Bimetallic sliding bearings with AlSn
Bimetallic thin walled bearing shells with AlSn slide layer.
A20 material consists of two metal layers the steel base is surfaced with the slide lining material AlSn20Cu1. The assembly is ideally suited for use in hydrodynamic lubrication condition for static and dynamic load. The material having the good slide behaviours exhibits both good fatigue strength and good corrosion resistance. In the limiting friction conditions the material shows good working adaptation.
The face hardening of the pin improves the life service. A heat treatment above 52 HRc is recommended. Slide bearings with A20 lining are designed for pins ranging in size from 20mm to 200 mm. Due to their excellent behaviour they are used in slide fits of gasoline and Diesel engines.

We can deliver complete BEKOMAT electronically level-controlled condensate drains and service kits as well. The BEKOMAT range provides the 12, 13, 14 and 16 standard drains for virtually every application, which are not just the correct solution, rather more also the most suitable low-energy solution. The integrated capacitive sensor for level-controlled condensate discharge helps save energy and enhances efficiency – which is what you would expect from a BEKOMAT.
The regular maintenance was carried out in 2 consecutive years by the team of TUNGS-STAR on an ABC Horizon 1400 compressor at Plastipak Romania SRL in Urlati. The 40 bar PET compressor is powered by a 280 kW motor equipped with VSD. It has 3 stages with 4 horizontally opposed cylinders.
New 15 kW MATTEI compressor was installed next to an old 7.5 kW Mattei compressor to assure the increased production of a local company.
