High-Strength Self-Lubricating Bronze Bearing | OFG61/65 Series

SHTZ – SHTNZ Round & Trimmed Flange Oilless Bushing

Product Overview

The SHTZ (Round Flange) and SHTNZ (Trimmed Flange) series are self-lubricating bearings featuring a high-strength bronze alloy base (OFG61/65) embedded with high-performance solid lubricants. Their key characteristic is an integrated mounting flange that allows for direct and secure fastening to machine structures using bolts. These two flange types are specifically engineered for applications requiring robust radial load support and moderate axial load resistance, making them the perfect choice for achieving maintenance-free operation and enhanced equipment durability.

Key Features

Completely Self-Lubricating & Maintenance-Free: The solid lubricant creates a transfer film during operation, eliminating the need for grease or oil. This is ideal for locations where lubrication is difficult, significantly reducing maintenance costs.
High-Strength Bronze Alloy Base: Offers exceptional load capacity, impact resistance, and corrosion resistance, ensuring long-term stability in heavy-duty and harsh environments.
Reliable Bolt-On Mounting: The flange is designed with mounting holes for easy installation with socket head cap screws, effectively preventing the bushing from rotating or shifting axially under vibration or impact.
Two Flange Types Available:
- SHTZ (Round Flange): Provides a standard circular mounting surface for uniform stress distribution.
- SHTNZ (Trimmed Flange): Features trimmed sides on the flange, reducing the overall mounting footprint and making it perfect for compact designs.
Precision Machining & Fit: Manufactured with a dF7 inner diameter tolerance and a Dh7 outer diameter tolerance, ensuring a precise fit with shafts and housings for smooth, low-noise operation.
