FAQ1: What is the difference between ZARF series bearings and Standard Ball Screw Support Bearings?
While both support ball screws, they do it differently:
| Feature | Standard Ball Screw Bearings (e.g., 7602 Series) | ZARF Series Bearings |
| Roller Type | Uses steel balls (Angular contact). | Uses needle rollers (radial) and cylindrical rollers (axial). |
| Load Capacity | Medium to High. | Extremely High (Rollers have more surface contact than balls). |
| Mounting Style | Must be pressed into a housing and held with a cover. | Has built-in screw holes to bolt directly to the machine. |
| Stiffness | High. | Super High (Best for very heavy-duty machinery). |
FAQ2: What Applications Combine Needle Roller Bearings?
A “combined” bearing contains both radial needle rollers and axial cylindrical rollers. It is used in heavy-duty machinery because it can support loads from multiple directions simultaneously:
a. CNC Machine Tools: Especially on the main shafts and rotary tables.
b. Precision Gearboxes: Where shafts experience massive pushing and spinning forces.
c. Robotics & Automation: For heavy robotic joints that require high accuracy and no wobbling.
