Running-in and Initial Assembly Greases
Initial lubrication for running-in of bearings, gears and new components during the first operating hours
Running-in greases and initial assembly compounds for the protection of bearings, gears and mechanical components during the critical first operating hours. The initial running-in period is the highest risk period for adhesive wear — new machined surfaces have microscopic roughness that needs to progressively settle. The running-in grease acts in two phases: (1) Initial protection — protective film during assembly and transport; (2) Running-in film — active lubrication during the first 50–200 operating hours until surfaces reach optimum roughness. Different from anti-seize grease (prevention of seizing in threads) and service grease (continuous lubrication).
Specifications
Custom formulation available
Characteristics
- NLGI 0 / 1 — easy penetration into new surfaces without run-in microchannels
- Smooth running-in additives — accelerate bedding-in without adhesive wear
- Corrosion protection during storage and transport after assembly
- Compatible with subsequent service grease — no intermediate cleaning required
- Sodium soap-free formulation — stable in the presence of residual cutting fluids
Typical applications
- New bearings in rebuilt reducers or repaired motors
- New gears in industrial gearboxes during first service
- CNC spindles and guides after precision bearing replacement
- Pump bearings at first start-up after major maintenance
- New machinery components during the initial warranty period
Sectors
Key advantages
- Captures the client at the most valuable moment — new equipment assembly
- Client who buys running-in grease will likely buy service grease from you too
- Reduces warranty claims for premature wear on new equipment
- Technical differentiating argument when selling to repair workshops
- Perfectly complements anti-seize assembly paste in the same order
