Hetai Custom Helical Groove Guide Bushing
Precision Guidance + Active Lubrication for Heavy‑Duty Motion Systems
Hetai custom helical groove guide bushings are high‑performance precision components engineered for smooth linear/rotary guidance, uniform lubrication, and extended service life in molds, automation equipment, hydraulic systems, and heavy machinery. Featuring precision‑machined helical (spiral) grooves, tight tolerance control, and customizable materials/structures, these bushings eliminate dry friction, reduce wear, and ensure stable motion under continuous operation. Fully custom manufactured to your drawings, samples, or performance specifications.
Core Features
- Helical Groove Lubrication Design Precision spiral/helical grooves create an active lubrication pumping effect, evenly distributing oil/grease across the contact surface, flushing contaminants, and eliminating lubrication blind spots. Supports single‑helix, double‑helix, and figure‑8 groove patterns for different motion types.
- High‑Precision Guidance Performance CNC precision grinding delivers tight control of concentricity, roundness, and fit clearance, ensuring stable, low‑noise linear or rotary guidance with minimal backlash. Ideal for high‑precision mold and automation applications.
- Full Customization Flexibility Customizable inner/outer diameter, length, flange type, groove profile, step structure, and positioning features. OEM/ODM supported from 2D drawings (DXF/PDF) or 3D models (STEP/IGS).
- Premium Material Selection Available in bearing steel (SUJ2), alloy steel, carbon steel, stainless steel (304/316), tin bronze, aluminum bronze, and self‑lubricating materials to meet strength, corrosion resistance, and temperature requirements.
- Enhanced Wear & Fatigue Resistance Professional heat treatment (quenching, tempering, carburizing) and surface finishing (polishing, passivation, phosphating) boost hardness, wear resistance, and service life under heavy load and high cycles.
- Flanged & Standard Versions Optional integrated flange for axial positioning and anti‑disengagement, simplifying installation and improving assembly stability.
