In the automotive market environment, strict carbon emission regulations and fierce competition jointly lead to rapid changes in the entire automotive supply chain. According to research, for every 10% reduction in the weight of a car, its carbon dioxide emissions can be reduced by 2.45 kg. Therefore, reducing the weight of cars is still a top priority at present.
The effective solution for lightweighting Z is to reduce the weight of the entire vehicle by using lighter components, but there are very strict requirements for the quality of materials. It is necessary to reduce the weight of the vehicle as much as possible while ensuring its strength and safety performance, thereby improving its power performance, reducing fuel consumption, and lowering exhaust pollution.
Plastic has many characteristics such as light weight, corrosion resistance, impact resistance, high specific strength, sound insulation, low cost, and easy processing. It can meet the needs of reducing both vehicle weight and cost, and is beneficial for the safety, comfort, and appearance of the entire vehicle.
In automotive components, the "clutch hydraulic bearing bracket" is a component that can withstand extreme loads. This component plays a role in disconnecting and connecting the engine and gearbox during the car shifting process.
Even shorter vehicle trips may require hundreds of such gear shifts, so OEM components require a tolerance of millions of times and the product needs to withstand an internal pressure of 120 bar. This requires the material to have excellent wear resistance, even at high temperatures.
Through cooperation with Schaeffler Group in Germany, Emans has chosen Grivory HT material for component research and development. This material is a high-performance poly (phthalamide) with ultra-high mechanical strength and heat resistance, which can maintain excellent mechanical strength even in automotive transmissions at temperatures up to 170 ℃.
In addition to material properties, mold design and processing are also particularly critical. Polyphthalamide has an ultra-high melting point of approximately 320 ℃ and can achieve optimal performance at mold temperatures of 140-150 ℃. Material suppliers and first tier suppliers need to go through months of project work and continuous research and development testing before they can obtain OEM manufacturer recognition.
Nowadays, various car models are driving on the streets and alleys of China, all equipped with clutch hydraulic bearing brackets made of Emans materials, which save more than 20% in weight and cost.
2026 March 1st Week VAFEM Product Recommendation
A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of linear motion bearings. Motorized linear slides such as machine slides, X-Y tables, roller tables and some dovetail slides are bearings moved by drive mechanisms. Not all linear slides are motorized, and non-motorized dovetail slides, ball bearing slides and roller slides provide low-friction linear movement for equipment powered by inertia or by hand. All linear slides provide linear motion based on bearings, whether they are ball bearings, dovetail bearings, linear roller bearings, magnetic or fluid bearings. X-Y tables, linear stages, machine slides and other advanced slides use linear motion bearings to provide movement along both X and Y multiple axis.
