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

Precision Delrin collars for BJ057 use

This upgrade pack contains four Delrin collars sized for BJ057 applications and identified as part number BJ057/DC. These components provide accurate axial location for hubs and bearings where compact spacers are required on RC vehicles.

Delrin (acetal) is specified for its low coefficient of friction and dimensional stability across typical operating temperatures, making it suitable for spacer duties between wheel hubs, bearings, or axle journals. The collars are engineered as positioning elements rather than primary structural or load-bearing parts.

Installation follows standard hub service practice: position the collar on the axle or into the hub bore to set the required offset, then reassemble the hub per chassis procedure. Post-fit checks should verify unobstructed rotation and correct bearing preload to ensure reliable operation.

• Role: establish and retain axle spacing, accurately locate wheel hubs, reduce lateral play.
• Material note: Delrin offers predictable sliding behaviour and supports repeated removal and refit cycles without rapid wear.
• Quantity: 4 pieces supplied as detailed by the part number.
