Self-Lubricated Bearings

FRITEX^®

Multilayer bushing (dry Sliding Bearings) Fritex is a three layer composite product.

• PTFE Fabric with special fibres of 0,40 mm thickness.
• Special Adhesive 60μm thickness.

Self-Lubricated Bearings

Oltec-500

OLTEC-500 is a material suitable for heavy loads at low sliding speed, solid lubricant is provided by Graphite with additive, which is inserted into the bronze structure of the bearings. The base material are CuZn25Al5. The available items in this material are the cylindrical and flanged bush, washers, strips, and special part on customer requests.

• Supporting shell CuZn25Al5;
• Lubricant Graphite + additive

Pre-lubricated Bearings

BMT

BMT identifies an entire sliding bearing family constituted from a low carbon steel support over lined by a second layer of thermally sintered bronze. The lubricated bronze surface is the sliding side of the bearings. With oil or grease lubrication these bearings are ideal for all the applications where high strength, minimum dimensions and low friction factor are required. This material is produced in according to ISO 3547-4 Key S6 Designation CuPb10Sn10. The sintered layer is generally of lead bronze (CuSnPb10) which is ideal for sliding couplings with steel. Standard bronze thickness is 0,30 mm (nominal) which may be increased to 0,40 mm (nominal) and more for extra thickness bearings (BMT-4 bearing line).
