PMI :Ball Spline- SLT/ SLF Series *product1
 The Ball spline shaft has three of load groove on the circumference, and the Goethe arch groove design can make sure three grooves can withstand clockwise or Counterclockwise of torque at the same time, increase the life and rigidity. The rows of balls are held in a special resin retainer incorporated in the spline nut so that they smoothly roll and circulate. With this design, balls will not fall even if the nut is removed from the spline shaft.
Features:
*Large Load Capacity -Every groove on the PMI Spline shaft is precision ground to form a 30° angular contact point, having a large load capacity in the radial and torque directions.
*No Angular Backlash-At a contact angle of 60° to provide a preload in an angular-contact structure, this eliminates an angular backlash in the rotational direction and increases the rigidity.
*High Rigidity -Since the contact angle is large and an appropriate preload is given, high rigidity against torque and moment is achieved.
*Ball Retaining Type-The use of recirculation structure prevents the balls from falling, even if the spline shaft is pulled out of the spline nut.
PMI :Cross Linear Guideway- MSH Series/SMH Series
Balls roll four rows of raceways precision-ground on a rail and a carriage, and end cap incorporated in the carriage allow the balls to circulate. Since retainer plates hold the balls, they do not fall off¬ even if the rail is pulled out. This model is an integral type of linear guideway that squares an internal structure similar to other model, which has a proven track record and is highly reliable, with another and uses two rails in combination.
The two rails are also machined with high precision in relative straightness. As a result, extremely high accuracy in orthogonality is achieved. Since an orthogonal linear guideway system can be achieved with model MSH alone, a conventionally required saddle is no longer necessary, the structure for X-Y motion can be simplified and the whole system can be downsized.
We provide not only the cross-type MSH series, but also the patent of ball chain design for SMH series can make the movement smooth and stability, especially suit for the requests of high accuracy equipment.
