LIN-11GK Series — Open Pillow Block Linear Bearing Unit Plastic Sliding
4 bore sizes · Open slot · Lateral shaft access · Retrofit friendly
🆕 Series Overview
The LIN-11GK is an open-type pillow block with a slot through the top of the housing, allowing the unit to be mounted laterally onto the shaft without removing the shaft. This is the defining advantage for retrofit applications and field replacement on operational machinery.
Available in 4 bore sizes from 16 mm to 30 mm. Open slot reduces supported arc to approximately 240°–270°, so load ratings are lower than closed LIN-11G. Orient housing so open slot faces away from primary load. LIN-11RK open-type bearings are pre-installed.
⚙ Key Design Features
Open Slot Housing
Top-open slot allows lateral mounting onto shaft without shaft removal — essential for retrofit.
Complete Unit
Housing with LIN-11RK open bearing pre-installed. Mount laterally, orient slot, secure.
4 Bore Sizes
16–30 mm — the most common range for retrofit applications in legacy machinery.
Dry Running
LIN-11RK bearing. No lubrication. Maintenance-free. Replaceable in situ.
Anodised Aluminium
Corrosion-resistant for wet and chemically aggressive environments.
In-Situ Replacement
Replace internal bearing without shaft removal — key advantage for installed machinery.
📋 Complete Specification Table
ⓘ D H7 = housing bore diameter. h = shaft bore. All dimensions in mm. Load ratings lower than closed LIN-11G due to open slot.

🔭 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 Ball Bearing Replacement
Replace worn ball pillow blocks during short maintenance stops — LIN-11GK installs without shaft removal.
Continuous-Run Conveyors
Conveyor guide bearings on systems that cannot be stopped long enough for shaft removal.
Inaccessible Shaft Ends
Machinery where shaft ends are embedded in structure or obstructed by adjacent components.
Development & Prototype
Early-stage machinery where bearing positions may need adjustment along the shaft.
🔧 Installation & Maintenance
🔎 Lateral Mounting
Slide housing laterally onto shaft with slot aligned. Rotate so slot faces low-load direction, bolt to frame.
🔧 Load Orientation
Open slot MUST face away from primary radial load. Incorrect orientation significantly reduces bearing life.
📈 Load Check
Ratings lower than closed LIN-11G. Use LIN-11GK-specific ratings from table.
✅ In-Situ Bearing Replacement
Slide housing laterally off shaft, press out LIN-11RK bearing, press in new, slide housing back. No shaft removal needed.
🔎 Selection Guide
Select LIN-11GK specifically when shaft cannot be removed. If shaft can be removed, use LIN-11G for higher load rating.
①
Confirm Environment
Confirm shaft cannot be removed — mandatory criterion for LIN-11GK.
②
Select Bore & Type
Match bore to shaft. Verify housing dimensions fit space. Plan open-slot orientation relative to load.
③
Verify Load & PV
Apply LIN-11GK ratings from table — lower than LIN-11G. Do not substitute closed-housing values.
