LIN-01RK Series — Open Slot Plastic Linear Bearing with Aluminum Housing
8 bore sizes · Open slot · Lateral shaft access · Retrofit friendly
🆕 Series Overview
The LIN-01RK features an open slot running the full length of both the aluminium housing and LIN-01 membrane, allowing lateral installation onto the shaft without removing the shaft from its supports. Critical for retrofit installations and field maintenance on machinery where shaft disassembly is not possible.
The open slot reduces supported contact arc to approximately 270°. Load ratings are correspondingly lower than full-round LIN-01R. Orient the open slot away from the primary load direction to maximise effective contact. All dry-running properties are identical to LIN-01R.
⚙ Key Design Features
Open Slot for Lateral Access
Mounts laterally onto shaft without removing shaft end fittings — the defining advantage for retrofit and field-service.
Complete Unit
Aluminium housing with LIN-01 membrane pre-fitted. Open slot runs full body length.
270° Contact Arc
Open slot reduces supported arc — orient slot away from primary load to maximise load-bearing contact.
Dry Running
No lubrication. Maintenance-free. Replaceable membrane. Food-grade compatible.
Anodised Housing
Corrosion-resistant for wet and chemically aggressive environments.
Field Replaceable
Replace bearing in situ without shaft removal — the key service benefit for installed machinery.

🔭 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
Retrofit Maintenance
Replacing worn linear bearings on operational machinery without shaft removal — reduces downtime from hours to minutes.
Split-Housing Assemblies
Machines with split housings that open laterally — LIN-01RK matches the split-housing maintenance philosophy.
Continuous-Run Conveyors
Guide bearings on shafts that cannot be stopped long enough for shaft removal during replacement.
Prototype Machinery
Early-stage machines where bearing positions may need adjustment — open-slot bearings reposition along shaft without full disassembly.
🔧 Installation & Maintenance
🔎 Lateral Installation
Slide bearing laterally onto shaft with slot aligned. Once on shaft, rotate so slot faces low-load direction before securing housing.
🔧 Load Orientation
Open slot MUST face away from primary radial load. Incorrect orientation reduces life significantly.
📈 Load Check
Ratings lower than LIN-01R due to reduced contact arc. Use open-slot load values in table — do not use LIN-01R values.
✅ In-Situ Service
Slide bearing off shaft laterally, press out membrane, press in new LIN-01 membrane, replace. No shaft removal needed.
🔎 Selection Guide
Select LIN-01RK specifically for retrofit or field-service where shaft cannot be removed. If shaft can be removed, use LIN-01R for higher load rating.
①
Confirm Environment
Confirm shaft cannot be removed — this is the primary criterion for LIN-01RK.
②
Select Bore & Type
Match d1 bore to shaft. Verify d2h7 fits H7 bore. Plan open-slot orientation relative to primary load.
③
Verify Load & PV
Apply open-slot load ratings from table. Lower than LIN-01R — do not substitute closed-housing values.
