8mm Linear Bushing (LM8UU/LM8LUU) Various tolerance

thingiverse

LM8LUU or 8mm Linear Bushing self lubricated. This precision-crafted linear bushing features a tolerance range from 8.2mm to 8.36mm, allowing you to select the optimal fit for your specific application. To further enhance performance and reduce friction, apply a thin layer of silicone grease or petroleum jelly-based vaseline to the inner wall of the bushing, which boasts numerous strategically designed pocket holes. For added durability and long-lasting service, consider printing this bushing with 100% infill. This will provide an exceptionally robust component that withstands the rigors of heavy use. To ensure smooth operation in dry environments, lightly spray the inner pocket holes with PTFE dry lube, preventing dust accumulation and maintaining optimal performance. This bushing is particularly well-suited for applications involving carbon fibre rods. I've also added a 55mm long version of this bushing to my Zeus X-Carriage design (Thingiverse link: https://www.thingiverse.com/thing:2817459).
