Industrial Rubber Seals for Machinery and Automation Equipment
Precision Fluid Containment & Severe Environment Protection
XI'AN CHRIS NEW MATERIALS CO., LTD. manufactures and supplies a comprehensive portfolio of industrial rubber seals for machinery and automation equipment. Engineered for high-stress mechanical systems, fluid power networks, and advanced robotics, these sealing components provide an absolute barrier against fluid leakage and contaminant ingress.
By utilizing precision elastomeric compounding and advanced molding technologies, our seals significantly extend the Mean Time Between Failures (MTBF) of critical rotating, reciprocating, and static industrial machinery.
Key Engineering Advantages
Precision Elastomeric Compounding
Formulated with strict control over hardness (Durometer Shore A), tensile strength, and compression set parameters to ensure optimal structural recovery under dynamic loads.
Advanced Contaminant Exclusion
Specifically engineered sealing profiles act as an effective shield against ultra-fine dust, moisture, abrasive particles, and chemical splashes.
Optimized Tribological Performance
Low-friction rubber formulations minimize operational heat buildup, reducing shaft wear and maximizing energy efficiency in high-speed automation systems.
High-Pressure Extrusion Resistance
Specially formulated elastomers retain their geometric profile under severe hydraulic pulsation, preventing seal nibbling and structural failure.
Material Engineering Matrix & Operating Parameters
To ensure accurate material selection based on thermal, pressure, and chemical exposure requirements, Xi'an Chris provides multiple elastomeric sealing solutions.

Technical FAQ for Design Engineers & Procurement
How do I choose between NBR and FKM for a hydraulic pump application?
NBR (Nitrile) offers excellent wear resistance and cost efficiency in mineral oil-based hydraulic systems operating up to +120°C. For systems using synthetic fluids, aggressive chemical additives, or operating continuously at elevated temperatures above +120°C, FKM (Fluorocarbon) is recommended to prevent swelling, hardening, and premature elastomer degradation.
What custom molding capabilities does Xi'an Chris provide?
We provide comprehensive engineering support based on customer-supplied CAD drawings (STEP, IGES, DWG) or physical samples. Capabilities include custom tooling, FEA analysis for seal deformation profiles, precision compression molding, injection molding, and material formulations compliant with FDA, RoHS, and REACH standards.
What are the leading causes of industrial seal failure?
The most common causes include chemical incompatibility, excessive compression set, thermal hardening, and abrasive wear. These issues can be minimized through proper elastomer selection, optimized groove dimensions, and controlled shaft surface roughness values.
What quality control and certifications accompany your products?
Xi'an Chris maintains strict quality inspection procedures from raw polymer testing through finished product verification. Material Test Reports (MTRs), hardness testing, tensile strength data, elongation reports, and RoHS/REACH compliance certificates are available upon request.
