LIN-01RT Series — Square Flange Plastic Linear Bearing with Aluminum Housing

🆕 Series Overview

The LIN-01RT uses a square flange on the aluminium housing. Unlike the round flange of LIN-01RF, the square flange provides four bolt points at 90° intervals and its flat faces square against the housing wall, providing torsional resistance without relying solely on bolt friction.

LIN-01RT is preferred when a torque load component acts on the bearing — for example, where an eccentric or offset load creates a turning moment at the bearing mount. Load ratings are identical to LIN-01R. All dry-running and membrane-replacement features are shared with LIN-01RF.

⚙ Key Design Features

📺

Square Flange Design

Four bolt points at 90° with flat faces — resists bearing rotation under torsional loads.

📈

Full LIN-01R Load Ratings

Dynamic and static ratings identical to LIN-01R — square flange adds rotational constraint only.

🔎

Flat Reference Faces

Square flange faces serve as datum surfaces during assembly, simplifying alignment.

🔧

Dry Running

No lubrication. Replaceable LIN-01 membrane. Anodised housing for washdown.

🛣

Chemical Resistance

Suitable for food, pharmaceutical, and industrial wash-down applications.

✅

Easy Service

Remove four bolts, pull axially, replace membrane, reinstall.

🔭 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

⚙

Eccentric Load Mechanisms

Bearings supporting eccentric cams or offset tooling plates that generate a turning moment at the bearing mount.

📈

Torsionally Loaded Actuators

Linear actuators with side loads where bearing rotation would compromise guidance accuracy.

🔎

Precision Machinery

Square-flange bearings in grinding and inspection equipment where flat faces are used as datum references.

💊

Medical & Analytical Equipment

Instrument stages where the square flange integrates as both bearing mount and structural reference.

🔧 Installation & Maintenance

🔎 Housing Counterbore

Machine square counterbore to match flange width k and thickness ts. All four faces square to bore axis within 0.02 mm.

🔧 Bolt Torque

Tighten in cross pattern. Square faces provide torsional resistance even at low bolt torque.

🔧 Shaft Specification

h6, Ra 0.8 µm. No hardness requirement.

✅ Membrane Service

Remove four bolts, pull axially, press out membrane, press in new LIN-01 membrane, reinstall.

🔎 Selection Guide

Select LIN-01RT when a torque load component is present or square flange faces are required as datums. If only axial location with no torsional load, LIN-01RF is simpler.

①

Confirm Environment

Confirm torsional load is present or square flange faces are required as assembly datums.

②

Select Bore & Type

Match d1 bore to shaft. Verify housing square counterbore accepts flange dimensions k and ts.

③

Verify Load & PV

Load ratings identical to LIN-01R. Verify F ≤ dynamic rating at P = 5 MPa.

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.
