Motion Control
High Reliability
Groschopp (Sioux Center, IA) has introduced an updated
Brushless DC (BLDC) motor and several gearmotor combinations. Due to the lack of wear components, the BLDC
motor is considered to be a maintenance-free, high reliability motor. Features include:
■
A life of 20,000+ hours.
■
Outside square dimensions of 73.3 to 90.2 mm
( 2.88" to 3.55").
■
Availability in 12, 24, and 163 VDC/115 VAC.
■
A totally enclosed, non-ventilated design.
■
Continuous rated speeds of 2,600 to 3,800 RPM.
■
Continuous rated torque of 1.8 to 10.8 in-lb.

Micro-Poly Lubrication Zero-Max (Plymouth, MN) Schmidt Offset Couplings now fea- ture needle bearings with internal micro-poly lubrication that do not require periodic maintenance. Other features include: Constant angular velocity and torque in a range of parallel shaft misalignments. A sealed bearing feature with no lube fittings. The ability to handle high amounts of parallel offset up to 17". Torque capacities up to 459,000 in-lbs. No imposition of side loads on shafts or bearings which eliminate radial shaft vibrations. www.zero-max.com ■ ■ ■ ■ ■
Low Wear, Low Friction
A new linear guide rail system, identified as the S99GWRM40 and
S99GWRM80 Series, from Sterling Instrument (New Hyde Park,
NY) features heavy-duty, low wear, low friction operation, without the
need for lubrication. Features include:
A specially formulated polymer material for the sliding element.
Lengths of 1,000, 2,000, and 3,000 mm.
A construction of hard anodized aluminum.
An aluminum plate, die cast zinc blocks, and J Polymer bearings.

Precision XY Linear Translation Stage The PI (Auburn, MA) miCos MCS XY precision linear translation stage was designed for industrial metrology applications, such as sur- face metrology, materials research, topographical measurements in semiconductor test & inspection, flat-panel manufacturing, as well as
optical inspection of precision machined parts. Features include:
The ability to handle loads up to 45 lbs.
Resolution as high as 5 nm, 1 nm resolution with reduced
maximum speed.
Repeatability of 0.2 µm.
A novel PIOne interferometric linear encoder.
A 4" travel range in two orthogonal axes.
± 2 µm straightness and flatness of motion, yaw of ± 20 µrad,
and pitch of ± 40 µrad.
