Overview

• Manufacturer: John Deere (OEM component identified as AZ49176).
• Part type: Double‑row angular contact ball bearing with seals on both sides (RS), designed for high radial and axial load handling.
• Cross reference: SKF 3205 A‑2RS1/C3 (standardized designation for the same bearing geometry).
• Dimensions (Bore x Outer Ø x Width): 25 mm x 52 mm x 20.6 mm.
• Typical use: Used in John Deere drive/implement assemblies where a compact, sealed, high‑load bearing is required, such as idler/pulley and drive components in agricultural equipment.

Key Features

• Part Number: AZ49176
• Type of machine suitable for: John Deere agricultural equipment and compatible drive/implement assemblies requiring a 25x52x20.6 mm angular contact ball bearing with two‑sided seals.
• Installation tips:
  • Confirm bore diameter (25 mm) matches shaft; clean mating surfaces and inspect for damage before fitting.
  • Use proper pressing methods to seat the bearing squarely; avoid hammering or shaft misalignment.
  • Inspect RS seals for integrity; replace if damaged during installation to maintain contamination resistance.
  • Apply recommended lubrication per equipment manual if applicable; ensure correct orientation in the housing to preserve seal performance.
• Key performance notes: Sealed design reduces ingress of dust and moisture; double‑row configuration provides enhanced load capacity for mixed radial/axial loading scenarios.

Compatibility

• Suitable machine models: John Deere equipment that specifies AZ49176 or uses a 25×52×20.6 mm angular contact bearing in drive/idle/implement assemblies.
• Alternative part numbers / cross references: AZ64070, DE19311; SKF 3205 A‑2RS1/C3 (same bearing family and dimensions).
• Notes on cross‑references: Cross‑reference parts are commonly stocked as replacements in JD service parts catalogs and aftermarket suppliers; verify exact fitment with your JD OEM guide or bearing cross‑reference when replacing.
