How to Identify Your Mower Spindle Bearing

1. Check the OEM Number:

Most bearings have a stamped number (e.g., 6203-2RS). You can also refer to your mower’s manual or parts diagram.

2. Measure Bearing Dimensions:

Use a caliper to measure inner diameter (ID), outer diameter (OD), and width. Common mower bearing sizes include:

  • 6203: 17x40x12 mm
  • 6204: 20x47x14 mm
  • 6205: 25x52x15 mm
  • 6206: 30x62x16 mm

4. Choose the Right Seal Type:

  • 2RS → Double rubber sealed (best for dusty/muddy conditions)
  • ZZ → Double metal shielded (good for high-speed applications)

Signs of Worn Spindle Bearings

  • Unusual grinding or squealing noise while mowing
  • Blades wobble or vibrate excessively
  • The mower deck doesn’t cut evenly
  • Resistance when manually rotating the spindle pulley

If you notice any of these symptoms, inspect and replace your spindle bearings before they cause damage to the spindle housing or mower blades.

Replacing Mower Spindle Bearings

  1. Remove the mower deck and detach the spindle assembly.
  2. Use a bearing puller or press to remove the old bearings.
  3. Clean the housing and check for damage or corrosion.
  4. Press in the new bearings gently using a bearing driver or socket.
  5. Reassemble the spindle, ensuring seals are intact and pulleys rotate freely.

Recommended High-Quality Replacement Bearing Brands

  • Peer Bearings – OEM-quality replacements used by John Deere and Scag.
  • NTN – Long lifespan with precision sealing technology.
  • Nachi – Known for heat resistance and durability in tough mowing conditions.
  • Timken – Premium-grade steel bearings with reliable load capacity.
  • Oregon/Stens – Affordable aftermarket solutions that fit most mower models.

FAQs

What size are most mower spindle bearings?

Most common sizes are 6203-2RS (17x40x12 mm) and 6204-2RS (20x47x14 mm), though some larger decks use 6205 or 6206 bearings.

Can you grease sealed spindle bearings?

No, 2RS or ZZ bearings are sealed and do not require greasing. However, ensure your spindle housing’s grease fittings are serviced if your model allows.

How long do mower spindle bearings last?

With proper care and lubrication, they typically last 3–5 years, depending on mowing frequency and conditions.

Can I replace spindle bearings without replacing the whole spindle?

Yes. If the housing and spindle shaft are in good shape, you can just replace the bearings to save costs.

Are all 6203 bearings the same?

While dimensions are identical, quality and seal type vary by brand. Choose a reputable manufacturer for longer performance.
