Radial Insert Ball Bearing ES206 Eccentric Collar 30x62x35.7mm for Agricultural and Conveyor Machinery
Product Overview
The ES206 Radial Insert Ball Bearing is a heavy-duty, self-aligning bearing unit equipped with a zinc-plated eccentric locking collar and dual lip seals. Engineered to support predominantly radial loads while compensating for initial static shaft misalignment, it is widely used in agricultural machinery, belt conveyors, and packaging lines where fast installation and reliable contaminant protection are essential.
Technical Specifications
Model: ES206 (Interchangeable with SA206 / YET206 / AEL206)
Inner Diameter (ID): 30 mm
Outer Diameter (OD): 62 mm
Width: 35.7 mm (Total Width with Collar) / 23.8 mm (Inner Ring) / 18 mm (Outer Ring)
Structure: Single Row Radial Insert Ball Bearing with Eccentric Locking Collar
Eccentric locking collar ensures rapid, secure shaft mounting without requiring tight shaft tolerances or complex machining.
Spherical outer ring design automatically compensates for static misalignment when mounted in matching pillow block or flanged housings.
Dual lip seals with metal flingers block dust, crop residue, and moisture while retaining factory-filled high-grade grease.
Relubricatable outer ring features an annular groove and lubrication holes for easy maintenance and extended service life.
Custom material and coating options available (such as stainless steel or anti-corrosion zinc plating) for harsh environments.
Quality Control
Raw material inspection: Ultrasonic flaw detection and chemical composition verification of bearing-grade chrome steel.
Precision machining process: CNC precision grinding of spherical outer diameters and deep raceways.
Heat treatment control: Automated quenching and tempering for maximum wear and fatigue resistance.
Clearance & rotation testing: 100% verification of radial internal clearance, grease fill volume, and seal drag.
FAQ
Q1: Can you provide custom insert bearings or complete housing units?Yes, we support OEM and custom production based on drawings, and we can supply the ES206 pre-mounted in cast iron or pressed steel housings (such as P206, F206, or FL206).
Q2: How does the eccentric locking collar work on the ES206?The eccentric collar fits over the matching eccentric extension of the inner ring. Turning the collar in the direction of shaft rotation locks the bearing firmly onto the shaft, which is then secured by tightening the set screw.
Q3: Is the ES206 interchangeable with SA206, YET206?Yes, all these models share the exact same boundary dimensions (30×62×35.7 mm) and eccentric locking collar mechanism, making them directly interchangeable across standard applications.
Q4: What quality certifications do your bearings hold?Our manufacturing facilities operate strictly under ISO 9001 and IATF 16949 quality management standards to ensure full traceability and consistent industrial quality.
Q5: What are your shipping terms and delivery times?We support EXW, FOB, CIF, and DDP terms via sea, air freight, or international express. Standard models ship within 7–15 days, while custom batches take 25–45 days.
