QZSEALS
PTFE filled bronze guide tape—also known as GST wear strip—is engineered for guiding and supporting pistons and piston rods in reciprocating hydraulic cylinders. It provides precise linear guidance, absorbs radial loads, and prevents direct metal-to-metal contact inside the cylinder.
PTFE filled bronze guide tape features outstanding low-friction properties, excellent dry-running behavior, and high chemical stability. It is suitable for high-frequency, long-stroke, and high-temperature hydraulic applications.
As temperature increases, the allowable load capacity of PTFE materials decreases. For temperatures below 0°C, please consult us for technical evaluation

Applications
The guide tape is widely used in hydraulic and other reciprocating, oscillating, and slow-rotating systems. It is suitable for light-to-medium load applications with limited radial force.
Typical applications include:
Injection molding machines
Shock absorbers
Accumulators
Bulldozers & excavators
Forging presses & ceramic brick machines
Rolling mills & metallurgical equipment
Agricultural and forestry machinery
Conveying machinery
Chemical and marine equipment
Machine tools and construction machinery
Features
Excellent chemical and heat resistance
Outstanding wear resistance & long service life
Extremely low friction, no stick-slip effect
High load-bearing capability; prevents metal contact
Absorbs side loads & suppresses vibration
Allows increased extrusion gaps due to proper alignment
Good dust-tolerance; foreign particles can embed safely
Simple groove design and easy installation
Stable operation across wide media range
