NEW RELEASE! ISEL original high precision Z-axis guide specialized for FA equipment.

Million guide case

Million guide caseHigh rigidity, High precision
Line contact by needle rollers makes high rigidity!! Low pre-load and vibration makes high precision without backlash. Million guide has realized highly accurate linear motion, and has reduced defect rate.

Space-saving
Single shaft/unit operation is possible. The equipment can be simple and small.

Good load balance
The guide can be placed on the load center. Well balanced with less biased load, and contributes to accuracy improvement.

Assembly workload reduction
Single shaft/unit is easier to assemble. Reduction of assembly time and components contributes cost reduction.

Conventional case

Disadvantage
  • Low rigidigy and accuracy
  • More components and room
  • Biased load occurrence
  • Difficult adjustment and more assembly time
  • Multiple guide axes

Conventional case

※1 Standard preload (no description): We supply the products whose pre-load is 2-4µm. (No specification in the rolling resistance) Micro pre-load (CL) 1µm or less; the sliding friction=50g or less for ZG9-12, 100g or less for ZG16-20.

※2 Choose the direction where the snap ring is placed downward at the guide installation.

※3 Million guide employs retainer and the retainer may shift in some conditions. Use Million guide within the effective stroke so that it is effective to mitigate the position shift by using within the range where the retainer does not protrude from the bush. Please contact us on another way "spring insert" to restrain the retainer shift.
