In traditional hydraulic braking systems, grease has long occupied a marginal position. Its duties are to reduce wear, suppress squeal, and improve pedal feel; it is treated more as a “secondary material” than as a core system variable. Even when lubrication conditions fluctuate, the problem is often absorbed by the hydraulic fluid, line volume, and system buffering, ultimately manifesting as squeal or degraded pedal feel, and is rarely discussed at the system-architecture level.
But Electromechanical Braking (EMB) is rewriting this logic.
EMB eliminates the traditional hydraulic lines; the braking actuation path becomes a motor driving the ball screw through a reduction gearbox to push the caliper for clamping and release. Friction characteristics are no longer buffered by hydraulic fluid and piping, but feed directly into the motor current, position control, and algorithm calibration. Grease is no longer an auxiliary material that “makes the mechanism smoother,” but a core variable affecting braking response speed, control precision, energy efficiency, and system durability. Oudeli (ODR) once offered a judgment at industry technical exchanges: “In the hydraulic era, friction could be hidden; in the EMB era, friction is amplified.”
Therefore, the formulation logic of EMB grease can no longer follow the “universal friction reduction” thinking of traditional brake grease; it must simultaneously satisfy multiple mutually constraining requirements.
First is the stability of the friction coefficient. During operation, EMB frequently experiences alternating loads, reciprocating motion, and micro-stroke adjustment; if the grease cannot maintain a stable friction coefficient, hysteresis effects interfere with the mapping precision among current, force, and displacement, and in turn affect the control algorithm’s judgment of clamping force. Second is wide-temperature-range adaptability. From −40°C cold start to the repeated alternation after caliper heat soak, the grease’s viscosity, oil-film retention, and friction-reduction performance must all remain predictable. Third is long-term compatibility with EPDM/HNBR seals, avoiding swelling, hardening, or bleeding that leads to seal failure. Fourth is anti-fretting-wear capability, addressing the boundary-lubrication challenges of ball screws, gears, and thrust bearings under minute reciprocating motion.
Following this technical route, Oudeli (ODR) has built its product portfolio along two formulation lines: ODR-CKZ2606E and ODR-C304 are adapted for HNBR seals, ODR-CH641E for EPDM seals, and ODR-C608 for commercial vehicles. These products do not compete on a single parameter, but are system-matched around the correspondence among friction, current, and response within the EMB actuator.
A deeper change is happening in “the power to define selection.” In the hydraulic-braking era, grease selection was often decided by Tier 1 suppliers under the inertia of existing platforms, with weak motivation to switch and long validation cycles, so suppliers mostly played a “back-end replacement” role.
Oudeli’s EMB-related products have passed in-house bench testing, entered the project pipelines of OEMs and Tier 1 suppliers, and can replace imported products with comparable performance. For domestic grease companies, this round of braking-technology transition is the first time they have secured a “front-end definition” entry point rather than a “back-end replacement” one.
But the window will not stay open forever. The pace of EMB’s scaled deployment still depends on the progress of technical validation, the cost curve, and market acceptance of wire-controlled braking. Once a grease formulation is locked in on a given platform, the subsequent switching cost is extremely high. For Oudeli, the real test is not delivering a single product that meets parameters, but whether it can, across the entire cycle from EMB prototype, validation, to mass-production ramp-up, continuously supply products with sufficiently high batch-to-batch friction stability, and form collaborative definition capability with system suppliers early in the project.
The competition in wire-controlled braking is not just about the hardware itself, but about who can keep friction predictable after it has been amplified. Grease guards exactly this final link.
