YAR207-2F Set Screw Insert Bearing 35mm Metric 2F Double Flinger Sealed Double Extended Inner Ring

1. Product Overview

YAR207-2F heavy-duty spherical outer insert bearing adopts dual staggered set screw locking design, standard metric 35mm bore with double extended inner ring. It matches UCP207, UCT207 and T207 take-up bearing housings for large grain harvesters, heavy belt conveyors and outdoor mining machinery.

Suffix 2F stands for dual-side steel centrifugal flinger plus multi-lip NBR composite seal, far superior in blocking mud, crop debris and splashing water than ordinary single rubber seals, ideal for heavy dust outdoor working conditions.

Spherical outer ring offers ±3° self-aligning capacity to compensate shaft deflection, housing machining errors and assembly offset. Double widened inner ring restricts inner ring shaking on 35mm shafts, cutting vibration and noise under long continuous running. Two 120° separated set screws evenly fasten the shaft, anti-slip for both forward and reverse rotation equipment. Side M6 grease fitting allows periodic refilling grease without full disassembly. Pre-filled anti-wear lithium grease adapts to dusty, humid farm and quarry environments. All rolling parts are GCr15 fully quenched bearing steel with mirror superfinished raceways, good impact resistance and long service life. Widely used on grain sorting conveyors, large feed mixers, heavy lawn mowers, quarry transport rollers and all heavy rotating equipment with 35mm metric shafts.

Metric shaft housing installation drawings, heavy load matching guide and 2F seal durability test reports are available on request.

3. Core Advantages

• Double extended inner ring reduces inner ring tilt on 35mm shafts, lower vibration and noise during continuous operation, smoother operation than single wide inner ring bearings.
• 2F double steel flinger composite seal: outer flinger blocks mud and straw waste, inner multi-lip rubber stops fine dust and splash water, perfect for farm and quarry harsh sites.
• Dual set screw locking evenly distributes clamping force, stable anti-slip performance under long strong vibration, suitable for bidirectional rotation machines.
• Self-aligning spherical outer ring offsets assembly misalignment and shaft bending, reducing local raceway peeling and shaft extra stress.
• Independent grease nipple enables on-site lubrication supplement without removing the whole bearing unit, saving maintenance time in busy farming seasons.
• Hardened rolling elements reach HRC60–65, strong anti-indentation and fatigue resistance, greatly extend service life of heavy conveyor tension rollers.
• Standard outer spherical dimension, fully interchangeable with global YAR207-2F bearings, direct replacement for all 207 series housings without modification.
• Customizable service: P6 high precision, stainless steel anti-rust version, outer ring laser OEM marking, neutral anti-rust export cartons, high temperature special grease filling.
