It seems like you're asking about a "Delivery Roller with Gear LJ 1020." Based on the description, this appears to be a specific component, likely used in machinery, equipment, or vehicles.

Here’s what I can infer:

These rollers are essential for smooth transport of items, and they may be found in various types of manufacturing, packaging, or distribution systems.

• With Gear: The addition of a gear implies that this roller has a geared mechanism, likely for driving the roller or integrating it with other parts of a system to ensure synchronization and proper movement. It might be part of a gear drive system where the roller rotates due to a motorized gear mechanism.

• LJ 1020: This could be a model number or specific part number. "LJ" could be the manufacturer or series name, while "1020" could indicate a size, capacity, or specific version of the part.
