LKU205-2F Taper Bore Insert Bearing + H2305 Adapter Sleeve, Double 2F Anti-Mud Composite Seals

1. Product Overview

LKU 205 2F tapered bore spherical insert bearing matched with H2305 withdrawal sleeve, equipped with KM5 locknut and MB5 lock washer. Double-sided 2F composite seals adopt centrifugal metal flinger + NBR rubber lip two-stage barrier. The 1:12 taper sleeve delivers uniform full-circle clamping without scratching shaft surfaces. Spherical outer ring provides ±2.5° self-alignment to offset shaft assembly misalignment. Dual-layer sealing blocks light mud, crop dust, industrial fine powder and water splashes efficiently. Side grease nipple supports regular relubrication, widely applied to small agricultural machines, mini grain sorting lines, light conveyors, miniature feed processing and light transmission equipment.

2. Key Advantages

1. Dual 2F anti-contamination seal: Metal flinger throws light mud and debris away via centrifugal force; inner rubber lip isolates fine dust and moisture, outperforming single 2S rubber seals in dusty, slightly muddy environments.
2. H2305 taper sleeve locking design: Even circumferential compression, stable anti-slip performance under light vibration and frequent forward-reverse rotation.
3. ±2.5° self-aligning spherical outer ring eliminates extra internal stress caused by shaft deflection and assembly offset, reducing abnormal bearing wear and noise.
4. Side grease fitting enables periodic supplementary lubrication to extend service cycle and cut maintenance downtime.
5. GCr15 fully heat-treated bearing steel with stable light-medium radial load capacity.
6. Standard 25mm taper bore size, fully interchangeable with single-seal LKU205+H2305 sets for direct heavy-duty sealing upgrade.

Reduce maintenance frequency and extend service life of small equipment
