Eriez Offers Magna-Rails and Magna-Rolls

Magna Rail

Magna Roll

Eriez Magna-Rails and Magna-Rolls magnetically convey, transfer, control, elevate, reposition, hold or orient basic ferrous materials and finished parts. These products have been the industry standard for more than 40 years and are used primarily on automated conveyor lines, the company said.

An ever-present need within many processing industries is the ability to hold steel parts firmly on moving belt conveyors. Such conveyors, fitted with Eriez Magna-Rails, can ensure that parts do not fall off, even when being elevated or lowered. These magnetic elements, positioned under conveyor belts and secured by mounting brackets, provide a safe, positive hold for ferrous parts-cans, sheets, nails, stampings, finished parts, even scrap-at high speeds in any direction, even up inclines as steep as 90-degrees, the company said.

Two types of permanent magnet Magna-Rails are offered, Erium 45 (Alnico) and Erium 25 (Ceramic). Straight sections are available in various holding strengths, and in increments up to 10 feet (3 m) in any one section. They can be positioned to provide any desired length.

In addition to the Erium 45 and Erium 25 models, an Electro Magna-Rail is available for special applications where on/off power is required. Electro Magna-Rails are built with a 3-3/4" (95 mm) face width in standard 12" (304 mm) as well as special lengths.

Magna-Rolls are commonly used in direct contact with steel sheets and tubing. Their firm magnetic grip helps ensure that when the roll turns, the steel moves. Further, when the roll stops, the steel stops as well, thus eliminating the need for pinch rollers.

Magna-Rolls are constructed in several types-with a flat surface or crowned. Contoured and special faces for specific jobs are available, as well as single and multiple gap units. Virtually any diameter from 2-1/2" (63 mm) and up can be supplied in Magna-Rolls. The 2-1/2" (63 mm) and 4-3/8" (110 mm) rolls have a narrow air gap, which provides maximum holding power and traction for a given diameter. The 5-3/8" Magna-Roll has the greatest magnetic strength and can be furnished with either a flat or crowned surface.
