Ball Guides（Sale Type：Bushings）

The compact type has a bushing outer diameter that is 1 to 2 mm smaller than the standard type for the same shaft diameter, making it possible to save more space.

[Features]·Standard type bushing with flange for miniature ball guides. [Material]·This is SUJ2.

Recommended for use with a hardened shaft and outer diameter tolerance (k5, m5, n5, p5).
[Features]
· MST type is configured from an ST shaft, ball cage, and outer cylinder, and these can be freely combined according to the specification.
· Due to small cross-sectional area and minimal gap, and as the movement is very light and smooth, it can be used in various small precision measuring instruments, including spindle of optical measuring instruments, pen plotters, office automation equipment, computer terminal equipment, automatic measuring scales, digital measuring devices, solenoid valve, etc.
· High-precision bearing: A precision steel ball (sphericity, difference: 0.0003 mm) specified in JIS B 1501 is incorporated in a copper alloy ball cage to guarantee high-accuracy. Furthermore, ball is prevented from falling by a unique retention method.
· Bearing with excellent durability: The ST shaft and outer cylinder are heat-treated and ground from carefully selected materials, and the rolling surfaces are super-finished.
· Because the ball arrangement of the ball cage is dense, and the balls are arranged such that the ball tracks do not overlap, it will not wear for a long period of time and provides excellent durability.
· Compact bearing: Use of 1 mm diameter ball and a thin outer cylinder enables a design that has a small cross-sectional shape and takes up little space.
· Bearing with extremely low frictional resistance: ball and rolling surface are in point contact, so rolling loss is extremely small and low-friction rolling motion is possible.
