covers specificationS
Rubber covers for elevator belts have two main functions: protection of the carcass against material and
moisture aggression, assurance of the perfect bucket holding up without bolt loosening in course of time.
In order to guarantee safety and longer life, under hard working conditions too, all type of rubber
covers are antistatic and ozone protected.
Elemet
SX - Medium temperature resistance
SX is a rubber compound assuring resistance against abrasion; it is formulated for maximum temperature
of 100°C. It is not oil resistant.
BX - Superior temperature resistance
BX is the rubber cover that assures the maximum heat resistance for a rubber compound. It is designed
to work at maximum temperature of 180°C. It is not oil resistant.
Eletex
OX - (G grade DIN 22102) Oil resistant quality
OX is a standard rubber compound designed for elevator belts working at ambient temperature. This
compound is antistatic according to ISO 284 and oil resistant too.
AX - High temperature resistance
AX is a rubber compound especially designed for textile elevator belts to guarantee good performances with
abrasive and hot materials up to 150°C. This compound is antistatic according to ISO 284 but not oil resistant.
BX - Superior temperature resistance
BX is the rubber cover that assures the maximum heat resistance for a rubber compound. It is designed
to work at maximum temperature of 180°C. It is not oil resistant.
AG - (K+G grade DIN 22102, class 2A EN 12882) Self extinguish and oil resistant
compound
AG is a nitrile compound typically designed for bucket elevator systems used in cereal silos. It provides
superior resistances to vegetable oils and animal fats; it is also selfextinguishing and antistatic according
to ISO 340 and ISO 284 or equivalent in order to guarantee high safety into the conveyor plant. The
maximum allowed temperature of the conveyed material is 100°C.

fastening
Metal clamps are the most common method for elevator
joining. Typical application is shown on the left. Vulcanized
splicing are possible too; the efficiency is very high but the
vulcanization in vertical position needs special procedures,
tools and skilled people.

Elevator belt calculation
In this section our method of calculation for For the calculation of the minimum tensile strength
