Product Datasheet: 330180-50-05
1. Product Overview & Description
The 330180-50-05 is a heavy-duty, self-lubricating plain linear bushing (sleeve bearing). Designed for high-load applications and harsh environments, it provides reliable linear motion for piston rods, guide posts, and shafts without the need for external lubrication in many cases. Its robust construction ensures long service life and stable operation under demanding conditions.
2. Key Features & Highlights
High Load-Bearing Capacity: Designed to withstand high radial loads, making it suitable for heavy machinery.
Self-Lubricating Liner: Features an inner liner (e.g., PTFE composite) that provides a low-friction surface, reducing wear on the mating shaft.
Corrosion & Contamination Resistant: The outer shell and liner material are resistant to corrosion, wear, and many chemicals.
Maintenance-Free Operation: Ideal for applications where lubrication is difficult or undesirable.
Easy Installation: Simple press-fit design allows for quick and easy installation into a housing bore.
