OEM 3115505900 垫圈 Epiroc COP 1838HD COP 2238HD Atlas Copco 采矿设备零件 3115 5059 00

Keeps oil in and contaminants out. Built for life on a drill rig.

The 3115505900 washer sits inside the gearbox of Epiroc COP 1838HD, 2238HD, and Atlas Copco drifters. It’s a simple steel ring — but if it fails, you’re looking at oil leaks, dirt ingress, and unnecessary downtime. This one is made to hold its shape under impact, vibration, and thermal cycling so your gearbox stays sealed.

Direct swap for OEM part numbers 3115505900 / 3115 5059 00. Fits COP 1638HD+, 1838HD, 1838HD+, 2238HD, 2238HD+.

FAQ
FAQ
Is this an original Epiroc part or aftermarket?
It’s OEM — manufactured to Epiroc’s specs, not a generic copy.
Will this washer work in both COP 1838HD and 2238HD?
Yes. Epiroc uses the same part number across the COP 1638HD+, 1838HD, 1838HD+, 2238HD, and 2238HD+. Always double-check your parts book, but it’s designed as a direct replacement.
How quickly can I get it on site?
We hold stock. Standard air freight takes 5–10 business days. If the rig is down and you need it faster, ask about express shipping.
What if my drifter is an older Atlas Copco model, not an Epiroc?
Same part. The 3115505900 washer was used on Atlas Copco-branded COP series drifters before the name changed to Epiroc. Send us your serial number and we’ll confirm it before we ship.
Does this washer come with any warranty?
12 months against manufacturing defects. If it’s installed to the torque specs in the service manual and fails under normal use, we’ll replace it.
