Seal Sets and Metal Caps for Troughing Idlers and Return Idlers

Seal sets and metal caps are essential components in troughing idlers and return idlers, ensuring the protection and smooth operation of conveyor rollers in harsh industrial environments such as mining, cement plants, ports, and bulk material handling.


1. Seal Sets

Seal sets are engineered systems designed to shield the bearing assembly from contaminants and retain lubrication. They typically consist of a multi-stage sealing mechanism, such as:

  • Labyrinth Seals: Use a complex path to block contaminants without contact, reducing wear.

  • Contact Seals: Include rubber or polymer lips that press against the shaft for tight sealing.

  • Grease Shields: Help retain lubricant and enhance the effectiveness of primary seals.

Functions and Benefits

  • Protection Against Contaminants: Prevent ingress of dust, water, slurry, and other foreign materials.

  • Lubricant Retention: Maintain optimal grease levels, reducing friction and wear.

  • Extended Bearing Life: Minimizes premature bearing failure, lowering maintenance costs.

  • Withstand Harsh Conditions: Designed to operate in environments with high humidity, temperature variations, and abrasive particles.


2. Metal Caps

Metal caps are durable enclosures installed at the ends of the roller to protect the seal set and internal components. Typically made from pressed or formed steel, they serve as the first line of defense.

Functions and Benefits

  • Mechanical Protection: Shield seals and bearings from physical impact and larger debris.

  • Structural Reinforcement: Help maintain alignment and integrity of the roller assembly.

  • Corrosion Resistance: Often coated or galvanized to resist rust in wet or corrosive environments.

  • Aesthetic and Safety Purpose: Cover rotating parts to prevent accidents and present a clean appearance.


Applications

  • Troughing Idlers: Located along the carrying side of the conveyor belt, supporting the load in a trough shape. Require effective sealing due to continuous exposure to material spillage.

  • Return Idlers: Support the empty return side of the belt and are exposed to carryback and environmental conditions.
