LKV208-2F Taper Bore Bearing + H2308 Sleeve, Double 2F Anti-Mud Composite Seals

1. Product Overview

LKV 208 2F tapered bore spherical insert bearing paired with H2308 withdrawal sleeve, fitted with KM8 locknut and MB8 lock washer. Double-sided 2F composite seals consist of metal centrifugal flinger plus NBR rubber lip seal. The taper sleeve delivers uniform full-circle clamping without scratching shafts. Spherical outer ring offers ±2.5° self-alignment to offset shaft installation misalignment. Dual-layer sealing blocks farm mud, crop waste, industrial dust and water splashes effectively. Built-in grease nipple supports regular relubrication. Widely used on agricultural harvesters, rotary tillers, grain sorting lines, mining conveyors, feed processing and medium construction transmission equipment.

2. Key Advantages

• Dual 2F two-stage anti-contamination seal: Metal flinger repels large mud/debris via centrifugal force; inner rubber lip blocks fine dust and moisture, outperforming single rubber seals in muddy working conditions.
• H2308 taper sleeve locking design: Even circumferential compression, stable anti-slip performance under heavy vibration and frequent forward-reverse rotation.
• ±2.5° self-aligning spherical outer ring eliminates extra stress caused by shaft deflection and assembly offset.
• Side grease fitting allows periodic supplementary lubrication for long continuous heavy-load operation.
• GCr15 fully heat-treated bearing steel delivers stable high radial load capacity.
• Standard 40mm taper bore size, fully interchangeable with single-seal LKV208+H2308 sets for direct heavy-duty upgrade.

Reduce maintenance frequency and extend equipment service life
