Clutch Pressure Plates

Name: Clutch Pressure Plates | Transmission Grip & Release Units - Frigate
Price: 249.00 USD
Availability: InStock

Clamping force from the clutch pressure plates must evenly press the clutch disc against the flywheel surface. Uneven force causes clutch slip and uneven wear on the flywheel.

Clamping Force/Pressure Load

2,000–6,000 N (OEM) / 4,000–10,000 N (performance)

Clutch Disc Diameter Compatibility

200–350 mm (matched to flywheel)

Flywheel Bolt Pattern

6–9 bolts (M8–M12); PCD 200–300 mm

Overall Outer Diameter

250–400 mm (±0.2 mm tolerance)

Cover Material

Cast Steel (GGG60) / Billet Steel (4340) / Aluminum (for racing)

Product Description

Diaphragm springs control load distribution with precision to ensure proper flywheel engagement. Spring finger stiffness and material properties affect how pressure transfers to the flywheel. Machined surfaces ensure consistent contact with the flywheel for smooth power transfer.

Diaphragm Spring Design/Material

Single/Belleville spring; High-carbon steel (SAE 5160)

Friction Face/Pressure Ring Material

Hardened steel (HRC 45–50) / Ceramic-coated (high-temp)

Release Bearing Contact Diameter

50–100 mm (±0.1 mm; compatible with OEM bearings)

Weight

5–15 kg (material-dependent)

Certification Standards

ISO 9001:2015, IATF 16949, SAE J1809

Technical Advantages

Heat generated during clutch engagement transfers to both the clutch pressure plates and flywheel. Materials must resist thermal deformation to maintain clutch-to-flywheel contact geometry. Steel alloys with stable microstructure at high temperatures prevent distortion of the flywheel interface. Ventilation features in the pressure plate improve cooling of the flywheel contact area. Controlled heat treatment prevents warping of both components during repeated thermal cycles.

Repeated clutch use causes cyclic stresses in the pressure plate and flywheel interface. Stress concentrations on spring fingers are minimized to protect the flywheel surface from uneven load. Finite element analysis optimizes spring design to reduce impact on the flywheel. Shot peening enhances fatigue strength, preserving spring function and flywheel engagement. Proper stress management extends the service life of both the clutch pressure plates and flywheel.

Industry Applications

Automotive Powertrains

Transmit torque between engine and transmission, enabling controlled engagement and disengagement for smooth vehicle acceleration and gear shifting.

Heavy-Duty Commercial Vehicles

Withstand high torque loads and frequent engagement cycles in trucks, buses, and construction machinery requiring durable clutch pressure systems.

Agricultural Machinery

Provide reliable torque transfer in tractors and harvesters, handling variable loads and harsh operating environments with precise clutch control.

Industrial Equipment

Enable controlled power transmission in manufacturing machinery and presses, ensuring accurate start-stop operations and load regulation.

Motorcycles and Two-Wheelers

Facilitate compact torque transmission systems that allow rapid clutch engagement and disengagement for responsive gear changes.

Marine Propulsion Systems

Transfer engine power to propellers with resistance to corrosion and thermal cycling in marine environments requiring robust clutch components.

Dimensional Accuracy and Interface Compatibility

Precise dimensions ensure perfect alignment between the pressure plate, clutch disc, and flywheel, ensuring optimal performance. Bore concentricity and flatness maintain flywheel concentric rotation during clutch operation. Tight machining tolerances prevent vibrations caused by misalignment of the flywheel and clutch pressure plates.

Corrosion on clutch pressure plates and flywheels degrades the friction interface and structural integrity. Protective coatings resist environmental damage without affecting clutch-to-flywheel engagement. Surface treatments prevent oxidation that can cause uneven wear on the flywheel contact area.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure the precision of pressure plate spring tension?

Frigate uses advanced finite element analysis to design diaphragm springs with optimal tension profiles. This process minimizes stress concentrations and ensures consistent clamping force during operation. Each spring undergoes precise manufacturing and heat treatment to maintain its mechanical properties. Quality control checks verify that spring tension matches design specifications before assembly.

What material treatments does Frigate apply to improve thermal resistance?

Frigate applies controlled quenching and tempering heat treatments to alloy steel pressure plates. These treatments enhance the material’s hardness and reduce thermal deformation risks under high clutch temperatures. Surface coatings are applied to enhance corrosion resistance and improve thermal conductivity. This combination helps maintain dimensional stability and clutch performance over time.

How does Frigate address the challenge of balancing pressure plate and flywheel tolerances?

Frigate maintains tight machining tolerances on pressure plates to ensure accurate fit with flywheels. Precision grinding and finishing processes control flatness and concentricity within strict limits. This alignment prevents vibration and uneven wear during clutch operation. Continuous inspection guarantees compatibility and smooth engagement in the clutch assembly.

What testing methods does Frigate use to verify fatigue life of pressure plate springs?

Frigate performs cyclic load testing that simulates millions of clutch engagement cycles. This identifies potential fatigue failures before production release. Material samples undergo microstructural analysis to detect stress risers or defects. These tests ensure the springs retain clamping force and reliability over their expected lifespan.

How does Frigate optimize pressure plate design for various engine torque requirements?

Frigate customizes diaphragm spring thickness, diameter, and finger count based on engine torque data. This allows precise control of clamping force to handle different power outputs. CAD and simulation tools predict force distribution and engagement smoothness before manufacturing. This engineering approach reduces the risk of clutch slip and enhances drivetrain efficiency.
