Buying Guide

Match bearing size to spindle

Confirm inner diameter, outer diameter, and width (e.g., 35x80x21mm) to ensure a precise press-fit on your mower spindle

Prefer double rubber seals for decks

Double rubber (2RS) seals keep grease in and debris out, reducing maintenance on exposed mower deck spindles

Check pack quantity for rebuilds

Multi-pack bearings like 10-piece sets lower per-unit cost and are practical if you service multiple spindles or keep spares

Consider bearing tolerance and load type

Choose bearings rated for radial loads typical of blades and compatible with your spindle's speed and thrust demands

Verify material and corrosion resistance

Look for hardened steel races and corrosion-resistant seals when blades and wet grass expose components to moisture
