Linear Bearings

Linear bearing is a linear motion system, used for linear travel and cylindrical axis.Due to coat point contact ball bearing with bearing, steel ball roll with minimum friction resistance, so the linear bearing small friction, and relatively stable, not over bearing speed changes, and can obtain high sensitivity, high precision of stationary linear motion.

The consumption of linear bearing also has its limitation. The most important one is that the bearing has poor impact load capacity and poor bearing capacity.Linear bearing quick and easy to optimize automatic selection included.

Types of Linear Motion Bearings

Both rolling linear bearings and plain linear bearings are designed to provide smooth linear motion. Learn more about which type is the right fit for your next project: 

Rolling Linear Bearings:

Linear roller bearings have balls or rollers in the guide rails, which act as the smooth rolling element to control motion. The rolling elements sit within the housing, and they may be either recirculating or non-recirculating rolling elements. The bearing roller can be large or small, depending on the linear speed the guide demands, and rolling linear bearings are one of the most common solutions for linear motion. Each unit can be customized to have the size and contact angle needed for the assembly’s loading capacity and motion requirements. Small changes in the contact angle will determine the radial loading capacity with a directly proportional relationship; the angle is inversely proportional to the lateral loading capacity. For example, a rolling linear bearing with a 45° contact angle is ideal for general movement, as it can minimize friction when loads are moving radially, reverse radially, and laterally.

Plain Linear Bearings:

Plain bearings can reduce friction and ensure smooth contact between two surfaces. These parts are very simple to use, with simple construction and, as a result, a low production cost. They can handle a large load due to the increased contact surface area, and they can also handle shock and vibrations better than other linear bearings.

How to Choose the Right Type of Linear Bearings?

We can help you choose the right Linear bearing for the job. Some of the factors to consider include:

1.Precision demands, including applications ranging from low-end drawer slides to high-precision industrial equipment.

2.Motion smoothness in high-load operations. This requires materials like bronze.

3.Risk of particulates and contamination within the bushing

4.Friction

5.Stand-alone or assembled goods: Manufacturers can offer a wide range of assembled systems with different actuating options for simple operation.
