Technical overview for DB-02 bearing replacement

The JAZRIDER Metal Shielded RC Ball Bearing Set supplies 28 bearings intended to replace common friction points on the Tamiya DB-02 chassis. These metal shielded bearings are specified to reduce drag and provide reliable rotational behaviour under normal hobby use.

Exact bearing breakdown

The kit contains the following precision sizes for direct or near-direct replacement of stock bushings and bearings:

  • 3 x 7 x 3mm - 2 pieces
  • 4 x 8 x 3mm - 1 piece
  • 5 x 8 x 2.5mm - 4 pieces
  • 5 x 10 x 4mm - 17 pieces
  • 10 x 15 x 4mm - 4 pieces

Field use and service guidance

Metal shielded bearings combine a good balance of protection and reduced rolling resistance. For routine service, inspect for sideplay and contamination, apply a light bearing oil when needed, and replace bearings showing wear to maintain drivetrain efficiency.

Which components on the DB-02 benefit most from these bearings?

Wheel hubs, transmission shafts and idler points typically see the greatest improvement when upgraded from bushings or worn bearings to the sizes supplied in this set.

What installation practices protect bearing life?

Use a straight press or correctly sized driver, avoid hammering, ensure housings are free of burrs, and do not force bearings at an angle. Correct seating preserves inner race alignment and longevity.

How should I evaluate bearing condition during inspections?

Check for roughness, play, or noise when spun by hand. Any grinding, lateral movement, or binding indicates replacement is required to avoid drivetrain wear.
