UYU 208 2S Vertical Insert Bearing, Double 2S Rubber Seals, Eccentric Lock

1. Product Overview

UYU 208 2S spherical outer ring insert bearing matched with vertical cast iron housings, fitted with double-sided 2S reinforced NBR rubber contact seals and eccentric locking collar on extended inner ring. Spherical outer ring provides ±2.5° self-alignment to compensate shaft assembly offset. Dual-layer rubber barrier effectively blocks heavy dust, mud splashes, crop residues and splashing water. Pre-filled high-temperature long-life grease, side grease nipple allows periodic re-lubrication. Widely applied to heavy rotary tillers, grain harvesters, heavy-duty belt conveyors, textile looms and large packaging equipment.

2. Key Advantages

• Dual 2S double lip rubber seals form double anti-pollution barrier, reduce grease leakage and extend bearing service cycle
• Eccentric lock collar provides uniform circumferential clamping force, stable anti-slip under heavy continuous vibration, fits one-way constant rotation
• Spherical outer ring eliminates extra internal stress caused by shaft installation misalignment, lower running wear and noise
• Reserved side grease fitting supports regular supplementary lubrication for long-hour non-stop heavy load operation
• Whole set GCr15 fully quenched bearing steel, excellent wear resistance and heavy radial load capacity
• Standard 40×80mm unified dimension, fully interchangeable with single-seal UYU208 insert bearings for direct upgrade

Cut maintenance frequency and improve heavy equipment long-term stable operation
