LIN-02RFL Series — Round Flange Extended Plastic Linear Bearing LIN-02 Membrane
8 bore sizes · Round flange · Extended body · Highest round-flange capacity
🆕 Series Overview
The LIN-02RFL combines a round flange for axial location with an extended body using the LIN-02 membrane in a longer format. Load ratings exceed those of the standard LIN-01RF — making LIN-02RFL the highest-capacity round-flange option in the LIN family.
Dynamic load ratings 1,300–17,500 N and static 9,100–122,500 N across 8 bore sizes. Round flange provides positive axial location and allows clocking to any angle before bolting. LIN-02 membrane replaceable independently.

⚙ Key Design Features
Round Flange + Extended Body
Combines positive axial location with extended body for higher load than standard LIN-01RF.
Highest Capacity Round Flange
1,300–17,500 N dynamic — highest load ratings in the LIN round-flange format.
Any Clocking Angle
Round flange rotates freely before bolting — clock to align housing features.
Dry Running
LIN-02 membrane. No lubrication. Replaceable. Food-grade compatible.
Anodised Housing
Corrosion-resistant. Compatible with alkaline food-industry cleaners.
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
High-Load Food Equipment
Heavy-duty filling, portioning, and slicing machines where round flange mounts to frame and load exceeds LIN-01RF capacity.
Industrial Medical Equipment
Large-format medical imaging and therapeutic device stages requiring high-load dry-running with flanged mounting.
Heavy Automation
Pick-and-place and palletising robot guide bearings where flange mounting simplifies frame design.
Packaging Machine Drives
Primary carriage bearings where payload mass pushes LIN-01RF load ratings to their limit.

🔧 Installation & Maintenance
🔎 Housing Counterbore
Counterbore to accept flange thickness ts. Bolt circle must match d3. Flange face square to bore within 0.02 mm.
🔧 Bolt Torque
Cross-pattern tightening to prevent flange distortion.
🔧 Shaft Specification
h6, Ra 0.8 µm. No hardness requirement.
✅ Membrane Service
Remove bolts, pull axially, press out LIN-02 membrane, press in new, reinstall.
🔎 Selection Guide
Select LIN-02RFL when load exceeds LIN-01RF capacity and round-flange mounting is required.
①
Confirm Environment
Confirm round-flange mounting is required and load exceeds LIN-01RF capacity.
②
Select Bore & Type
Match d1 bore to shaft. Verify d2h7 fits H7 bore. Confirm flange d3 bolt circle matches housing pattern.
③
Verify Load & PV
Verify F ≤ dynamic rating from LIN-02RFL table. Ratings are higher than LIN-01RF for same bore.
