LIN-02 Series Sliding Membrane — Standard Open Type Plastic Linear Bearing
8 bore sizes · Open-type slot · Narrower width · Maintenance-free
🆕 Series Overview
The LIN-02 series is an open-type plastic sliding membrane for LIN-02R aluminium housing linear bearings. Compared with LIN-01, the LIN-02 has a narrower width (b1), making it suitable for shorter housings where axial length is constrained. The open-slot configuration enables installation in split housings.
LIN-02 shares the same spiral groove design, dry-running capability, and PV limits as LIN-01. Load ratings are proportionally lower due to the shorter contact length — select LIN-01 where higher load capacity is required within the same bore size.

⚙ Key Design Features
Spiral Groove Expulsion
Same inclined groove design as LIN-01 — dust expelled axially to prevent contamination build-up at the shaft contact.
Narrower Width
Shorter b1 than LIN-01 for same bore — suitable for space-constrained housings.
Open Slot
Open-slot construction enables lateral shaft installation in split housings and retrofit applications.
Food & Pharma Compatible
Identical material to LIN-01. Approved for food contact, washable with alkaline sanitisers.
−50°C to +90°C
Full operating range identical to LIN-01 series.
Replaceable
Membrane replaced independently of housing, retaining aluminium housing 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 Packaging Lines
Short-stroke conveyors and labelling systems where housing length must be minimised without sacrificing dry-running capability.
Split Housing Assemblies
Applications requiring lateral shaft insertion — open-slot membrane installs without removing shaft end fittings.
Compact Instrument Stages
Diagnostic and surgical instrument guides where LIN-01 length cannot fit within the instrument envelope.
Washdown Environments
Narrow open-slot drains wash water more effectively than LIN-01 in full-immersion washdown duty.

🔧 Installation & Maintenance
🔎 Housing Bore
H7 tolerance. Open slot must align with matching recess in housing to prevent membrane rotating.
🔧 Shaft Specification
h6, Ra 0.8 µm. No hardness requirement — identical to LIN-01.
🔁 Slot Orientation
Orient open slot away from primary load direction — slot interrupts contact area on one side.
📈 Load Check
Lower ratings than LIN-01 due to shorter contact. Verify PV ≤ 0.4 N/mm²·m/s and applied force against load table.
🔎 Selection Guide
Select LIN-02 when housing length is constrained and the reduced load capacity relative to LIN-01 is acceptable, or when a split-housing installation is required.
①
Confirm Environment
Confirm shorter body length or split-housing requirement — the primary reasons for selecting LIN-02 over LIN-01.
②
Select Bore & Type
Match d1 bore to shaft. Verify d2 fits housing H7 bore. Confirm b1 fits available housing depth.
③
Verify Load & PV
LIN-02 ratings are lower than LIN-01 for same bore — check load table. PV ≤ 0.4 N/mm²·m/s.
