Torque Resistant Ball Bushings

Our Torque Resistant Ball Bushings are a high precision linear motion system.  The bushing as well as the shaft is equipped with ball guide grooves with special gothic profiles.  This 4-point contact design offers a considerable high load capacity and a high rigidity through slight preloading.  High torque values and shock resistance are ensured with this particularly compact space-saving design.  Through optimized load carrying tracks and the polyamide ball retainer a very smooth running is achieved.

For lubrication the ball bushing is equipped with a lubrication hole.  To retain the lubricant inside the bushing the seals at both ends are adapted to the profiled ball guide grooves.
