Pastes for easy assembly and dismantling
The structure of pastes corresponds in principle to that of greases. However, the share of solid lubricants is clearly higher. Thus a reliable lubricating, parting and corrosion protection effect is ensured even when used under extreme temperature and pressure conditions and aggressive media. Pastes are used at screw threaded connections as well as for pressing in pins and bolts, at gearwheels, chucks, hinges and plain bearings.
Characteristic | Standard | Description |
Press-fit test | Provides information about the lubricating effect of pastes at very high pressure and low sliding speed (relevant for assembly pastes) | |
Thread friction coefficient | DIN 946 | The friction coefficient μ when screws and nuts are tightened is determined on a screw test bench (relevant for screw pastes) |
Breakaway torque | DIN 267-27 | Ratio of the required breakaway torque when loosening the screwed connection to the tightening torque |
Operating temperature | Lubrication: Oil and solid lubricants are effective Separation: After the oil has evaporated, separating effect through solid lubricants |
