THK linear bearing is a low-cost production of linear motion system, for unlimited travel in conjunction with the cylinder axis. As was carrying the ball point contact with the shaft, so use small loads. Linear bearing with minimal friction ball rotation, so that it can be smooth precision movement.
LMH-L series is a cut flange and lower than model LMK-L,allowing compact design.Containing two units of the standard retainer plate, this type is optimal for locations where a moment load is present.Since the rows of balls in the Linear Bushing are arranged so that two rows receive the load from the flat side, a long service life can be achieved

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.
