Our Precision Sealing Solutions

High-performance O-ring for robotic joints with dynamic sealing

O-Rings for Robotic Joints

Engineered for high-cycle motion, vacuum compatibility, and chemical resistance. Available in NBR, FKM, EPDM, and PTFE composites. Ideal for end-effectors and rotary actuators.

  • Dynamic sealing up to 10,000,000 cycles
  • -40°C to +200°C operating range
  • ISO 3601 & AS568 compliant
Bonded plate seal for robotic linear actuators with metal core and elastomer lip

Bonded Plate Seals

Metal-reinforced elastomeric seals for linear slides and piston rods. Eliminates extrusion and provides zero-leakage under high pressure and lateral loads.

  • Anti-extrusion design with stainless steel core
  • Compatible with hydraulic, pneumatic, and vacuum systems
  • Customizable lip geometry for speed and torque optimization
Flange seal for robotic joint housings with dual lip and integrated gasket

Tactile Sensor Substrates for Dexterous Hands

Ultra-thin metallic skeletal structures integrated with soft-touch elastomers. Engineered as the foundational core for finger-tip and phalangeal tactile sensing systems.

  • Ultra-low profile, precision-stamped aluminum or stainless steel frame for stable circuit support
  • Composite ultra-soft LSR coating provides a high-friction, sensitive tactile surface
  • Overmolded ergonomic design ensures a permanent metal-to-rubber bond and component protection

Applications in Advanced Robotics

Robotic Arms

Seals for shoulder, elbow, and wrist joints under continuous torsional stress.

Linear Actuators

Bonded plate seals prevent contamination and maintain positional accuracy.

Vacuum Grippers

O-rings and lip seals ensure consistent vacuum integrity in cleanroom environments.

High-Speed Motors

Flange seals protect bearings from debris and lubricant loss at 5,000+ RPM.

Engineered Materials for Demanding Environments

NBR (Nitrile)

Best for oil, fuel, and hydraulic fluid resistance. Standard for general automation.

Temp: -30°C to +120°C

FKM

High-temperature and chemical resistance. Ideal for cleanrooms and sterilization cycles.

Temp: -20°C to +200°C

PTFE & Filled Elastomers

Low friction, non-stick, and ultra-low outgassing. Used in semiconductor and space robotics.

Temp: -200°C to +260°C
