Custom-engineered seals up to 120" ID

An expanded line of spring-energized seals now includes large diameters for use with for slow-speed rotary and reciprocating medical applications. The one-piece, large diameter seals – energized with a Bal Seal Canted Coil Spring that promotes even wear and prolongs service life – offer equipment designers and end users resistance to wear, extrusion, and chemicals.

The low-friction, large diameter seals are available in a variety of FDA-compatible materials. PTFE-based seals are available in sizes up to 120" ID; thermoplastics, which can be incorporated into backup designs, are available in sizes up to 94" ID.

These large diameters answer the growing demand for high-performance sealing options in imaging systems, such as MRI, PET, and CT scanners, addressing dynamic sealing and environmental conditions, including ambient temperature, humidity, and airflow.

Direct-drive linear motors with integrated encoders

Eliminating backlash and providing users with high acceleration, speed, and resolution are SDLM-051 direct-drive linear motors with built-in encoders. Available in several off-the-shelf models, these direct-drive linear motors feature resolutions of 5.2µm (0.000206"), 1.25µm (0.000049"), and sub-micron resolution. Sized at 2" (50.8mm) in diameter and 3.75" (95.3mm) long, and with the linear optical quadrature encoder inside and directly connected to the shaft for accuracy, these motors easily integrate into new and existing applications using threaded features on the front and rear faces of the motor, as well as each end of the shaft.

The SDLM-051 direct drive motors have a 1" (25.4mm) stroke with a continuous force of 5.0 lb (22.2N) and a peak force of 15.8 lb (70.2N). Non-commutated, motors have zero cogging, and the light weight of the shaft allows for high acceleration/deceleration for higher through-put. Direct coupling to the load increases accuracy and resolution. All SDLM-051 linear motors are available with a spring to retract the shaft to a home position in the event of a sudden shutdown.
