Frodo or Frodos Lent

Ferodo brake pads are specialized components used in disc and drum brake systems, manufactured in compliance with international standards. Their coefficient of friction ranges from 0.35 to 0.42 and they maintain stable performance within an operating temperature range of 100 to 450 degrees Celsius. The Premier series is designed for passenger vehicles, with the friction material thickness varying between 10 to 16 millimeters. Brake response time with these pads is recorded at less than 0.3 seconds, and they achieve high scores in ECE R90 tests for braking stability and consistency.

The material structure of Ferodo pads consists of a blend of organic fibers, heat-resistant compounds, and light metallic particles such as copper or soft steel. This formulation reduces disc wear and extends pad life up to 40,000 kilometers. Under normal driving conditions, pad thickness decreases by approximately 0.05 millimeters per 1,000 kilometers. At temperatures exceeding 500 degrees Celsius, friction performance drops by only about 10 percent, indicating excellent thermal resistance. These pads feature anti-noise design and cooling grooves that reduce brake noise and vibration by up to 30 percent.

Ferodo brake pads are among the most specialized and reputable products in the braking industry, designed and manufactured in accordance with international automotive and industrial standards. Their coefficient of friction ranges from 0.35 to 0.42, delivering consistent performance across a temperature range of 100 to 500 degrees Celsius. The friction material thickness in passenger car models ranges from 10 to 16 millimeters, with a wear rate of less than 0.05 millimeters per 1,000 kilometers. Ferodo pads are manufactured using multi-groove technology and heat-resistant adhesive, ensuring high resistance to thermal cracking.

The material composition of Ferodo pads includes aramid fibers, phenolic resin, and soft metallic particles such as copper or graphite. This blend balances braking power with reduced rotor wear. Their compressive strength reaches up to 25 megapascals, and surface hardness is measured between 65 and 75 Rockwell C. The acoustic design of Ferodo pads reduces brake noise by up to 30 percent and complies fully with ECE R90 standards. The average service life of original Ferodo pads ranges from 30,000 to 50,000 kilometers, depending on driving conditions.

Ferodo Woven Lining

Woven roll brake lining is manufactured using reinforced fibers and heat-resistant yarns, offering a cohesive yet flexible structure. Its typical thickness ranges from 4 to 10 millimeters, with a density between 1.6 and 2.2 grams per cubic centimeter. The coefficient of friction is measured between 0.35 and 0.45 in dry conditions and 0.30 to 0.38 when wet. It withstands thermal exposure up to 480 degrees Celsius without deformation under stress. The wear rate is reported to be less than 0.06 millimeters per 1,000 kilometers under standard industrial conditions.

The woven structure allows high flexibility and adaptability to uneven brake surfaces. Tensile strength ranges from 120 to 160 megapascals, and surface hardness is rated between 60 and 75 Rockwell C. The layered spiral weave pattern helps evenly distribute applied forces across the entire contact surface. This lining is ideal for industrial brake systems exposed to vibration or intermittent motion. Its estimated service life is up to 95,000 braking cycles under intermittent operation.

M8 fully threaded rod

M8 fully threaded rod in the diameter of M8 mm to M12 mm has maximum industrial use. A metric screw is actually similar to a fully threaded rod that is produced in iron, steel or stainless steel grades. Galvanized iron or stainless steel metric screws are widely used in utility and construction industries. M8 fully threaded rod are produced in lengths of 1, 2 and 3 meters depending on the diameter of the wire. In low diameters such as 8 mm, it is often not possible to produce galvanized metric screws longer than 1 meter, because during gearing the screw, its long length causes warping or bending in the screw. However, it is possible to produce 3 meter long galvanized M8 fully threaded rod in larger diameters.

stainless steel threaded rod

Stainless steel threaded rods are available in low diameters with 1 meter length and sometimes in higher diameters up to 3 meters of length. both grades of 304 and 316 of stainless steel threaded rod are available that both have equal mechanical properties however Grade 316 has better resistance against corrosive materials. due to the lower tensile strength of stainless steel compared to carbon steel in most cases Coarse threads are used on the surface of stainless steel threaded rods.
