EMPRAL Mills Bearings are dimensioned accurately and machined with high precision numerical control machines, eliminating the need of adjustment that enables the interchangeability between the bearings.
In the top bearings, the EMPRAL mills have innovated using the solid lubrication (graphite) between the bearing and the housing. Today, it innovates using Vesconite, self-lubricant material with the characteristics such as: long life, zero of dilatation, high strength to loads and chemical wears.
Specially designed to support high pressures, the hydraulic heads are fixed through tapered keys, eliminating gaps, therefore making easy the vertical removing and allowing a quick maintenance. They have a piston coated of high stiffness ceramic material, eliminating wears and risks.
The head internal body is machined in high precision numerical control machine where the seal rings shall be placed.
Between the piston and the bearing housing, there is socket joints system transmitting the hydraulic load to the shafts, eliminating lateral loads.
In order to solve the problem of shafts and bearings premature wear, EMPRAL has developed special seals. The special seals are composed of rubber retainers, a series of stainless steel rings and a rubber bellows coated with Teflon thus absorbing the gap in the assembly.
In early 2014, the EMPRAL deliver two units of the largest mill in the world in size and milling capacity.
For 37 years EMPRAL Piracicaba research and develops technologies for milling of cane sugar, and for 23 years licenses these technologies.
The EMPRAL, sales leader since 2008, is specialized in offering projects for high milling capacity, maximum performance and low maintenance.
