Mounted around the transmission input shaft, the 31258380 Single Port Concentric Hydraulic Clutch Release Bearing combines slave cylinder and release bearing functions in one piece. This layout removes external linkages and forks, creating a shorter and more direct force path inside the bell housing. Mounting points on the outer body match original equipment positions for straightforward installation.
A durable seal protects the bearing contact face during operation. Materials are chosen to handle repeated pressure cycles and the temperatures found inside modern transmission housings. The single-port design keeps the hydraulic circuit simple while still supporting effective system bleeding after fitting.
Core Functions
The 31258380 Single Port Concentric Hydraulic Clutch Release Bearing converts pedal effort into precise axial movement. Fluid enters the single port, expands the piston chamber and drives the bearing forward. This action lifts the pressure-plate fingers and frees the clutch disc for gear selection.
When the pedal returns, residual spring force retracts the piston and bearing so the clutch re-engages smoothly. Even pressure around the full circumference of the diaphragm helps avoid localised wear. The concentric arrangement keeps the force path short and aligned with the input shaft, supporting consistent pedal feel and reliable engagement throughout the service life of the unit.
Purchase Motivation
Distributors and multi-brand workshops stock this reference because it covers a group of high-volume platforms with one part number. Inventory stays simpler when a single SKU meets recurring demand from both passenger cars and light crossover models.
Service teams value the direct installation sequence once the gearbox is removed. The unit seats in the original location, connects via the single hydraulic port and needs only standard bleeding procedures. Accurate dimensions and sealing surfaces reduce the risk of incorrect fitment claims.
Fleet operators running mixed Focus, Mondeo, S-Max and Kuga vehicles gain shorter downtime. A failed release unit can stop a vehicle completely; keeping the 31258380 Single Port Concentric Hydraulic Clutch Release Bearing available allows faster return to service without waiting for alternative codes.
