Precision Engineering: How Stellox Power Steering Pump Design Affects Rack Life

The tie rod end is more than a simple limited-life component; it is a critical safety node. Stellox uses a two-stage heat treatment for the spherical pin: The surface layer reaches a hardness of 58-62 HRC for wear resistance, while the core remains ductile to withstand impact loads without brittle fracture. The PTFE-based polymer insert ... Safety Geometry: Why Pin Hardness and Dust Boot Elasticity are Critical in Stellox Tie Rod Ends

The cabin filter is no longer an "invisible" spare part. Today, drivers are increasingly paying attention to the quality of air inside the vehicle — especially in megacities and during the plant flowering season. For service shops, this is an opportunity to increase the average ticket by offering a filter that matches actual operating conditions. ... Cabin Filters: From Dust to Allergens — How to Choose a Solution Based on Customer Needs

Modern injection systems impose strict requirements on fuel purity. In diesel Common Rail and petrol GDI systems, the permissible size of mechanical impurities is no more than 4 microns. Exceeding this threshold leads to rapid wear of injectors and the high-pressure fuel pump. Two Filtration Stages Preliminary filtration: A strainer filter in the fuel pump ... Fuel Filters: Selection Specifics for Petrol and Diesel Engines
