Square FlangeExtended BodyHighest Flanged CapacityTorsional Resistance

🆕 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.

LIN series plastic linear bearings overview

❓ Frequently Asked Questions

▶ What is the difference between LIN-01R and LIN-02R bearings?

LIN-01R uses the LIN-01 standard membrane for higher load capacity. LIN-02R uses the narrower LIN-02 membrane in a shorter housing body. Both use identical aluminium housings; the membrane type determines load rating and body length.

▶ Can the membrane be replaced without replacing the housing?

Yes — this is the key service advantage. When the membrane wears and shaft play develops, only the membrane is replaced. The aluminium housing is retained. This significantly reduces replacement cost and maintenance time compared with ball linear bearing units.

▶ What housing bore tolerance is required?

H7 tolerance. Press the bearing into a H7-tolerance bore. Do not use adhesive — the membrane must remain free to flex slightly under load, and the housing must be removable for membrane replacement.

▶ Are LIN bearings suitable for vertical shaft applications?

Yes. The dry-running design is unaffected by shaft orientation — no grease migration issue. In vertical applications, the spiral groove assists axial expulsion of particles that might otherwise accumulate at the lower end.

▶ What is the maximum operating speed?

Maximum linear velocity is 1.5 m/s for oscillating motion and 1.1 m/s for continuous linear travel (PV limit 0.4 N/mm²·m/s at P = 5 MPa). For higher speeds, reduce applied load to stay within the PV envelope. Contact GBC for applications above 1 m/s continuous.
