Metelli / Metelli Group aftermarket automotive components: series 24-XXXX mechanical water pumps, switchable water pumps, series 22-XXXX HybriX brake pads, hydraulic brake and clutch cylinders, and induction-hardened CV joints.

Metelli Mechanical Engine Cooling Water Pumps

Metelli mechanical water pumps series 24-XXXX feature heavy-duty integral bearings and silicon carbide mechanical face seals. The precision forged aluminum housing withstands severe cooling cavitation and thermal stress. Assemblies maintain stable coolant circulation under demanding fleet cycles.

Heavy-duty dual-row integral bearing withstands extreme radial belt tension
Silicon carbide mechanical face seal prevents coolant leakage under pressure
Corrosion-resistant metal impeller delivers optimized hydrodynamic coolant flow
Precision machined mounting flange with pre-cut high-performance gasket included

Metelli Switchable and Auxiliary Electric Water Pumps

Metelli switchable water pumps with electromagnetic actuation and 25-XXXX auxiliary electric pumps optimize thermal warm-up cycles. An integrated fail-safe mechanism returns the sliding shroud to full flow on power loss. The unit cuts fuel consumption and stabilizes cylinder head temperatures.

Electromagnetic control shroud manages coolant flow during cold start-up cycle
Patented fail-safe mechanism prevents engine overheating if power is interrupted
Brushless DC electric motor on auxiliary pump delivers durable thermal control
Weatherproof automotive connector housing resists road debris and moisture brine

Metelli HybriX Brake Pads and Discs

Metelli series 22-XXXX brake pads utilize advanced copper-free HybriX friction formulation with full ECE R90 homologation. Multi-layer rubber-steel anti-noise shims dampen high-frequency vibration and eliminate brake squeal. The friction material maintains consistent friction coefficient when hot.

Copper-free HybriX composite friction mix minimizes rotor grooving and brake dust
ECE R90 homologation verifies reliable stopping distance and thermal stability
Multi-layer vulcanized rubber-steel shims absorb caliper vibration frequencies
Integrated electrical and acoustic wear indicator pins included where specified

Metelli Brake Master and Wheel Cylinders

Metelli series 05-XXXX brake master cylinders and 04-XXXX wheel cylinders are precision machined from anodized aluminum and ductile iron. Micro-honed bore surfaces ensure smooth piston glide and leak-free pressure containment. Assemblies deliver instant hydraulic pressure buildup during hard stops.

Anodized internal bore finish protects against aggressive moisture pitting
Diamond micro-honing ensures smooth piston actuation and extended seal life
High-grade EPDM rubber seals remain resilient in heavy-duty DOT4 brake fluids
Calibrated bleeder valves and fluid return ports ensure simple circuit purge

Metelli Clutch Actuators and Concentric Slave Cylinders

Metelli series 56-XXXX concentric slave cylinders and 54-XXXX hydraulic clutch actuators deliver smooth and responsive pedal control. Thermal-resistant EPDM elastomer seals remain stable against aggressive DOT4 hydraulic fluids. The assembly prevents clutch drag and chatter under heavy city traffic.

Integrated concentric layout combines release bearing and hydraulic actuator
Angular contact release bearing withstands heavy diaphragm spring axial thrust
Protective elastomer boot shields piston assembly from clutch lining dust
Quick-connect hydraulic fluid fittings ensure rapid assembly and bubble purge

Metelli CV Joints and Drive Half-Shafts

Metelli series 15-XXXX wheel-side CV joints and 16-XXXX inner tripod joints transmit heavy drive torque without vibration. Precision induction-hardened ball tracks prevent contact fatigue pitting under severe axle loads. The alloy core maintains ductile toughness during sudden torsional shocks.

High-frequency induction hardening provides superior ball track wear resistance
Precision splined interface delivers backlash-free engagement with axle shaft
Tear-resistant thermoplastic boot withstands low temperatures and road debris
Molybdenum disulfide MoS2 extreme-pressure grease sachet included in packaging

Mechanical Engine Water Pumps: Hydrodynamic Profile and Face Seals

Metelli series 24-XXXX water pumps integrate a robust one-piece aluminum housing and an integral double-row bearing assembly. The silicon carbide mechanical face seal prevents fluid weeping during rapid thermal shocks and high engine revolutions.

The hydrodynamic curvature of the metal impeller maintains balanced coolant throughput without inducing cavitation erosion.

Electromagnetic Switchable Water Pumps with Fail-Safe Protection

Switchable water pumps engineered for modern turbo diesel engines feature an axially movable control shroud around the impeller. During initial cold operation, the electromagnetic actuator positions the shroud over the vanes to stop flow and expedite warm-up.

An integrated spring-loaded fail-safe system retracts the shroud automatically if power drops.

Copper-Free HybriX Friction Formulations and ECE R90 Homologation

Metelli series 22-XXXX brake pads utilize advanced copper-free HybriX friction compounds that deliver dependable stopping torque under intense thermal loading. The friction material is hot-pressed and scorched to stabilize deceleration behavior under high operating temperatures.

Bonded multi-layer rubber-steel anti-noise shims isolate caliper vibration.

Precision Brake Hydraulic Actuation: Master and Wheel Cylinders

Series 05-XXXX master cylinders and 04-XXXX wheel cylinders are manufactured from anodized aluminum or ductile iron. Micro-honed cylinder bore walls ensure uniform fluid film retention and prevent premature piston seal wear.

Resilient EPDM synthetic rubber cups withstand extreme temperature swings without losing elasticity or pressure retention.

Concentric Slave Cylinders: Integrated Hydraulic Clutch Control

Concentric slave cylinders series 56-XXXX unify the hydraulic clutch release cylinder and the thrust bearing into a single coaxial component. This direct actuation layout minimizes pedal effort, removes linkage play, and smooths gear engagement.

Protective wiper seals prevent ambient clutch dust from penetrating the internal hydraulic piston bore.

Constant Velocity Joint Technology: Ball Tracks and Tripod Housings

Wheel-side CV joints series 15-XXXX and inner tripod units 16-XXXX transmit dynamic engine torque smoothly at articulation angles up to forty-five degrees. High-frequency induction hardening of the ball grooves produces an wear-resistant deep surface layer.

Durable thermoplastic boots retain extreme-pressure molybdenum grease and deflect flying stones.
