Ball cages, disposed on oblique axes to ensure maximum precision and a longer duration of the guides.
Structure
The ball cages are made in brass, aluminium or plastic (POM), with balls arranged according to predetermined angles and intervals.
Typology of material
Brass + ball cage in steel
Aluminium + ball cage in steel
Plastic (POM) + ball cage in steel
Characteristics
Low friction. Long duration. Greater precision of movement. Handling both vertically and horizontally. Same advantages of the roller bearings: High working speed.
Applications
They are used in:
- Punching machines
- Presses
- High precision machines with linear and rotational movements
- Guide columns stamping machines
- Woodworking machines
- Textile machines with floating shafts
- Shafts with axial movement, combined radial movement
- Dry movement, without lubricants, in chemical/pharmaceutical machinery
- Movement of groups of lenses on optical instruments
- Micro-ball cages for measuring instruments
For the use of ball retainers, is raccomended to couple them with:
