LN-11GK open plastic pillow-block unit from the LIN plastic linear-bearing family. Designed for quiet, corrosion-resistant dry running; exact dimensions and load data remain model specific.
The open pillow block is designed around a supported-shaft layout, leaving clearance for the support rail beneath the shaft. The open housing leaves room for a supported shaft rail, making the unit useful on long spans where an unsupported round shaft would deflect too much.
Supported-rail geometry can reduce shaft deflection, while the polymer continues to work as a dry sliding surface. Its catalogue friction band on steel is 0.05–0.15. For thermal screening, keep steady duty within -50/+90 °C. The +120 °C upper figure belongs to brief exposure, not continuous operation.

Data boundary: The figures above are published family properties. Exact dimensions, housing fits and load values for LN-11GK stay model specific and should come from the selected catalogue row.
Open pillow blocks are designed for rail-supported shafts, a common architecture in long travel systems where the shaft must be supported along its length to control deflection.
For LN-11GK, corrosion resistance and lubricant-free travel can simplify machine housekeeping. The catalogue also notes that the LIN material can be cleaned with disinfecting solution, which is useful context for equipment where oil migration would be undesirable.
An open block should be selected together with the supported rail. Shaft diameter, support profile, centre height and underside clearance all need to work as one assembly.
After the geometry is identified, compare the real duty with the dry-running material limits. Record load, sliding speed, stroke, shaft finish and operating temperature in the RFQ so LN-11GK is checked as a system rather than as a bore-size lookup.
For open blocks, verify that the supported shaft rail remains centred in the housing slot across the entire travel. Clean debris from the open underside during routine inspection.
This family does not depend on scheduled grease replenishment. Inspection should instead look for abnormal clearance, embedded abrasive particles, heat and uneven wear; those symptoms often point to shaft or alignment issues around the LN-11GK installation.
Send the LN-11GK model if known, shaft size, quantity, mounting dimensions and duty conditions to sales@netherlandsdrive.com. Ever Power Netherlands Branch will use the supplied catalogue family as the technical reference for selection.
