YAR205-2F Set Screw Insert Bearing 25mm Metric 2F Double Flinger Sealed Double Extended Inner Ring

1. Product Overview

YAR205-2F heavy-duty spherical outer insert bearing adopts double set screw locking design, standard metric 25mm cylindrical bore, double-side extended inner ring structure, compatible with UCP205, UCT205 and T205 sliding take-up bearing housings for grain harvesters, medium conveyor equipment and outdoor agricultural machinery.
Suffix `2F` represents double-sided steel centrifugal flinger + multi-lip NBR rubber composite sealing structure, with stronger blocking performance against mud, crop residues and splashing rainwater compared to ordinary single-layer rubber seals, specially designed for severely dusty farm and open-air workshop environments.
Spherical outer ring offers ±3° self-aligning compensation to offset shaft bending deformation, housing machining errors and assembly misalignment. Double widened inner ring limits inner ring deflection on 25mm shafts, effectively reducing vibration and noise during long-term continuous operation. Two staggered set screws evenly clamp the transmission shaft, effectively preventing inner ring slipping, suitable for both forward and reverse rotation equipment. Independent side M6 grease fitting supports regular supplementary lubrication without complete disassembly of the bearing unit. Pre-filled high-viscosity anti-wear lithium grease adapts to humid and dusty outdoor working conditions. All rolling parts are made of fully quenched GCr15 bearing steel with mirror superfinished raceways, featuring stable impact resistance and long service life. Widely used in grain sorting conveyors, feed mixing equipment, medium lawn mowers, small and medium quarry belt conveyors and all medium-load rotating equipment equipped with 25mm metric shafts.

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

3. Core Advantages

• Double-side extended inner ring structure restricts inner ring tilt on 25mm shafts, greatly lowers vibration and running noise during continuous operation, operates more smoothly than single-side widened insert bearings.
• Upgraded 2F double steel flinger composite sealing system: outer steel flinger blocks large mud blocks and crop stalk debris, inner multi-lip rubber seal isolates fine dust and splashing rainwater, perfectly adapted to harsh outdoor farm and quarry working conditions.
• Double staggered set screw locking evenly distributes clamping force on 25mm metric shafts, stable anti-slip effect under long-term vibration, applicable to both unidirectional and bidirectional rotation equipment.
• Spherical outer ring self-aligning design automatically compensates assembly deviation and shaft deflection, reduces extra shaft bending stress and local raceway peeling wear.
• Independent side relubrication grease nipple allows on-site grease replenishment without removing the entire bearing unit, cutting maintenance downtime during peak agricultural production seasons.
• Fully quenched rolling elements reach HRC60–65 hardness, excellent anti-indentation and contact fatigue resistance, extending the service life of medium-load conveyor tension rollers.
• Standard universal spherical outer dimension, fully interchangeable with global YAR205-2F series double extended inner ring set screw insert bearings, directly replaceable for all standard 205 series bearing housings without structural modification.
• Complete 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 heavy-duty lithium grease.
