Ball Guides（Sale Type：Retainers）

[Features]·Miniature ball guide bushing ball slider standard type. ·Ball retainer material is equivalent to C3604.

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

Recommended for use with a hardened shaft and outer diameter tolerance (k5, m5, n5, p5).
[Features]
· KS/BS type incorporates a large number of precision steel balls as stipulated in JIS B 1501 (sphericity, diameter variation: 0.0005 mm) with lightweight and highly rigid cage.
· The balls are spirally arranged around the circumference of the ball cage and designed so that the tracks of the balls do not overlap. This ensures that the balls will not wear for a long time and that high-accuracy can be obtained over a long product lifespan.
· Also, because the finishing of the pocket parts holding the balls is precision and the balls are prevented from falling out by a unique continuous self-clinching method, smooth movement can be obtained even if the ball cage is used for longer than the housing.
· Suitable for application in precision press die sets, textile machines, precision measuring instruments, automatic recording devices, medical equipment, machine tools of various types, etc.

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.
