Other products
Sleeves are used to prevent damage to a drum. It is usually cheaper to replace a worn out sleeve in stead of replacing or repair the complete drum assembly.
The LBS split-sleeve system consists of a pair of outer shells that are bolted or welded onto a smooth drum to provide a grooving pattern. either LBS parallel grooves can be carved into sleeves. As with all LBS drums, the grooving in split sleeves is engineer to much the specific rope construction, diameter and length, and to suit
We can design the LBS sleeve according to the drum's size and parameter.So the customer need to provide some paramter as follows:
| The drum's outer diameter | LBS sleeves diameter |
| Width between the flanges | 320mm 550mm or as your requirement |
| The rotation direction | Left or right |
| Wire rope diameter and structure | 22mm 33mm or any others |
| The material | Q345B or high strength steel |
| The surface hardness | As your requirements |
