HPI Racing BAJA Delrin Hub Collars BJ057/DC by GPM  [BJ057/DC]

Delrin hub collars for BJ057

This aftermarket pack contains four Delrin collars made for BJ057, marked as part number BJ057/DC. They suit RC vehicles where compact, precise spacers are required to control hub position and axle clearance.

Delrin (acetal) is chosen for low friction and dimensional stability at hobby operating temperatures, so these collars work well between wheel hubs, bearings or on axle journals. They function as locating spacers rather than primary load carriers.

Fitting is simple for those with basic RC experience: slide the collar onto the axle or into the hub bore to set spacing, then refit the hub assembly following the chassis guide. Verify that the wheel spins freely and that preload is correct after installation.

• Role: hold axle spacing, position wheel hubs, minimise lateral play.
• Material note: Delrin suits sliding fits and endurance of repeated assemblies.
• Quantity: 4pcs included, as noted in the product designation.
