Roller is composed of several key components including the shaft, shell, housing, inner seal, bearing, labyrinth seal, cover, protective cover, and snap ring. This design ensures stability, durability, and efficient performance in various industrial applications.
Seal Structure
This roller uses a non-contact labyrinth seal design, which creates a complex, winding, and narrow passage between the inner and outer seal parts. The maze is filled with high-quality grease to enhance its waterproof and dustproof capabilities. This advanced sealing system ensures smooth rotation and long-term performance even under harsh conditions.
Bearing
Brand options include SKF, NSK, HRB, LYC, ZWZ, etc. The roller is equipped with C3 deep groove radial ball bearings that feature a bidirectional sealing structure. This improves the water and dust resistance of the product, ensuring reliable operation over time.
Shell, Shaft, and Housing
The dimensions of the tube and shaft comply with GB standards. The tolerances for radial jump, roundness, straightness, and appearance exceed the strict requirements of GB standards. The housing is manufactured using cold-rolled plate drawing technology, and precise welding is used on both sides of the housing and shell to ensure strong and rigid construction.
