传统C型三维效果图

Comparison point:

1. Welding protection and lubrication

The hub type is a box-type structure, which can be replaced by protective welding

Catch splash and lubricate;

The moving parts of the C-type structure are exposed, which is not convenient

Traditional C-type 3D renderings for protection and lubrication.

2. Flip the Angle

Rotating hub type because there is no notch to turn ±180° is very convenient;

The C-type structure is flipped ±180°, requiring two steps or one step

Flip multiple times and press tightly.

3. Failure rate and width

The hub is maintenance-free for standard finished products;

C-type structure multi-stage transmission increases the failure rate;

The hub is narrower than the C-type structure because there is no multi-level transmission width.

Facilitate product holding and welding.
