YEL207-2F Eccentric Lock Insert Bearing 35mm Metric 2F Steel Flinger Double

1. Product Overview

YEL207-2F heavy-duty spherical outer insert bearing with integrated eccentric locking collar, standard metric 35mm cylindrical bore, double-side extended inner ring design, compatible with UCP207, UCT207 and T207 sliding take-up bearing housings for large agricultural harvesters, heavy mining conveyors and outdoor heavy industrial equipment.
Suffix `2F` stands for dual-side steel centrifugal flinger + multi-lip NBR rubber composite sealing system, far superior blocking effect against mud, crop residues and splashing rainwater compared to ordinary DD single rubber seals, specially developed for severely dusty open-air working environments.
Spherical outer ring offers ±3° self-aligning compensation to eliminate shaft bending deformation, housing machining errors and assembly offset. Double widened inner ring restricts inner ring tilt on shafts, effectively lowering operation vibration and noise during long-time continuous running. Integral eccentric cam locking collar produces stable interference clamping force to lock 35mm metric shafts tightly, preventing inner ring slipping for fixed unidirectional rotation machinery. Independent side M6 grease fitting allows regular supplementary lubrication without full disassembly of bearing unit. Pre-filled high-viscosity anti-wear lithium grease adapts to harsh farm, quarry and factory workshop conditions full of dust and moisture. All rolling components adopt fully quenched high-purity GCr15 bearing steel with mirror superfinished deep raceway, featuring outstanding impact resistance and extended service life. Widely applied to heavy grain sorting conveyors, large feed mixing equipment, heavy lawn mowers, medium quarry belt conveyors and all heavy vibration rotary devices with 35mm metric transmission shafts.

2. Technical Specifications

Complete metric shaft bearing housing installation drawings, heavy load matching guide and long-cycle heavy dust 2F flinger seal durability test reports can be provided upon customer request.

3. Core Advantages

1. Double-side extended inner ring structure limits inner ring deflection on 35mm shafts, greatly reduces vibration and running noise during continuous operation, runs much smoother than single-side widened YET series bearings.
2. Premium 2F dual steel flinger composite sealing system: outer steel flinger intercepts large mud blocks and crop stalk debris, inner multi-lip rubber seal isolates fine grain dust and splashing rainwater, optimized for harsh outdoor farm and quarry dusty conditions.
3. Eccentric cam locking design creates large contact area with 35mm metric shaft, reliable anti-slip performance under long-term strong vibration of large grain harvesters and long-distance heavy transport belt conveyors, exclusively suitable for fixed unidirectional rotation machinery.
4. Spherical outer ring self-aligning function automatically compensates assembly deviation and shaft deflection, reduces extra shaft bending stress and localized abnormal bearing surface peeling wear.
5. Independent side relubrication grease nipple supports on-site grease supplement without removing the whole bearing unit, minimizes maintenance downtime during seasonal agricultural production peak periods.
6. Fully quenched rolling elements reach HRC60–65 hardness, outstanding anti-indentation and contact fatigue resistance, significantly extend service life of frequently impacted heavy conveyor tension rollers.
7. Standard universal spherical outer dimension, fully interchangeable with global YEL207-2F series double extended inner ring eccentric lock insert bearings, direct replacement for all standard 207 series bearing housings without structural modification.
8. 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.
