DryLin® - Glides instead of rolling!
DryLin® is a product range of maintenance-free and lubricant-free linear bearings in four different main categories. Besides the freedom from maintenance, the main features include ruggedness and the insensitivity to dirt, water, chemicals, heat or impacts.
Recirculating ball bearing

Comparison of noise development
Maintenance-free
Dry operation
Resistant to dirt, dust and humidity
Weight reduction
For short-stroke applications
Self-lubricating
Very quiet run
Wear resistant
Corrosion resistant
Insensitive to impacts and vibrations
Low coefficients of friction
High static load capacity
High speeds and accelerations possible
Low surface pressure
DryLin® linear bearings operate on glide pads unlike the common recirculating ball bearing systems. Thus an essentially larger contact surface becomes available resulting in essentially lower surface pressure. The resultant advantages are:
The application of non-hardened shafts is possible.
Even non-metallic counter-partners are usable
A galling is completely excluded.
Dry run, without lubrication
DryLin® linear bearing systems are designed for the dry operation. Your applications are thereby protected against soiling by grease or oil. Even the application under coarse dirt and sand is possible. Particles are repelled from the contact surface by the movement itself. Here the front side of the gliders works like a wiper. The contact surface remains clean.
No minimum stroke lengths
In contrast to recirculating ball bearings, the DryLin® bearings operate independent of the travel length and do not pose any conditions on the minimum stroke length. Even applications with extremely short strokes are no problem for the DryLin® linear bearings.
Low noise
The quiet run is also based on the feature of gliding in contrast to rolling. There is no mechanical rolling up of hard gliding partner and no ball collisions that cause loud noises. The gliding motion is extremely low noise and only a light friction noise is audible.
