Product Information

Open-type steel cage linear bearings are a type of linear motion bearing with a steel cage and an open slot.  Key information is as follows:

1. Structural Features

- Body: The outer ring is made of metal (mostly carbon steel/bearing steel), and the inner part is a steel cage (replacing traditional plastic cages to improve strength);

- Open Slot: The outer ring of the bearing has an axial opening (usually one), allowing for fine adjustment of the fit clearance through clamping force, adapting to different tolerance shafts;

- Rolling Elements: Built-in balls/rollers are evenly distributed by the cage to reduce friction.

2. Core Advantages

- Higher Rigidity: Steel cages offer better load capacity and impact resistance than plastic cages;

- Good Adaptability: The open design is compatible with shafts with slight dimensional deviations, making installation more flexible;

- High Durability: The metal structure offers better resistance to high and low temperatures and corrosion than plastic cage bearings;

- Convenient Maintenance: Some models support oil lubrication, extending service life.

3. Applicable Scenarios: Linear motion structures requiring high rigidity and adaptability, such as automation equipment, machine tool guide rails, printing machinery, and packaging equipment.
