Linear Ball Bearing Slides
Model Series: Inch Metric
Single Axis LBBS * MBBS Two Axis XYLBBS * XYMBBS
Single and two axis linear ball bearing slides are used whenever a low friction, precision, high speed translational motion is required. Shouldered, threaded shaft ends are standard to secure tie bars to the shafts. Available in inch or metric sizes, linear ball bearing slides are complete with body, shafts, tie bars, grease fittings and seals.
The single axis slide can be mounted either from the body with the parallel shafts and tie bars in motion or it can be mounted from the shaft tie bars to allow the body to be in motion. The two axis XY-LBBS is mounted from either set of shaft tie bars with the body free to establish the the position of the second axis.
A variety of mounting, hole pattern, bearing style and other options are available to augment utility and enhance design flexibility.
CAD files will be available soon for R. D. Dane slides.

Mounting attitude, overhung load condition, torsional load, and inertia load factors effect total bearing load. The maximum load capacity and travel life expectancy of any bearing is indicated below. Formulas to calculate load figures appear in the Engineering Data section.
Bearing Travel Life
The travel life of the bearing can be determined for a given load in millions of inches. Travel life is the distance the ball bushing travels over the shaft during the life span of the equipment. Since all slides are reciprocating, one travel cycle equals two strokes. The cycle travel (twice the stroke distance) is then multiplied by the number of cycles desired to equal the total travel life requirements.
