The IKO POSB12A is a precision male-threaded rod end spherical plain bearing engineered for high radial loads, angular misalignment compensation, and reliable linkage motion control. As a premium IKO rod end bearing, this POSB12A model features a robust one-piece housing, self-aligning spherical sliding contact, and a lubrication port for extended service, making it a preferred component for industrial linkages, automation systems, and mechanical control mechanisms.
In full compliance with ISO 12240‑1 and IKO standard specifications, precise dimensional parameters are: bore 12 mm, outer diameter 30 mm, bearing width 12 mm, thread M12×1.75 (right‑hand), minimum chamfer 0.3 mm, tolerance class PN (Normal), weight 0.085 kg, dynamic radial load 13.0 kN, static radial load 17.3 kN, allowable misalignment angle ±7°.
All structural components use high‑performance bearing materials. Inner ring and outer housing are manufactured from GCr15 (100Cr6) high‑carbon chromium bearing steel, hardened to HRC 60–64, delivering exceptional wear resistance, contact fatigue strength, and dimensional stability. The housing is zinc‑plated for corrosion protection; the sliding surface features MoS₂ coating for low friction and dry‑running capability.
Key manufacturing processes include precision hot forging, CNC machining, vacuum hardening and tempering, spherical grinding, and superfinishing. Strict geometric control ensures smooth sliding, minimal friction, and consistent self‑aligning performance for the IKO POSB12A bearing.
Calculated per ISO 281, the L10 basic rated life exceeds 18,000 hours under standard lubrication and rated load. Service life is influenced by load level, alignment accuracy, lubrication interval, contamination, and operating temperature.
This IKO POSB12A rod end bearing serves automation machinery, machine tools, packaging equipment, textile machines, automotive linkages, and construction machinery. Its self‑aligning design, high load capacity, and threaded mounting make it ideal for linkage and control systems requiring angular compensation and stable transmission.
For maintenance, use NLGI 2 lithium complex grease; fill 30%–40% of cavity volume via the lubrication hole, relubricate every 450 operating hours. Keep sliding surfaces clean; inspect noise, vibration, and torque periodically; replace if excessive wear or binding occurs.
Before installation, clean threads and mating surfaces; use standard wrenches to avoid over‑tightening. Ensure alignment error within 0.05 mm; confirm free articulation after mounting. Conduct a no‑load test to verify smooth operation, preventing premature failure from improper installation.
