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

Spacer collars in Delrin for BJ057

This kit includes four Delrin spacer collars tailored for BJ057, referenced as part number BJ057/DC. They are aimed at RC-scale models where small, precise spacers are needed to locate hubs and control axle clearance.

Delrin (acetal) is selected for its low friction and dimensional stability under hobby use, making these collars suitable where repeated assembly and sliding contact occur between hubs, bearings, or axle journals. They are locating components rather than load-bearing replacements.

Installation is straightforward for experienced hobbyists: slide the collar onto the axle or into the hub bore to achieve the desired spacing, then refit and secure the hub per the chassis instructions. Check for free rotation and correct bearing preload after fitting.

• Role: maintain axle spacing, set wheel hub position, reduce lateral freeplay.
• Material note: Delrin is ideal for sliding fits and repeated disassembly and reassembly.
• Quantity: 4 pieces supplied as shown in the product designation.
