W208PPB2 Agricultural Spherical OD Insert Bearing, Round Bore, Triple-Lip Tri-Ply Anti-Mud Seals

1. Product Overview

W208PPB2 heavy-duty agricultural spherical outer diameter insert bearing, straight round 1-1/2 inch bore, specially developed for disc harrows, rotary tillers and field farming equipment. Equipped with one-piece integrated tri-ply three-lip shroud composite seals, forming multi-stage barrier against mud, crop residue, sand, dust and field water splash. Spherical outer ring allows ±2.5° self-alignment to compensate shaft and housing assembly misalignment. Built-in relubrication groove and grease hole support periodic grease replenishment. C3 internal clearance matches high-vibration farm working conditions, filled with high-temperature anti-wear agricultural grease for long continuous operation. Widely matched with cast iron/stamped steel housings for all kinds of soil tillage machinery.

2. Key Advantages

• Triple-lip Tri-Ply integrated shroud sealing system: Outer metal shroud blocks large mud clumps by centrifugal throw-off; three layers NBR contact lips isolate fine sand, dust and water mist, far superior anti-contamination performance vs standard 2S/2F double seals, perfectly adapted to muddy field environments.
• Spherical outer ring self-aligning structure, automatically offsets installation deflection, eliminates abnormal edge stress and premature raceway wear.
• Straight round bore design, easy press-fit installation on standard smooth farm shafts, no eccentric collar/taper sleeve required, simplifies assembly for disc harrow disc hubs.
• Extra-wide thickened inner & outer rings, larger steel ball elements, enhanced impact and heavy radial load resistance for shock-heavy tillage operations.
• Reserved internal grease channel and side grease fitting hole, convenient regular re-lubrication to extend service cycle and reduce field maintenance downtime.
• GCr15 bearing steel full quenching heat treatment, stable hardness, outstanding wear and fatigue resistance under long-hour high-vibration operation.
• Universal interchangeable cross model: DS208TT2A, 2AC08-1-1/2, 24R6-208E3, fully compatible with mainstream global farm machinery OEM standards.

8. FAQ

1. Q1: What’s the difference between W208PPB2 tri-ply 3-lip seal and ordinary 2F/2S double seals?
   Tri-ply adds an outer integrated metal shroud plus three inner rubber contact lips, multi-stage interception of mud, sand and water; 2F/2F only two layers of protection, W208PPB2 performs better in extremely muddy disc harrow working conditions.
2. Q2: What equipment is W208PPB2 most suitable for?
   Mainly matched to disc harrow disc hubs, also applicable to rotary tillers and other soil preparation machinery exposed to heavy mud and impact loads.
3. Q3: Can W208PPB2 replace DS208TT2A directly?
   Yes, all bore, outer diameter and width dimensions fully consistent, direct interchange without modifying equipment hubs.
