Component Description
1 Ground Screw and Ground
Label Use the labeled M5 x 0.8 - 6H ground screw to connect the linear stage to a facility safety ground.
2 Bearing Lubrication Ports These capped ports provide access to the linear bearings without dismantling the linear stage.
3 Carriage This is where your load mounts. The carriage has mounting holes and pilot guide holes.
4 Top Cover This protective cover has magnetic edges that keep the upper edge of the strip seals in place.
5 Side Cover These protective covers have magnetic edges that keep the lower edge of the strip seal in place.
6 Cable Track Module This assembly may be a single or double track unit. It contains the power and I/O wiring for base linear
stage and the secondary axis. Multi-axis stages with direct drive base and secondary axes will have a
double cable carrier on the base axis and a single carrier on the secondary axis. The cable carrier
replacement modules come as a complete unit that service the base and secondary axes. It facilitates
quick and easy replacement of this wear item and is available as a spare part.
7 Stainless Steel Strip Seal These replaceable flexible stainless steel strips permit the linear stage to move while isolating the
internal mechanism of the linear stage from the users environment. Keep the strip seals clean, and never
apply a lubricant as this attracts contaminants.
8 Seal Guide These guides allow the strip seal to move smoothly around the carriage of the linear stage.
9 Seal Strip Clamps These clamps hold the strip seal in place. When replacing the seal strips, they are used to position it so it
lays smooth against the top and side covers.
10 Magnetic Encoder
Readhead This encoder readhead has a 5 micron resolution and very low maintenance needs.
11 Encoder Strip Part of the encoder system that provides magnetic encoded polarities to the encoder readhead.
12 Bearing These support bearings guide the carriage on the bearing rail and require periodic lubrication.
13 Bearing Rail These rails provide the linear track that the carriage assembly rides on, they should be kept free of debris.
14 Motor Coil This coil is part of the two piece linear motor. When it is excited by a drive, it generates magnetic forces
which interact with the magnet track creating motion. LC motor coil shown here. LZ motor coil is a
different configuration but works the same way.
15 Magnet Track This track of powerful static magnets is the other half of a linear motor. LC magnet track shown. LZ has a
magnet channel but works the same way.
16 Ball Nut Lubrication Port This capped port provide access to the ball nut without dismantling the linear stage.
17 Ball Screw Shaft This is part of the mechanical power system on ball screw linear stages. This shaft should be kept free of
debris.
18 Ball Nut Transfers mechanical power from the ball screw shaft to the carriage. It requires periodic lubrication.
19 Side Cover Support These supports stabilize the side cover on long linear stages.
20 Rotary Motor A bulletin MPLS rotary motor drives the ball screw mechanism. It is a specially configured MP-Series
rotary motor, and is available as a spare part.
21 Air Port Provides an external air supply connection for a ball screw linear stage. You can apply a maximum of 270
kpa (40 psi) pressurized air to minimize the ingress of particulates from a dusty environment.
