Heavy Guide Support Roller and Bearing Housing Assemblies
High-tonnage conveying systems in power and steel plants operate under continuous mechanical load. Support rollers, pulley drums, and bearing housings undergo intense friction, vibrations, and dirt contamination. Bearing failure on raw material conveyor belts can halt entire feeding zones.
Excellors manufactures heavy-duty conveyor support rollers, drive pulleys, and customized cast bearing housings. Built for long-term load distribution, our assemblies feature high-grade spherical roller bearings, multiple labyrinth dust seals, and solid structural steel support blocks.
Key Structural Advantages
- Heavy-Duty Bearing Housing: Cast iron housings designed for high shock-load absorption.
- Labyrinth Dust Seals: Triple-lipped seals keeping fine coal, sinter, and dust out of bearings.
- Precision Shaft Machining: Shafts milled and grounded on CNC units to eliminate rotation deviations.
- Stress-Relieved Frame: Welded support frames stress-relieved before final machining.
Project Context
Scope: Manufactured and supplied replacement conveyor drive pulleys and bearing blocks for a major bulk sinter conveyor line.
Result: The custom dust-proof seal design reduced bearing grease contamination, doubling the maintenance service interval from 6 months to 12 months in a highly abrasive sinter dust zone.
