Training Idler

The Training Idler responds instantly to the misalignment of the belt without special modifications to the structure. It requires no maintenance and fits into a standard drop bracket. The Training Idler can be manufactured to suit all belt sizes in operation.

Troughing Training Idler

The unique design of the components of the Troughing Training Idler frame allows it to automatically adjust itself to the conveyor belt to correct the misalignment in the troughing section of the conveyor, keeping your conveyor belt on track.

Warrior Impact Bed

The Warrior Impact Bed stabilizes and supports the conveyor belt during loading. Rubber bars of the Warrior cushion the belt and absorb impact resulting in longer belt life, eliminating spillage, and decreased O&M costs. The durable frame of steel supports impact on the bars.

Protection guaranteed. The Warrior Impact Bed includes a sturdy steel frame that stabilizes and supports the conveyor belt during loading, defending it from damage. In addition, the Warrior’s stiff, rigid frame and soft rubber bars cushion the belt and absorb impact.

The Warrior Impact Bed also offers ‘fine-tune’ wing adjustment for optimum sealing, as well as wings and center sections that slide in and out for easy access. Plus, impact bar change-outs are quick, keeping downtime to a minimum. The result is longer belt life, no spillage, and lower operations and maintenance costs.

The Warrior Impact Bed meets CEMA design standards No. 502-1998 and 575-2000.

Warrior Roll & Guide

The Warrior Roll & Guide Support bed creates a seamless seal, helping to eliminate dust and spillage in the load zone. It utilizes low friction slider bars on the wing sections and rollers in the center. Belt drag is minimized while the belt is fully supported at the edges.

The Warrior Roll & Guide Support Bed creates a seamless seal that helps eliminate dust and spillage in the load zone. The support bed uses low-friction slider bars on the wing sections and rollers in the center, minimizing belt drag while providing vital support at the edges. In addition, the adjustable wing sections ensure a flat, level surface for the conveyor belt and the load zone, allowing the sealing system to perform its best.

Easy to install and maintain and fit trough angles, the Warrior Roll & Guide Support Bed increases skirtboard life, removes gaps between the skirtboard and seal, and stops crimping of interior skirt liners.

The Warrior Roll & Guide Support Bed can include center standard or impact rollers. Typical bars and beds are 48” (1200mm). Custom lengths also are available.

Benetech Idlers Features & Benefits

Benetech Sealing System

Benetech’s labyrinth sealing system protects the roller from all types of contaminants found in polluted or corrosive environments such as washdown areas, fine dust, and debris. The sealing system consists of a vertical triple labyrinth seal protecting against dust, a male and female labyrinth seal protecting against water and moisture, and a metal seal against material with particle size greater than 0625in. This combination of multiple seal designs will maintain and extend the life of the roller against abrasive material.

  • Recessed Welds – Protects the belt from wear with the full thickness of the shell.
  • Welded Head – Special formed disc designed to shed water, house inner workings, and create great roll concentricity.
  • External Deflector – Corrosion and the impact-resistant first line of defense. Uses centrifugal force to shed water and abrasive material.
  • Contact Seal – Protects against moisture, stone, and fine materials.
  • Solid Idler Shaft – 1045 Cold Rolled Steel with the slotted shaft to secure the roll to the frame.
  • Triple Labyrinth Seal – 3rd line of defense for the bearing. It creates a longer pathway for harmful material to the bearing.
  • Snap Ring – Locks the seals and bearing in a stationary position to reduce wear.
  • Bearing Housing – Creates an air-tight seal for all working parts as the last line of defense and ensures perfect concentricity of all parts.

Benetech Idlers Features & Benefits

Rolls

The outer and inner body of the roller and the lateral metal covers provide a completely sealed and rigid capsule. During the operational life of the roller, this unique assembly design guarantees the optimal performance of the shaft, bearings, and sealing system.

Housing

The inner body or bearing chamber is a complete piece inside the roller. Its purpose is to guard all of the inner components of the roller out to the head. Unlike other rollers on the market with independent bearing chambers, the main advantage of our design is that perfect concentricity is achieved, therefore prolonging the roller life.

Bearings

Benetech rollers come with top-of-the-line 2RS ball bearings. Due to the construction of these bearings, they provide adequate resistance to radial and axial loads. As a result, the 2RS bearings promote high-level performance and require no maintenance or regreasing during their lifetime.

Welding

Benetech uses robotic Metal Inert Gas (MIG) welding to construct the roller head. With this technology, the weld is more resistant to cracks or breaks. Since a flux is not used, there is no chance of slag entrapment, resulting in a clean quality weld. The MIG weld improves the finish and resistance to normal wear, increasing the lifetime of the roller.

Shafts

Consistently exceeding CEMA standard load ratings, the idler shaft size will be different depending on CEMA class. The roller shafts are manufactured with top-quality grade steel.

The Benetech MaxZone® product line is designed to reduce maintenance time and cost while maximizing material throughput, system uptime, and safety for plant personnel.

Things to be aware of:

There are many different sizes and types of idlers made by multiple manufacturers, so you must order the correct size and type to minimize problems in the conveying system. Incorrect idler sizing or specification can lead to belt damage, cargo spillage, premature equipment failure, or even more catastrophic events. Therefore, take care while ordering and using the correct size frames and idlers in a conveying system. In some cases, the materials used in the construction of the idler frames or idler rolls may not be compatible with the material being handled, and contamination of the conveyed product can occur.
