Linear Bearings › LIN Plastic Series
LIN-02RTL Series — Square Flange Extended Plastic Linear Bearing LIN-02 Membrane
8 bore sizes · Square flange · Extended body · Highest flanged capacity
🆕 Series Overview
The LIN-02RTL is the highest-capacity square-flange configuration in the LIN family, combining a square flange for torsional resistance with the extended body of the LIN-02 membrane format. Load ratings are the highest available in any LIN flanged bearing for the same bore.
Dynamic load ratings 1,300–17,500 N and static 9,100–122,500 N across 8 bore sizes. The square flange resists bearing rotation under torque loads — the primary selection criterion when an eccentric or offset load creates a turning moment at the bearing mount.

⚙ Key Design Features
Square Flange + Extended Body
Highest load in LIN flanged format. Square flange resists torsional loads. Extended body maximises radial rating.
Highest Capacity Flanged LIN
Dyn 1,300–17,500 N, Sta 9,100–122,500 N — highest ratings across all LIN flanged configurations.
Torsional Resistance
Flat square-flange faces prevent bearing rotation under eccentric or offset loads.
Dry Running
LIN-02 membrane. No lubrication. Replaceable. Food-grade and washdown compatible.
Anodised Housing
Corrosion-resistant aluminium. Suitable for washdown environments.
Replaceable Membrane
Replace LIN-02 membrane when worn. Housing and flange body retained.

🔭 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
Heavy Eccentric Load Mechanisms
Primary bearing for cams and offset tooling where high radial load and torsional constraint are simultaneously required.
High-Load Actuator Guides
Heavy actuator guide bearings in industrial presses where payload creates combined radial and moment loads.
Food Processing Main Drives
Heavy-duty food processing carriages where maximum load and torsional stability are both required.
Precision Manufacturing
Square-flange bearings in heavy grinding and honing slides where flat faces serve as precision datum references.

🔧 Installation & Maintenance
🔎 Square Counterbore
Machine square counterbore for flange width k and thickness ts. All four flat faces square to bore within 0.02 mm.
🔧 Bolt Torque
Cross-pattern tightening. Square faces provide torsional resistance even at moderate torque.
🔧 Shaft Specification
h6, Ra 0.8 µm. No hardness requirement.
✅ Membrane Service
Remove bolts, pull axially, press out LIN-02 membrane, press in new. Housing and flange body retained.
🔎 Selection Guide
Select LIN-02RTL when maximum load AND torsional resistance are both required. If torsional loads absent and round-flange clocking is advantageous, use LIN-02RFL.
①
Confirm Environment
Confirm both high load AND torsional constraint required simultaneously — primary trigger over LIN-02RFL.
②
Select Bore & Type
Match d1 bore to shaft. Verify housing square counterbore matches flange dimensions k and ts.
③
Verify Load & PV
Verify F ≤ dynamic rating. Highest LIN flanged ratings — if still insufficient, contact GBC for custom sizing.
