1. Product Overview

YET205 is wide inner ring spherical outer insert bearing fitted with eccentric locking collar, inner bore size 25mm, designed exclusively for T205 sliding take-up housings used on conveyor tension systems. It is equipped with DD double-lip contact rubber seals on both sides and a side-mounted grease nipple for periodic relubrication.

The spherical outer surface enables ±3° self-aligning compensation to eliminate installation deviation, shaft bending and housing machining errors. The widened inner ring integrates a one-piece eccentric lock collar; the eccentric cam generates interference pressure to firmly lock the transmission shaft and stop inner ring slipping under continuous heavy vibration from agricultural and conveying equipment. The internal deep groove ball structure supports combined radial load and minor bidirectional axial load, delivering stable low-friction rotary performance. Pre-filled anti-wear lithium grease is housed inside, making it ideal for dusty outdoor farm, quarry and factory conveying environments. All rolling components are manufactured from fully quenched GCr15 bearing steel with ultra-smooth superfinished raceways, offering outstanding impact and abrasion resistance. Widely applied to grain sorting conveyors, feed mixing equipment, lawn harvesters, light mining belt conveyors and all types of vibration-prone tension roller assemblies.

3. Core Advantages

• Eccentric cam locking mechanism creates large contact area with the shaft, delivering reliable anti-slip performance under severe vibration from crop harvesters and long-distance transport conveyors.
• DD double-sided multi-layer lip sealing construction tightly fits the inner ring shoulder, effectively isolating mud, crop dust and water splashes to prevent grease dilution and steel ball corrosion.
• Spherical outer ring self-aligning design automatically offsets assembly misalignment and shaft deflection, reducing extra bending stress on the shaft and localized abnormal bearing wear.
• Independent side grease nipple allows on-site lubrication without full bearing disassembly, cutting maintenance downtime during seasonal agricultural production peaks.
• Fully quenched rolling elements reach HRC60–65 hardness, featuring strong indentation and fatigue resistance to extend service life of frequently impacted conveyor rollers.
• Compact one-piece insert structure enables simple press-fit assembly into standard T205 take-up housings, streamlining mass production line assembly workflows.
• Standard universal spherical outer dimension, fully interchangeable with global YET205 series eccentric lock take-up bearings; no structural modification required during spare part replacement.
• Customization options: 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 anti-wear lithium grease.
