Product Description
What is linear bearing? 

Metal linear bearing is a low-cost production of linear motion system for unlimited travel with the cylinder axis. Since the ball bearing point contact with the shaft, so use the load is small. Minimal friction ball rotation, thereby to obtain smooth movement precision. Plastic linear bearings are self-lubricating properties of a linear motion system, the biggest difference is that the metal in the metal linear bearings linear bearings are rolling friction, is the point contact between the bearing and the cylinder axis, so this suited for low load speed movement; while plastic linear bearings are sliding friction is between the bearing surface contact with the cylinder axis, so this low-speed movement for high loads.

Linear bearings are used in conjunction with hardened linear drive shaft. For infinite linear motion systems. Load the ball and quenching transmission shaft because it is the point contact, allowing the load is small, but linear motion, friction smallest, high precision, fast movement.


Feature of linear motion bearing :

(1)Linear motion bearing is a kind of low-cost metal for producing linear motion system, which is used for infinite stroke cylindrical shaft.. Because point contact ball bearing with shaft, so using the load is small.  

(2) the flange linear bearing can be divided into: round flange type, method type, elliptical flange type, guided round flange, guiding method, guide the elliptical flange type, extended round flange type.

(3)According to the specification is divided into two series of LM and LME series. Its code LM series used in Asia,  Japan, South Korea, China, etc.On the basis of metric size, with straight axis diameter tolerance is usually h7.LME series used in Europe, the United States, Germany, Italy and other regions.On the basis of inch size. Also have metric size, with the straight axis diameter tolerance is usually g6.The two series of structural features are basically the same except for different sizes and tolerances.

What's the feature of your linear ball bearings?

The linear ball bearing (also called ball bushing or shaft guiding) consists of a polymeric cage with raceway segments made of hardened steel to guide the ball sets within the complete system. Recirculating balls provide unlimited stroke at low friction movement.
