is filled with high-quality grease, ensuring excellent waterproof and dustproof performance. As a result, our rollers operate smoothly and maintain their efficiency in harsh environments.
Bearing
Brands: SKF, NSK, HRB, LYC, ZWZ, etc.
The roller features a C3 deep groove radial ball bearing with a bidirectional sealing structure, enhancing its water and dust resistance capabilities.
Shell, Shaft and Housing
The dimensions and specifications of the tube and shaft conform to GB standards. The radial jump, roundness, straightness, and appearance of the components meet or exceed the strict requirements of GB standards. The housing is manufactured using cold-rolled plate drawing, and precise welding is used on both sides of the housing and shell to ensure the strength and rigidity of the roller.
