4. FAQ

Q: What unique advantages does anti-crack NBR have over ordinary rubber materials?
A: Different from common rubber that is easy to crack after repeated bending and exposure to moisture, this anti-crack NBR is optimized with special formula to enhance tear resistance and fatigue resistance. It can withstand countless times of bending and compression without developing cracks. It also maintains stable performance in humid air and intermittent contact with water, and will not swell or harden after long-term contact with hydraulic oil. It is highly adaptable to the complex environment of construction sites, farmland and garden yards where the equipment frequently moves between dry and wet ground.

Q: In what aspects does flexible PU stand out when working as the main dynamic seal?
A: This flexible PU material abandons excessive hardness while retaining basic wear resistance. It can closely fit the cylinder rod and piston during high-frequency reciprocating movement. Even under continuous slight vibration generated by the track chassis, it will not separate from the matching surface or lose sealing tightness. It resists slow creep and permanent deformation, and can keep consistent sealing effect for a long time under light and medium loads, which is very suitable for the frequent operation rhythm of compact track loaders.

Q: What is the working principle of talc-filled PTFE backup rings when cooperating with main seals?
A: Talc filler improves the compactness and self-lubricating property of PTFE material. Mounted beside the main PU seals, these backup rings fill the tiny gaps of installation grooves completely. When the loader suddenly lifts materials or tilts the bucket to produce instantaneous pressure peaks, they share partial pressure evenly and limit the displacement of main seal lips, effectively avoiding extrusion damage. In addition, its excellent lubricating property reduces running resistance, making the cylinder move more smoothly and saving hydraulic power consumption.

Q: What functions can textile laminate guide rings achieve during piston operation?
A: When the bucket bears uneven materials, the piston will be subject to unbalanced lateral force. The textile laminate guide ring can buffer and offset this eccentric force in real time, guiding the piston to move along the central axis stably. It lowers the direct friction between metal piston and cylinder wall, reduces operating noise, and slows down the wear of precision metal parts. The layered structure also enhances shock absorption, adapting to the slight jolts when the track loader travels on uneven ground.

Q: Are all parts produced strictly according to OEM size specifications?
A: Every seal, O-ring, backup ring and guide ring is manufactured in full accordance with original equipment drawings and dimensional standards. The outer diameter, inner diameter and thickness of each component are fully consistent with original parts. During on-site replacement, maintenance personnel do not need to cut, grind or modify the cylinder grooves, and all parts can be installed in place accurately.
