YAR206-2F Set Screw Insert Bearing 30mm Metric 2F Double Flinger Sealed Double Extended Inner Ring

1. Product Overview

YAR206-2F heavy-duty spherical outer insert bearing features dual set screw locking design, standard metric 30mm cylindrical bore and double-side extended inner ring structure. It perfectly matches UCP206, UCT206 and T206 sliding take-up bearing housings for grain harvesters, medium-heavy conveyors and outdoor farm machinery.

Suffix `2F` refers to double-sided steel centrifugal flinger + multi-lip NBR rubber composite sealing structure. It delivers superior resistance against mud, crop residues and splashing rainwater compared with ordinary single rubber seals, specially designed for heavily dusty farm and open-air workshop working environments.

Spherical outer ring provides ±3° self-aligning compensation to offset shaft bending deformation, housing machining tolerances and assembly misalignment. Double widened inner ring limits inner ring deflection on 30mm shafts, effectively cutting vibration and running noise during long-time continuous operation. Two 120° staggered set screws clamp the shaft evenly to stop inner ring slipping, suitable for both forward and reverse rotation equipment. Independent side M6 grease fitting allows regular supplementary lubrication without fully disassembling the bearing unit. Pre-filled high-viscosity anti-wear lithium grease adapts to humid, dusty outdoor conditions. All rolling components adopt fully quenched GCr15 bearing steel with mirror superfinished raceways, featuring stable impact resistance and long service life. Widely used on grain sorting conveyors, feed mixing machines, medium heavy lawn mowers, medium quarry belt conveyors and all medium-heavy rotary equipment with 30mm metric shafts.

Metric shaft bearing housing installation drawings, medium-heavy 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 restricts inner ring tilt on 30mm shafts, greatly reduces vibration and running noise during continuous operation, runs smoother than single-side widened insert bearings.
• Upgraded 2F dual 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, ideal for harsh outdoor farm and quarry environments.
• Double staggered set screw locking evenly distributes clamping force on 30mm metric shafts, stable anti-slip performance under long-term vibration, applicable to both unidirectional and bidirectional rotation machinery.
• Spherical outer ring self-aligning function automatically compensates assembly deviation and shaft deflection, reduces extra shaft bending stress and local raceway peeling wear.
• Independent side relubrication grease nipple supports on-site grease replenishment without removing the whole bearing unit, minimizing maintenance downtime during peak agricultural production seasons.
• Fully quenched rolling elements reach HRC60–65 hardness, excellent anti-indentation and contact fatigue resistance, extending service life of medium-heavy conveyor tension rollers.
• Standard universal spherical outer dimension, fully interchangeable with global YAR206-2F series double extended inner ring set screw insert bearings, direct replacement for all standard 206 series bearing housings without structural modification.
• Complete customization 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.
