Standard-size Precision Lab Jack
■The Precision Lab Jack is a large Z-axis stage that uses a pantograph mechanism for its movement guide and can adjust the height of heavy objects.
■By rotating the knurled knob, the stage surface can be moved vertically.
■Since a pantograph mechanism is used, the amount of movement in the Z direction changes with each rotation of the knurled knob.
■Products that can be attached to Precision Lab Jacks include top plates and height adjustment plates.
Small-size Precision Lab Jack
■The Small-size Precision Lab Jack is a Z-axis stage that uses a pantograph mechanism for its moving guide and allows for fine adjustment of height.
■The RJ-99M is compact and palm-sized, allowing for efficient use of space.
■The RJ-100M is a small jack that can lift and lower medium loads.
■Vertical movement by rotating the knurled knob uses a micrometer-level fine pitch (screw pitch 0.5 mm), allowing for fine adjustments.
■By connecting the RJ-99M to a stage product with a 60mm square size, and the RJ-100M to a stage product with an 80mm square size, multi-axis adjustment is possible in addition to the Z axis.
■As an optional part, we also have a lineup of ferromagnetic plates that can be fixed using magnetic force.

Large Precision Lab Jack
■The precision lab jack is a large Z-axis stage that uses a pantograph mechanism for its moving guide and can adjust the height of heavy objects.
■The RJ-104 can be adjusted to a travel distance of 100 mm.
■By rotating the knurled knob, the stage surface can be moved vertically.
■Since a pantograph mechanism is used, the amount of movement in the Z direction changes with each rotation of the knurled knob.
■The four U-shaped mounting slots on the four corners of the 100.8mm square can be connected to millimeters and inches.
| Model Number | Stage Size | Z-axis Travel Range | Rated Load | Price (excl. tax) |
| RJ-104 | 170×270 mm | 100 mm | 30kgf (294N) | 120,000 JPY |
Heavy-Load Lab Jack
■The Heavy-Load Lab Jack is a large Z-axis stage that uses a pantograph mechanism for its moving guide and can adjust the height of heavy objects (50 kgf (490N)).
■The RJ-105HL can be adjusted to a travel distance of 100 mm.
■By rotating the knob, the stage surface can be moved vertically.
■Since a pantograph mechanism is used, the amount of movement in the Z direction changes with each rotation of the knob.
■The four U-shaped mounting slots on the four corners of the 100.8mm square can be connected to millimeters and inches.
| Model Number | Stage Size | Z-axis Travel Range | Rated Load | Price (excl. tax) |
| RJ-105HL | 230×330 mm | 100 mm | 50kgf (490N) | 400,000 JPY |
Medium-size Precision Lab Jack with Single Pantograph
■This lab jack has a single pantograph mechanism that allows for 70mm of lift adjustment.
■The height position of the adjustment knob does not change during operation, making it effective for embedded applications.
■The four U-shaped mounting slots on the four corners of the 100.8mm square can be connected to millimeters and inches.
■The shape and position of the tapped holes on the stage surface are millimeter specifications for the RJS-1218M and inch specifications for the RJS-1218 I.
■An optional plate, sold separately, allows you to use metric and inch specifications for the shape and position of the tapped holes on the stage surface.
| Model Number | Stage Size | Z-axis Travel Range | Rated Load | Price (excl. tax) |
| RJS-1218M | 120×180 mm | 70 mm | 10kgf (98N) | 63,000 JPY |

■The Ultra Mini Jack has a stage surface of 60mm square.
■Single pantograph mechanism allows for 25mm of height adjustment.
■The height position of the adjustment knob does not change during operation, making it effective for embedded applications.
■The Ultra Mini Jack can be connected to other 60mm size stages.
■In addition to RJS-60M as the standard specifications (for use in air), we also have RJS-60MV as the version for vacuum environments.
