YET206-103 Eccentric Lock Take-Up Insert Bearing 31.75mm Bore Double Lip Sealed Relubricatable Bearing

1. Product Overview

YET206-103 is wide inner ring spherical outer take-up insert bearing with integrated eccentric locking collar, inner bore size 31.75mm (1-1/4 inch), perfectly matched with standard T206 sliding take-up bearing housing for belt conveyor tension adjustment. Suffix -103 represents 1-1/4 inch imperial bore, designed for inch standard transmission shafts widely used in overseas agricultural, mining and conveying equipment.
This bearing is equipped with DD double lip contact rubber seals on both sides and an independent side grease nipple for periodic supplementary lubrication. The spherical outer surface provides ±3° self-aligning compensation to eliminate shaft bending deformation, housing machining tolerance and assembly misalignment. The widened inner ring is integrated with one-piece eccentric lock collar; the eccentric cam generates tight interference extrusion to lock the transmission shaft firmly, effectively preventing inner ring slipping under long-term heavy vibration of grain harvesters, feed conveyors and outdoor heavy machinery. Internal deep groove ball structure bears combined radial load and slight bidirectional axial load, delivering stable low-friction rotary performance. Pre-filled anti-wear lithium grease inside adapts to dusty farm, quarry and factory workshop harsh operating environments. All rolling components adopt fully quenched high-purity GCr15 bearing steel with ultra-precision superfinished raceway surface, with excellent anti-impact and anti-abrasion performance. Widely applied to large grain sorting conveyors, feed mixing equipment, heavy lawn mowers, light mining belt conveyors and all tension roller assemblies matched with 1-1/4 inch transmission shafts.

3. Core Advantages

• YET206-103 standard 1-1/4 inch bore design, fully compatible with global imperial-size transmission shafts, perfectly meets the matching demand of overseas large agricultural and heavy conveying equipment.
• Eccentric cam locking structure forms large contact area with the shaft, reliable anti-slip effect under severe continuous vibration of large grain harvesters and long-distance transport belt conveyors.
• DD double-sided multi-layer lip sealing structure closely fits inner ring shoulder, effectively isolates mud, crop dust and splashing rainwater, avoids internal grease dilution and steel ball rust failure.
• Spherical outer ring self-aligning design automatically compensates assembly deviation and shaft deflection, reduces extra shaft bending stress and local abnormal bearing surface peeling wear.
• Independent side grease nipple supports on-site supplementary lubrication without complete disassembly of bearing unit, greatly shortening maintenance downtime during seasonal agricultural production peak periods.
• Fully quenched rolling elements reach HRC60–65 hardness, with strong anti-indentation and contact fatigue resistance, significantly extend service life of frequently impacted heavy conveyor tension rollers.
• Spherical outer dimension consistent with metric YET206, fully interchangeable on T206 take-up housings; only the inner bore is 1-1/4 inch imperial size for inch shaft assembly replacement.
• Comprehensive customized service: P6 high precision upgrade, stainless steel anti-corrosion version, OEM laser marking on outer ring, neutral export carton anti-rust packaging, pre-filled high-temperature anti-wear lithium grease.
