- Linear Bearing -
The LIMON linear motion bearing consists of an outer cylinder, ball retainer, balls and two end rings. The ball retainer which holds the balls in the recirculating trucks in held inside the outer cylinder by end rings.
Those parts are assembled to optimize their required functions. T he outer cylinder is maintained sufficient hardness by heat treatment, therefore if ensures the bearings projected travel life and satisfactory durability.
The ball retainer is made from steel or synthetics resin. The steel retainer has high rigidity.
The synthetics resin retainer can reduce running noise. The user can select the optimum type for meeting the user's service conditions.

The standard type of LIMON linear motion bearing can be loaded from any direction .Precision control is possible using only the shaft supporter,and the mounting surface can be machined easily.
