FAQ on belt conveyor roller: Professional Terminology

Q1: What materials are most commonly used for belt conveyor roller shells?
A1: Carbon steel (Q235, SS400) is the industry default, combining strength and cost-effectiveness. For chemical/environmental resistance, HDPE or stainless (SS304/316) shells are used.
Q2: What is a "labyrinth seal" and why is it important?
A2: A labyrinth seal is a non-contact, multi-stage groove system that blocks water, dust and contaminants from the bearing chamber. It greatly enhances the operating life of the idler roller in dusty/wet environments.
Q3: What does TIR (Total Indicated Runout) mean in roller specification?
A3: TIR measures the roller's radial accuracy or "roundness" during rotation, expressed in mm. Industrial standards generally require TIR <0.8mm, with Table Roller regularly achieving <0.45mm.
Q4: What is "dynamic balance" testing for conveyor rollers?
A4: Dynamic balancing ensures equal mass distribution along the roller's length during rotation. This minimizes vibration (<1.2mm/s, per ISO 1940-1 standard) and improves bearing life, belt wear, and noise.
Q5: How does surface treatment (e.g., rubber lagging, galvanizing) affect roller performance?
A5: Rubber lagging increases friction and reduces belt slippage, ideal for drive rollers; galvanization provides corrosion resistance in humid/corrosive environments; painted or powder-coated finishes prevent rust but may wear off faster.
Q6: Which standards/certifications are critical for belt conveyor roller?
A6: Key standards are ISO 9001 (quality management), ANSI B105.1 (idler roller tolerances), CEMA (US conveyor standards), GB/T 10595-2009 (China), and DIN 22107 (Germany). For food/pharma: FDA, EU1935/2004.
Q7: How is conveyor idler roller lifespan calculated and what factors influence it?
A7: Lifespan is primarily a function of bearing quality, sealing system, roller load (kg), speed (m/s), and environmental factors (abrasive loading, moisture). Advanced products like Table Roller with double seals and precise balancing can achieve over 40,000 hours per ISO 281 fatigue analysis.
