EGHS95F II Ball Screw Actuator

The same stroke does not require the same installation layout

For a short positioning axis, the space occupied beyond the working stroke can determine whether the unit fits inside the machine. The EGHS95F-II Ball Screw Linear Actuator addresses this through four motor arrangements: BC, BL, BR and BM.

The difference is visible in the catalog dimensions. At a 100 mm effective stroke, dimension A is 358 mm for the inline BC arrangement and 288 mm for BL, BR or BM. At a 400 mm stroke, the corresponding dimensions are 658 and 588 mm. Moving the motor connection away from the inline position therefore reduces dimension A by 70 mm in these drawings.

This reduction can help when the ends of the axis sit close to a machine wall or another station. The alternative layouts use space elsewhere, however: BL and BR require lateral clearance, while BM requires room below. Dimension A is a drawing reference rather than the complete envelope of every motor configuration.

The cross-section identifies a 95 mm body width and a 110 mm carriage width. The moving platform therefore extends beyond the body, a detail that matters when two axes or adjacent fixtures are placed close together. The covered exterior shown in the product photograph leaves the mounting platform accessible above the housing.

Inside this envelope, the catalog specifies a Ø16 mm C7 ball screw, two EGR15 rails and two EGH15 blocks. The paired guide paths support the carriage on either side of the drive. This is a two-block arrangement, so a long overhanging fixture should be assessed using its load position as well as its total mass.

Choose the movement within that layout

The EGHS95F-II Ball Screw Linear Actuator has four lead options. A 5 mm lead is listed at up to 250 mm/s with a maximum horizontal handling weight of 60 kg. The 10, 16 and 20 mm versions are listed at 500, 800 and 1,000 mm/s, with corresponding horizontal limits of 35, 25 and 20 kg. Vertical handling figures are 30, 25, 20 and 15 kg respectively.

These are configuration-specific figures, allowing the mechanical layout and motion requirement to be considered together. Published repeatability is ±0.02 mm; it describes return-to-position consistency rather than absolute accuracy throughout the stroke.

The drawings also identify a photoelectric-switch location. Keeping this area accessible allows room for the selected switch and its cable connection, so the final installation should account for more than the motor and moving carriage alone.

About Us

Guangyuan manufactures ball screw actuators and related linear-motion components. For this series, our catalog includes separate BC, BL/BR and BM installation drawings, with stroke-dependent body dimensions and mounting-hole information.

The primary configuration table lists 57/86-frame stepper motors and 100 W, 200 W or 400 W servo motors. The side and lower installation drawings contain more specific motor notes, so the selected motor dimensions should be checked against the required arrangement rather than assuming every combination is interchangeable.

We accept drawing-based OEM/ODM enquiries for mounting and connection requirements. The minimum order quantity is 1 unit. Motor, driver, controller and photoelectric-switch inclusion should be defined in the quotation.
