LIN-11GKL Series — Open Long Design Pillow Block Linear Bearing Unit Plastic Sliding
4 bore sizes · Open long housing · Two bearings · Moment resistance + retrofit
🆕 Series Overview
The LIN-11GKL combines the open-slot lateral access of LIN-11GK with the extended two-bearing configuration of LIN-11GL. Correct selection when both retrofit access (no shaft removal) and moment-load resistance (two-bearing span) are simultaneously required.
Available in 4 bore sizes from 16 mm to 30 mm. The two internal LIN-11RK open-type bearings separated by a spacer provide greater pitching and yawing stiffness than a single LIN-11GK. Both membranes replaceable in situ without shaft removal.
⚙ Key Design Features
Open Slot + Long Housing
Lateral access via open slot PLUS moment resistance from two-bearing span — most capable retrofit pillow block in LIN range.
Two Open Bearings
Two LIN-11RK bearings in single long housing. Both replaceable in situ without shaft removal.
4 Bore Sizes
16–30 mm — main diameters where combined retrofit access and moment resistance are simultaneously required.
Moment Load Resistance
Extended bearing span resists pitching and yawing from offset loads.
Dry Running
Two LIN-11RK membranes. No lubrication. Maintenance-free. Food-grade and washdown properties apply.
Full In-Situ Service
Replace either or both internal bearings without shaft removal.

ⓘ D H7 = housing bore. All dimensions in mm. Load ratings lower than closed LIN-11GL due to open slot. Use LIN-11GKL-specific values.

🔭 Materials & Performance Data
The LIN sliding membrane is a proprietary high-performance plastic with density 1.48 g/cm³ and kinetic friction coefficient 0.05–0.15 against steel (dry). Max PV value (dry) 0.4 N/mm²·m/s, continuous temperature −50°C to +90°C, short-term peak +120°C. Tensile strength 75 MPa (ISO 527), compressive strength 60 MPa, elastic modulus 2,400 MPa, Rockwell hardness HRR 107. The spiral groove pattern on the membrane bore expels contaminants axially rather than allowing accumulation — the key advantage over ball linear bearings in dusty environments. The aluminium housing is anodised for corrosion resistance.
Max PV (Dry)
0.4 N/mm²·m/s. Kinetic friction 0.05–0.15 against steel without lubrication. Higher PV possible with lubrication.
Temperature Range
Continuous −50°C to +90°C. Short-term peak +120°C. Cold-start capable at −50°C without special preparation.
No Lubrication Required
Dry-running design suitable for food, pharmaceutical, and medical applications where lubricant contamination is prohibited.
Chemical Resistance
Resistant to alkaline detergents, dilute acids, mineral oils, and common industrial solvents. Washable with food-industry sanitisers.
🏭 Typical Applications
Retrofit with Moment Loads
Replacing worn closed pillow blocks where payload creates moment loads AND shaft removal is not possible.
Cantilevered Retrofit Applications
Retrofit of cantilevered conveyor guides and offset-load mechanisms where both span and lateral access are required.
Long-Stroke Retrofit Axes
Replacing bearings on long-stroke axes where both stroke demands long span and maintenance prevents shaft removal.
High-Value Machinery
Production machinery where stopping for shaft removal is very costly — LIN-11GKL allows replacement during brief micro-stops.
🔧 Installation & Maintenance
🔎 Lateral Mounting
Slide long housing onto shaft with slot aligned. Rotate so slot faces low-load direction, bolt to frame. Verify both internal bores align with shaft before tightening.
🔧 Load Orientation
Open slot must face away from primary radial load — both internal bearings open on same side. Critical for bearing life.
📈 Load Check
Ratings lower than closed LIN-11GL due to open slot. Use LIN-11GKL table values only.
✅ In-Situ Replacement
Slide housing off shaft laterally, access each bearing position, press out worn LIN-11RK membrane, press in new, slide housing back.
🔎 Selection Guide
Select LIN-11GKL only when BOTH conditions are present: shaft cannot be removed AND moment loads require long housing span.
①
Confirm Environment
Confirm BOTH: shaft cannot be removed AND moment loads require two-bearing span. If only one condition, a simpler model applies.
②
Select Bore & Type
Match bore to shaft. Verify long housing L and W fit machine frame. Plan open-slot orientation to face low-load direction.
③
Verify Load & PV
Apply LIN-11GKL ratings — lower than LIN-11GL. Calculate moment load reactions against individual bearing rating.
