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.

Materials
40% bronze mixed with 60% pure PTFE, brown, green, grey and glod color are available, customized color is also acceptable.
For the PTFE bronze guide tapes with a thickness of 2mm or above, QZSEALS provides a specialized embossed structure on the sliding surfaces. This design features micro-lubricant pockets that significantly improve initial lubrication and promote the formation of a stable lubricant film. These pockets also act as “traps” to embed foreign particles, effectively protecting the entire sealing system from wear. To ensure maximum versatility for both piston and rod applications, QZSEALS typically supplies these guide tapes with double-sided embossing as standard.
Alternative Material Options
Beyond Bronze, QZSEALS offers specialized fillers to meet specific environmental requirements:
PTFE filled carbon fiber: features enhanced mechanical strength and thermal conductivity. It is highly resistant to deformation and wear, making it ideal for high-temperature applications and linear moving mechanisms like slides and guide rods.
PTFE filled carbon graphite: combines the self-lubricating properties of graphite with the strength of carbon. This material offers an ultra-low friction coefficient and superior chemical resistance, perfect for corrosive environments and high-load sliding units in aerospace or automotive industries.
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
