YEL205-2F Eccentric Lock Insert Bearing 25mm Bore Double 2F Flinger Seals

1. Product Overview

YEL205-2F is premium spherical outer insert bearing with integrated eccentric locking collar, metric 25mm cylindrical bore, uniquely designed with inner ring extended on both sides, matched with standard UCP/UCT/T205 bearing housings for agricultural, conveyor and light industrial equipment. The suffix 2F stands for double-sided integrated steel flinger + multi-lip contact rubber composite seal structure, delivering superior dust and splash water isolation performance compared to standard DD seals. Spherical outer ring provides ±3° self-aligning compensation to eliminate shaft bending, housing machining errors and assembly misalignment. Double-side widened inner ring effectively restricts inner ring tilt on the shaft, ensuring smoother stable rotation under continuous vibration. The integral eccentric cam locking collar generates firm interference clamping force to prevent inner ring slipping for unidirectional rotation equipment. Built-in side grease fitting supports periodic relubrication without full disassembly. Pre-filled high-viscosity anti-wear lithium grease adapts to heavy dust farm, quarry, outdoor factory harsh environments. All rolling components adopt fully quenched high-purity GCr15 bearing steel with mirror superfinished deep raceway, featuring excellent impact resistance and long service life. Widely applied to grain harvesters, feed mixers, lawn mowers, belt conveyors, packaging machinery and all 25mm metric shaft heavy vibration rotary equipment.

2. Technical Specifications

Complete metric shaft bearing housing installation drawings, medium load matching guide and long-cycle heavy dust flinger seal durability test reports can be provided upon customer request.

3. Core Advantages

• Double-side extended inner ring design restricts inner ring deflection on shafts, greatly reducing vibration and noise during continuous high-speed operation, smoother running than single-side extended YET series bearings.
• Unique 2F double steel flinger composite sealing system: outer steel flinger blocks large mud and crop debris, inner multi-lip rubber seal locks fine dust and water splash, ideal for severe outdoor dusty farm working conditions.
• Eccentric cam locking structure creates large contact area with 25mm metric shaft, reliable anti-slip performance under long-term strong vibration of grain harvesters and long-distance transport belt conveyors, specially suitable for fixed unidirectional rotation equipment.
• Spherical outer ring self-aligning function automatically compensates assembly deviation and shaft deflection, cuts extra shaft bending stress and localized abnormal bearing peeling wear.
• Independent side relubrication grease nipple allows on-site grease supplement without removing bearing unit, minimizes maintenance downtime during seasonal agricultural production peak periods.
• Fully quenched rolling elements reach HRC60–65 hardness, outstanding anti-indentation and contact fatigue resistance, extends service life of frequently impacted heavy conveyor rollers.
• Standard universal spherical outer dimension, fully interchangeable with global YEL205-2F series double extended inner ring eccentric lock insert bearings, direct replacement for all standard 205 series bearing housings without structural modification.
• Comprehensive customized service: P6 high precision upgrade, stainless steel anti-corrosion variant, OEM laser marking on outer ring, neutral export carton anti-rust packaging, pre-filled high-temperature heavy-duty lithium grease.
