🆕 Series Overview

The LIN-01RF adds a round flange to the LIN-01R cylindrical housing. The precision-ground flange face registers against the housing shoulder for positive axial location without snap rings or adhesive. Pull out axially, replace membrane if worn, push in until flange seats.

The round flange allows clocking to any angle before bolting. Dynamic load ratings are identical to LIN-01R for the same bore — the flange adds axial retention without reducing radial load capacity.

⚙ Key Design Features

📺

Round Flange Design

Flange face registers against housing shoulder for positive axial location. No snap rings or adhesive required.

📈

Full LIN-01R Load Ratings

Dynamic and static ratings identical to LIN-01R for same bore.

⚙

Any Clocking Angle

Round flange rotates to any angle before bolting — useful for aligning housing features.

🔧

Rapid Replacement

Pull axially, replace membrane, reinstall — faster than snap-ring or interference-fit retention.

🛣

Anodised Aluminium

Corrosion-resistant. Compatible with food-grade cleaning agents.

✅

Replaceable Membrane

LIN-01 membrane replaced independently of housing and flange body.

🔭 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

🍽

Food Processing Flanged Mounts

Flanged bearings in filling machines allow replacement from one side without removing the shaft.

💊

Medical Device Stages

Flanged bearings in analytical and diagnostic systems provide precise axial location and rapid membrane replacement.

⚙

Automation Equipment

Pick-and-place heads and conveyor guides where flange simplifies housing design by eliminating retention hardware.

📈

Linear Actuators

Flanged bearing mounts on actuator guide rods provide positive end-stop location without separate retaining rings.

LIN-01RF in application environment

🔧 Installation & Maintenance

🔎 Housing Counterbore

Machine counterbore to accept flange thickness ts. Bolt circle must match d3. Flange face square to bore axis within 0.02 mm.

🔧 Bolt Torque

Tighten bolts in cross pattern to 30–50% then complete. Sequential tightening distorts flange and shifts bore axis.

🔧 Shaft Specification

h6, Ra 0.8 µm. No hardness requirement.

✅ Membrane Service

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

🔎 Selection Guide

Select LIN-01RF when axial location from one side and rapid replacement are priorities. Round flange allows clocking — useful when feature alignment is required.

①

Confirm Environment

Confirm flanged axial location is required and housing can accommodate counterbore for flange thickness ts.

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

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.
