8. FAQ & Technical Reference
Q1: What steel grades are commonly used for industrial pulley?
Typically, Q235 for standard use, C45 for added strength, and 304/316 stainless steel for maximum corrosion resistance (marine/chemical applications).
Q2: What bearing types are preferred and why?
Ball bearings (deep groove) are preferred for their low friction, higher rpm tolerance, and quiet operation. Sealed bearings extend maintenance intervals and prevent contamination.
Q3: What are the main industrial standards referenced?
ISO 9001:2015 for quality, ANSI B30.26 for hoisting, EN 12385-1, FDA and RoHS for cleanroom/stainless steel variants.
Q4: What’s the difference between single and double wheel pulley?
Double wheel increases load capacity (by 50-80%), stability, and smoothness, ideal for heavier sliding/hanging doors and longer tracks.
Q5: How should pulleys be installed for maximum lifespan?
Mount per manufacturer torque specs, ensure track alignment (<2mm deviation), avoid contamination, and lubricate per ISO/TS 16949 schedule.
Q6: How is anti-corrosion tested and validated?
Salt spray test (ASTM B117) for 96-480hrs, cross-sectional hardness, and long-term field trials. Stainless steel pulley passes >400hrs with no visible red rust.
Q7: What warranty and after-sales support is provided?
18-month defect warranty (can extend to 24 months for bulk), rapid response support (48h), technical documentation, and spare/replacement policy.
