High-wear Jr HG 11mm bowl-type aluminium rollers

This replacement roller assembly is aimed at modders and restorers working on Jr HG chassis models. The bowl-type profile limits lateral contact with guard rails while the machined aluminium construction offers greater abrasion resistance than plastic alternatives. The integrated ball-race arrangement lowers rotational friction compared with plain bushings and matches common Jr HG roller mounts.

Fitting notes: use correct rollershaft length and secure each roller with the specified spacer or locknut to keep axle alignment. Verify clearances against track walls and plastic guards before running at speed. For restoration builds, the aluminium finish provides an authentic metal appearance that complements other period accessories.

Material: Aluminum
Roller diameter: 11 mm
Bearing type: Ball-race

These bowl-type aluminium ball-race rollers are a solid, low-drag solution for maintaining Jr HG models and for display-quality restorations.

How do I check compatibility with my chassis?

Measure your roller shaft diameter and the mount spacing to ensure the 11mm bore and mounting pattern will line up with your chassis.

Should I press bearings into the rollers or buy preinstalled ones?

If your supplier does not supply preinstalled bearings you can press compatible ball bearings into the bodies using a soft-faced press to avoid damage.

What maintenance keeps these rollers spinning freely?

Keep bearings and races clean, apply a small amount of light oil as required, and avoid heavy grease that attracts dust.

Do bowl rollers affect handling on short circuits?

The reduced lateral contact tends to lower snags on walls while still guiding the car, which many racers prefer on tight tracks.

Are these suitable for wet conditions?

Avoid running in heavy water without drying and cleaning the bearings afterwards, as grit and moisture will accelerate wear.

Will these improve lap times?

They reduce bearing friction compared with plain plastic rollers, which can marginally improve roll efficiency, but chassis setup will have the bigger impact on lap times.
