YET208-108 Eccentric Lock Take-Up Insert Bearing 38.1mm Bore Double Lip Sealed Relubricatable Bearing

1. Product Overview

YET208-108 is wide inner ring spherical outer take-up insert bearing fitted with integrated eccentric locking collar, inner bore size 38.1mm (1-1/2 inch), perfectly matched with standard T208 sliding take-up bearing housing for heavy belt conveyor tension adjustment. Suffix -108 stands for 1-1/2 inch imperial bore, designed for inch-size transmission shafts widely used in overseas large agricultural, quarry and heavy conveying equipment.

This bearing adopts DD double lip contact rubber seals on both sides and independent side grease nipple for regular supplementary lubrication. Spherical outer ring provides ±3° self-aligning compensation to offset shaft bending, housing machining tolerance and assembly misalignment. The widened inner ring is integrated with one-piece eccentric lock collar; eccentric cam forms tight interference extrusion to lock shaft firmly, effectively prevent inner ring slipping under long-term severe vibration of large grain harvesters, heavy feed conveyors and outdoor mining machinery. Internal deep groove ball structure bears combined radial load and slight bidirectional axial load, realizing stable low-friction rotary performance. Pre-filled anti-wear lithium grease inside adapts to dusty farm, mining and factory harsh workshop environments. All rolling components are fully quenched high-purity GCr15 bearing steel with ultra-precision superfinished raceway surface, featuring outstanding anti-impact and anti-abrasion performance. Widely applied to heavy grain sorting conveyors, large feed mixing equipment, heavy lawn mowers, medium mining belt conveyors and all tension roller assemblies matched with 1-1/2 inch transmission shafts.

3. Core Advantages

• YET208-108 standard 1-1/2 inch bore design, fully compatible with global imperial-size transmission shafts, perfectly meet the heavy load replacement demand of overseas large agricultural and mining conveying equipment.
• Eccentric cam locking structure forms large contact area with transmission shaft, reliable anti-slip performance under continuous strong vibration of large grain harvesters and long-distance heavy transport belt conveyors.
• DD double-sided multi-layer lip sealing construction tightly fits inner ring shoulder, effectively isolate mud, crop dust and splashing rainwater, avoid internal grease dilution and steel ball rust failure.
• Spherical outer ring self-aligning design automatically compensates assembly deviation and shaft deflection, reduce extra shaft bending stress and local abnormal bearing surface peeling wear.
• Independent side grease nipple supports on-site supplementary lubrication without complete disassembly of bearing unit, greatly shorten maintenance downtime during seasonal agricultural production peak periods.
• Fully quenched rolling elements reach HRC60–65 hardness, strong anti-indentation and contact fatigue resistance, significantly extend service life of frequently impacted heavy conveyor tension rollers.
• Spherical outer dimension consistent with metric YET208, fully interchangeable on T208 take-up housings; only inner bore is 1-1/2 inch imperial size for inch shaft assembly replacement.
• Comprehensive 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 anti-wear lithium grease.
