The LHS12A FONKIN is a high-precision L-type rod end bearing designed for oscillating, rotational, and tilting motion transmission, delivering exceptional durability and reliability for industrial motion systems. Optimized for automotive, construction machinery, agricultural equipment, and packaging machinery, it is a core component for linkage mechanisms requiring low-torque operation and long-term stability.
Inner diameter (d): 12 mm
Outer diameter (D): 26 mm
Width (B): 14 mm
Thread size: M12×1.25
Chamfer: 0.8×45°
Tolerance class: P5 (ISO 492), radial clearance C3
Weight: 0.12 kg
Inner/outer rings: 52100 bearing steel (HRC 60–62), high hardness, wear resistance, and corrosion resistance.
Ball stud: 42CrMo alloy steel, quenched and tempered for high strength and impact resistance.
Cage: Copper alloy (CuSn8), self-lubricating, low friction, and high-temperature resistance.
Seal: Nitrile rubber (NBR), dustproof and grease-retaining.
Forging & annealing: Precise forging of steel blanks, followed by spheroidization annealing to optimize machinability.
Turning & precision machining: CNC turning for dimensional accuracy (±0.01 mm).
Heat treatment: Vacuum quenching + low-temperature tempering for uniform hardness and residual stress reduction.
Grinding & superfinishing: ID/OD grinding (Ra ≤ 0.4 μm) and raceway superfinishing (Ra ≤ 0.1 μm) for minimal friction.
Assembly & inspection: Cleanroom assembly, 100% dimensional and performance testing for quality assurance.
Rated life (L10): 50,000 hours under standard conditions (radial load 5 kN, 25°C, 50 rpm, proper lubrication).
Key factors: Load magnitude, operating speed, temperature, lubrication quality, and alignment accuracy.
Automotive: Steering linkages, suspension components, and transmission systems.
Construction machinery: Hydraulic cylinder linkages, boom connections, and control mechanisms.
Agricultural equipment: Harvesting machine linkages, plow adjusters, and conveyor systems.
Packaging machinery: Pneumatic actuator linkages, swing arms, and precision positioning units.
Adaptation reason: Compact structure, low-torque swivel, and high misalignment tolerance (up to ±15°).
Lubrication cycle: Every 200 operating hours or monthly (whichever comes first).
Recommended grease: Alvania Grease S2 (or equivalent lithium-based grease), 0.5–0.8 g per lubrication.
Cleaning standard: Wipe with lint-free cloth; avoid water and corrosive chemicals.
Inspection items: Check for wear, cracks, looseness, and abnormal noise; replace damaged seals immediately.
Pre-installation: Clean mating surfaces; inspect shaft/housing dimensions (tolerance H7/h6).
Installation process: Press-fit with a hydraulic press (avoid hammering); align axes within 0.02 mm/m.
Tightening torque: 25–30 N·m for M12 threads (ISO 898-1).
Post-installation: Check free rotation; verify no abnormal noise or friction.
Safety: Wear protective gloves; use anti-static tools in explosive environments.
