External teeth, distinct from a conical washer. Check the bearing surface, coating and tightening; the washer alone does not guarantee resistance to vibration loosening.
Table dimensions refer to the stated execution. DIN/UNI, polymer and special variants require verification of their own dimensions; they do not automatically inherit reference geometry, weight or performance.
Materials, classes, finishes and treatments
Other materials, property classes and finishes available on request.
State the required material, property class and finish in your enquiry. The configuration is defined and confirmed in the quotation.
Executions are distinguished by reference, material, class and finish. DIN, ISO and UNI references do not imply dimensional equivalence or availability of every size in each material. Supply and batch documents require quotation confirmation.
For this special execution, body material, any insert, class and treatment must be specified separately. Variants of geometrically similar products are not assigned automatically.
