Sliding component solutions
Compare modified POM options for molded bushings affected by wear, binding, clearance drift, or housing retention. Treat the polymer, shaft, housing, fit, motion, lubricant, and environment as one sliding system.
For cylindrical, flanged, pivot, linkage, guide, and actuator bearing sleeves.
Wear, noise, binding, or clearance change can originate in the compound, shaft, fit, alignment, contamination, or duty cycle. Diagnose the complete interface before changing material.
Check bearing pressure, speed, shaft finish, alignment, temperature, contamination, lubrication, and the actual wear pattern.
Screen wear-resistant or low-friction POM only when the shaft-and-bushing interface remains the limiting factor.
Measure the installed bore, housing interference, shaft alignment, startup torque, operating temperature, and real running clearance.
Consider a friction-modified formulation only after fit, deformation, and thermal-clearance causes are separated from material behavior.
Inspect the contact pattern, bore taper, shaft straightness and damage, housing distortion, seals, and the source of particles.
Compare tribological compounds only after edge loading, rough counterfaces, and abrasive contamination are controlled.
Review housing tolerance, interference, lead-in geometry, insertion force, retention features, wall balance, and service temperature.
Compare balanced or reinforced POM only when assembly strain and retention geometry are already appropriate.
Candidate materials
Compare the options below against the installed fit, shaft condition, load, speed, lubrication, environment, and target life.
A baseline POM option for precision molded sleeves needing dimensional stability, moldability, useful stiffness and toughness, and stable sliding behavior.
A candidate when measured wear, startup friction, stick-slip, noise, or interface temperature limits an otherwise sound bushing system.
Lower published friction does not guarantee lower wear. Compare both bushing and shaft condition under the real motion and contamination profile.
A reinforced option when stiffness, creep, housing support, or load-induced deformation matters more than minimizing tribological complexity.
Fiber orientation can change bore geometry, warpage, shrinkage, and counterface wear, especially in small precision sleeves.
Minimum project input
A drawing and the current operating conditions are enough to begin. Remaining details can follow after the first response.
A material shortlist, available grade data or document path, and a proposed installed-bushing evaluation plan.
Validation boundary: Production approval still depends on the complete sliding assembly.
Project input
Send the drawing and available shaft, fit, motion, environment, target-life, and failure data. Taiyi Polymer can compare relevant PLATFORM POM directions, identify available grade data, and propose an installed-bushing evaluation plan.
