Miniature High-Speed Threaded Track Rollers

Built to handle high speeds for their size. These track rollers have an outer ring that supports higher speeds than standard-sized track rollers. They also create less friction than miniature high-load rollers while spinning. You can use these rollers for precise movements in robots or other miniature applications.
