IKO LMK6LUU is a precision long‑type square‑flange linear ball bearing engineered for smooth low‑friction linear motion, high rigidity, and stable positioning in compact automation equipment. Built to ISO 14728 linear motion standards, this bearing delivers consistent performance, easy mounting, and extended service life for precision machinery.
Bore (d): 6 mm; Outer diameter (D): 12 mm; Overall length (L): 35 mm; Maximum chamfer (r): 0.3 mm; Flange square size: 22 mm; Flange thickness: 5 mm. Tolerance class: ISO Normal (P0); Radial clearance: 5–15 μm; Mass: 0.03 kg.
Outer tube & raceways: GCr15 (SUJ2) high‑carbon chromium bearing steel (HRC 60–64), offering high hardness, excellent wear resistance, and strong rolling fatigue life. Rolling elements: GCr15 precision steel balls for stable motion. Cage: reinforced polyamide 66 (PA66), ensuring low noise, high heat resistance, and stable ball guidance. Seals: NBR nitrile rubber for effective dust and grease retention.
Cold extrusion forms high‑density blank structure; CNC turning ensures dimensional accuracy; vacuum heat treatment delivers uniform hardness and minimal deformation; precision cylindrical grinding controls geometry; superfinishing achieves raceway roughness Ra ≤ 0.02 μm to reduce friction and extend life.
Basic rating life calculated per ISO 14728; standard operating conditions yield nominal travel life ≥100,000 meters or ≥3,000 operating hours. Key influencing factors: lubrication condition, contamination, alignment accuracy, load level, and operating temperature.
Suitable for 3D printers, small CNC machines, semiconductor equipment, medical devices, automation modules, textile machinery, and precision measuring instruments. Its square flange, long body, and compact size enable stable anti‑moment load performance and easy installation in limited spaces.
Routine inspection every 1,000 operating hours or 6 months; lubricate with lithium‑based grease (NLGI No.2); fill 30%–40% of internal space; clean with lint‑free cloth and non‑corrosive solvent; check for abnormal noise, heat, or play; replace bearing if seizure, excessive clearance, or seal damage occurs.
Clean housing and shaft before mounting; press evenly with special tools (avoid direct impact); alignment error ≤0.01 mm/mm; tighten flange bolts to 1.2–1.5 N·m; post‑installation test smooth travel and temperature rise ≤40°C above ambient; wear protective gloves and ensure dust‑free conditions.
