LIN-02R Series — Standard Cylindrical Plastic Linear Bearing LIN-02 Membrane
8 bore sizes · LIN-02 membrane · Compact body · Dry running
🆕 Series Overview
The LIN-02R is a cylindrical plastic linear bearing using the LIN-02 open-type sliding membrane in an anodised aluminium housing. The LIN-02 membrane is narrower than LIN-01, giving a shorter body and lower load ratings — the correct selection when axial space is constrained.
Dynamic load ratings 780–10,500 N and static 5,460–73,500 N across 8 bore sizes (10–50 mm). All dry-running, food-grade, and maintenance-free properties of the LIN series are retained. Membrane replaceable independently of housing.
⚙ Key Design Features
Compact Body
Shorter body length than LIN-01R for same bore — suited for space-constrained actuators.
LIN-02 Membrane
Narrow open-type membrane. Replaceable independently. Same dry-running and food-grade properties.
Dry Running
No lubrication. Maintenance-free. Compatible with food-industry washdown.
Anodised Housing
Corrosion-resistant. Suitable for wet and chemically aggressive environments.
−50°C to +90°C
Full LIN temperature range.
Replaceable Membrane
LIN-02 membrane replaced when worn — housing retained for multiple service cycles.

🔭 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
Compact Medical Instruments
Short-stroke laboratory automation, pipette dispensers, and compact diagnostic systems.
Tight-Pitch Linear Stages
Multi-axis stages where LIN-01R length would interfere with adjacent axes.
Mini Food Equipment
Small-format portioning and filling heads requiring food-grade dry running in restricted axial space.
Consumer Electronics
Scanner, printer, and optical disc mechanism guides requiring dry running and low particulate generation.
🔧 Installation & Maintenance
🔎 Housing Bore
H7 tolerance. Press LIN-02R into bore using press tool on outer housing end face. Do not use adhesive.
🔧 Shaft Specification
h6, Ra 0.8 µm. No hardness requirement.
📈 Load Check
LIN-02R ratings lower than LIN-01R for same bore. Verify applied load against specification table.
✅ Membrane Service
Press out worn LIN-02 membrane, press in new LIN-02 membrane. Housing retained.
🔎 Selection Guide
Select LIN-02R when housing depth is shorter than LIN-01R body length and reduced load rating is acceptable.
①
Confirm Environment
Confirm LIN-02R shorter body is required and reduced load rating is acceptable.
②
Select Bore & Type
Match d1 bore to shaft. Verify d2h7 fits H7 bore. Confirm body B fits housing depth.
③
Verify Load & PV
Verify F ≤ dynamic rating from LIN-02R table. Ratings are lower than LIN-01R — do not use LIN-01R values.
