Product Description
ISO 9001:2015 & OE Quality
Manufactured by GOS Brake Systems, part number 2.11.043 (Fren Kaliperi - Sol) is an OE-specification heavy-duty commercial vehicle air disc brake caliper engineered for severe-duty trucks, prime movers, buses, and trailers.
Compatible Systems / Vehicles: KNORR, ST7, SAF, JOST, SMB. OEM Cross References: K097530K50, ST7003RC, 3080008850, 03080008800, 03080008801, 05400101950. Actuator Tilt Angle: 0°. Sensor Configuration: Sensörsüz. Mounting Direction: Sol. Vehicle Application: Trailer (Dorse). The caliper body is cast from premium GGG50 (EN-GJS-500-7) nodular ductile iron, delivering exceptional tensile strength (min. 500 N/mm²), superior impact fatigue resistance, and thermal fatigue endurance under extreme braking temperatures. The uniform spherical graphite microstructure prevents micro-fissures and structural fatigue under high mechanical stress.
Precision machining is executed on advanced multi-axis horizontal CNC machining centers in Konya, Turkey. Critical bore dimensions, piston cylinders, guide pin bushings, and internal mechanism recesses are machined to micron-level tolerances, ensuring exact coaxiality, smooth piston operation, and leak-free sealing performance.
Every caliper body undergoes 3D CMM dimensional verification, pressure testing, and anti-corrosion protective coating. Directly exported to professional distributors, fleet operators, and caliper rebuilders across more than 45 countries with guaranteed 100% direct OE fitment.
