MAKISHINKO BX19 and BX25 Ball Screw Bevel Jacks — 20 and 50 kN Models

The MAKISHINKO BX bevel jack combines a bevel gear transmission with a ball screw to convert rotary input into axial travel. The bevel arrangement supports a mechanically linked drive layout where several lifting points need coordinated motion. The catalog lists two sizes and four input shaft arrangements.

BX19 and BX25 basic specifications

BX19 and BX25 basic specifications

BX19 and BX25 use ball screws, with catalog efficiency of 80%. BX19 advances 4.0 mm per input revolution and BX25 advances 5.0 mm. A ball screw can be backdriven by an axial load. Select an appropriate load-holding arrangement for the application.

MAKISHINKO JA, JAH, JAS and JTA Trapezoidal Screw Jacks — Models and Selection Data

Four trapezoidal screw jack designs serve different travel, packaging and material requirements. JA is the standard translating screw type. JAH increases travel per input revolution, JAS is the stainless variant, and JTA moves the load through a traveling nut on a rotating screw. The model tables retain the nominal, reverse and static load values separately.

JA standard translating screw jack

JA standard translating screw jack

The JA range has 16 standard sizes from JA002 to JA1250. The catalog describes a self-locking characteristic for the standard trapezoidal drive. Verify holding performance under the actual installation conditions. The reducer uses grease on JA005 and JA010, and an oil bath on JA002 and sizes JA025 and larger. Screw lubrication is grease.

JTA trapezoidal traveling nut jack

The screw rotates and the traveling nut provides linear motion, reducing the space needed behind the housing for a translating screw. Restrain nut rotation through the installation and size that restraint using the listed screw torque. The standard JTA table includes 16 sizes through JTA1250.

Information for selection and ordering

Provide the working and reverse loads, stroke, travel speed, operating cycle, screw direction and input shaft arrangement. Standard stroke increments listed for these groups are 50 mm up to 500 mm and 100 mm above 500 mm up to 1,000 mm. Check the selected configuration and drawing. For compression, evaluate allowable unsupported screw length and end support. Use the model-specific load versus speed chart for the duty point.
