Latest News from our URB Bearings Supplier

Dear Customers,

We would like to bring to your notice about some actions taken by our Company during last period, in view to increase the quality of our products and to improve the customer satisfaction.

1) General actions

• It was changed the raw material specification by prescribing better qualitative parameters (less micro clearness, low content of oxygen and hydrogen having as direct influence upon the bearing live).
• The overhauling and modernization of heat treatment furnaces having as result a less decarburization layer, better appearance (grey and uniform surfaces) and uniform micro structure.
• The improvement of packing and box handling, their weight being according to the international standards.
• The improvement of the control capacity for bearing elements and bearings in the laboratory by supplying with new measurement and control apparatus and ensuring the air conditioning inside the laboratory ( New quality control equipment like new form Talysurf, 3D measuring instruments) .
• The extension of dimensional ranges, of ball bearings till the outer diameter of 120 mm; the extension of dimensional range of cylindrical and spherical bearings also.

2) Specifically to each constructive group
a) For the radial ball bearings.

• The utilization of high precision balls (Euroball – Italy, Germany).
• The improvement of noise and vibration level by ensuring an increased accuracy of bearing elements and bearings (the overhauling of washing and filtering equipment, the changing of technological liquids and their supplying from recognized suppliers, i.g. Shell).
b) For the thrusts, cylindricals and sphericals.
• The overhauling of fixed hearths for the semiproducts heating in view to ensure the control of heating process and the maintaining of forging temperature.
• The providing of all the equipment with temperature control devices for barrs (in order to avoid the negative effects upon quality due to the raw material subheating).
• The adjustage of small and medium brass cages by using modern technologies of vibrosmoothing and polishing (the aspect improvement).
• The overhauling of cage pocket milling machines, in order to improve their geometrical parameters.
• The overhauling of heat treatment equipment and the improvement of protection atmosphere inside the furnaces to ensure an uniform aspect (grey – metallic) of the threated surfaces and of a decarburized lay of min. 0.02-0.03 mm.
• To obtain better surface roughness for the roller using vibrofinish equipment.
• The ensuring of high geometrical parameters for the generatrix of the spherical rollers using the shoe grinding procedure.
• The testing and using of high performance abrasives in order to get high quality grinded surfaces.
• The 100% control of bearing elements for their framing in the international standards.
• The environment parameter improvement for increasing the clean degree for bearings.
• The continously concern for improving the package (the package strenghtening in plastic foil by applying an additional autoadhezive strip on the outer side of the bearing .

Herewith, we present you some of the new bearing types assimilated in our production range.
