PLAIN BEARING MATERIALS FOR YOUR SLIDING BEARING APPLICATIONS
FOR MAINTENANCE-FREE SLIDING BEARINGS
Maintenance-free sliding bearing materials contain so-called solid lubricants, which are applied to or incorporated into the carrier material in various ways. These solid lubricants ensure maintenance-free operation over the entire service life of the sliding bearing.
These materials are especially suited for applications where lubrication is not possible, not desired, or difficult to carry out. Depending on the material chosen, they suit a wide range of operating conditions, such as high temperatures, corrosive or dirty environments, and standard applications as well.
SLSP 2
STEEL-SINTERED BRONZE-PTFE COMPOSITE MATERIAL
- Bronze layer sintered onto steel, with a PTFE-based top layer that serves as a dry lubricant
- Self-lubricating through the use of PTFE
- Usable up to +280 °C
SLFE 3002
IRON-NICKEL SINTERED METAL
- Based on sintered iron with embedded, finely distributed dry lubricant, suitable for very high temperatures
- Self-lubricating through the use of graphite
- Usable up to +600 °C (up to 850 °C under exclusion of oxygen)
SLNI 3001
NICKEL SINTERED METAL
- Nickel-based with embedded, finely distributed dry lubricant, resistant to almost all acids, bases, and radioactivity
- Self-lubricating through the use of graphite, only in combination with media lubrication
- Usable up to +450 °C
SLSM 1002
BRONZE SINTERED METAL
- Bronze-based with embedded, finely distributed dry lubricant. Well suited for mechatronic applications.
- Self-lubricating through the use of graphite
- Usable up to +150 °C (up to +350 °C with age hardening/annealing)
SLGL 5001
BRONZE SLIDING BEARING WITH LUBRICATING PLUGS
- Made of bronze or brass with embedded dry lubricating plugs. High dynamic and static load capacity
- Self-lubricating through the use of dry lubricant
- Usable up to +430 °C
FOR LOW-MAINTENANCE SLIDING BEARINGS
Low-maintenance sliding bearing materials have a lubricant reservoir, usually consisting of recesses or holes in the base material, which are filled with a lubricant (usually grease) during installation. This lubricant reserve results in reduced maintenance requirements during operation.
This type of sliding bearing enables lightweight and space-saving bearing designs due to the thin-walled materials used. Depending on the choice of carrier material, these bearings offer good corrosion resistance and show low sensitivity to shock loads or dirt.
SLWB 1R
WRAPPED BRONZE WITH LUBRICATION POCKETS
- Made from rolled tin bronze with rolled-in lubrication pockets that serve as a lubricant reservoir
- Suitable for grease and oil lubrication
- Usable up to +250 °C, depending on the lubricant used
SLWB 1H
WRAPPED BRONZE WITH HOLE DEPOTS
- Made from rolled tin bronze with rolled-in hole depots that serve as a grease reservoir
- Suitable for grease lubrication only
- Usable up to +150 °C
SLSO 2
STEEL-SINTERED BRONZE-POM COMPOSITE MATERIAL
- Bronze layer sintered onto steel, with a POM-based top layer and lubrication pockets serving as a lubricant reservoir
- Suitable for grease and oil lubrication
- Usable up to +130 °C
FOR MAINTENANCE-INTENSIVE SLIDING BEARINGS
Maintenance-intensive sliding bearings (also referred to as requiring maintenance) are standard sliding bearings used for many different applications. Regular lubrication with grease or oil must be observed here.
Depending on the base material, these sliding bearings show good corrosion resistance. By adding extra lubrication grooves, a certain resistance to dirt and improved lubricant distribution can be achieved.
SLPI B
BRONZE SLIDING BEARING
- Sliding bearing made of solid tin bronze, aluminum bronze, or brass, according to DIN ISO 4379 or per customer drawing
- Suitable for grease and oil lubrication
- Max. operating temperature depends on the lubricant used
