Spacer Sleeve

Developed for reliable service in hard-working drill rigs and hydraulic drifters, the Spacer Sleeve (OEM 3128 0494 00) is an aftermarket component used within the rock drilling machine or hydraulic drifter assembly. The cylinder provides repeatable linear movement so the connected boom, feed or auxiliary mechanism can be positioned accurately.

Precision-machined working surfaces help maintain stable movement and sealing performance during frequent extension and retraction. It provides a cost-effective alternative for maintenance programs that require dependable fit and service performance without relying solely on OEM supply. Compatible equipment for this reference includes BOOMER 104 and BOOMER 281, subject to machine configuration and serial verification.
