Imported seamless rolled rings (forged rings) are primarily used in our production.

Our company imports raw materials from many different suppliers in Europe, has a wide supplier network in this regard.

Raw materials are used in our standard manufacturing, are imported with material analysis reports and EN10204 3.1 Certificates and these are matched with serial numbers and are recorded to correspond traceability in standard of quality.

In special manufacturing as per the usage areas; the raw materials with the following certifications (EN10204 3.2) are also procured.

• Bureau Veritas
• I.S.P.E.S.L.
• Lloyd’s Register of Shipping
• T.U.V.
• Det Norske Veritas

The surfaces, where the bearing is assembled to the machine, should definitely be smooth and processed. The factors that will prevent the bearing from rotating, such as welding tensions, dye accumulations or burr etc., have to be removed definitely. The surface flatness should definitely be checked before the assembly.

The Surface Flatness tolerances in relation therewith are indicated in Table 1.

The products such as filling materials, shims etc. should definitely not be used in the mounting. After the bearing is assembled to the surface, it should be rotated a few turns and it should be checked whether there is any clamping.

During the assembly, 10.9 bolt in compliance with DIN 267 should be used and it should be screwed at the tolerances as indicated in Table 2. The screwing operation should be performed as indicated in Figure 1.

Mastery in Measurement, Quality in Production

The Dea delta slant performance 3D coordinate measuring machine is a 3-axis CNC-controlled coordinate measuring machine that operates with portal technology.

X axis max. 3000mm
Y axis max. 5100mm
Z axis max. 2000mm

The standard packaging type provides protection up to 2 years in room temperature.

After the external surface of the bearing is covered with the protective grease TECTYL 506 or OKS 500, the bearing is packed by being wrapped with a special dehumidifier protective paper. The product is made ready for shipment by means of being fixed on a wooden palette.

Pursuant to the qualification of the product to be shipped and the demand of the customer, special carriage apparatus or special cases may also be made.
