Overview

This document provides detailed technical specifications and component descriptions for various types of spherical bushing sets, including rhomboid flange type, inner ring flange bushings, and inner ring straight bushings. The products include versions with gray cast iron and stainless steel cases, some of which are built-to-order.

Product Types and Materials

• Cases: Gray cast iron (FC200) and stainless steel (SCS13). Stainless steel cases (DUFBS, DUSBS, PUFBS, PUSBS) are built-to-order.
• Inner Rings: Made of S45C steel with non-electrolytic nickel plating.
• Outer Rings: Bronze with graphite, oilless type (SO#50SP2).
• Set Screws: Hexagon socket head, made of SCM435 steel. Quantity varies (4 for flange bushings, 2 for straight bushings).
• Stopper Pin: SUJ2 material, one piece attached to the outer ring.

Component Tables and Dimensions

The document includes detailed tables listing dimensions and quantities for components across different catalog numbers and sizes. Key parameters include:

• Dimensions such as inner diameter (d), outer diameter, flange thickness, length, bolt size, and mounting bolt specifications.
• Values in parentheses indicate measurements for stainless steel cases.
• Mounting bolt sizes range from M10 to M16 depending on the catalog number.

Product Variants

• Inner Ring Flange Bushings: PUFBF (gray cast iron), PUFBS (stainless steel), DUFBF (gray cast iron), DUFBS (stainless steel).
• Inner Ring Straight Bushings: PUSBF (gray cast iron), PUSBS (stainless steel), DUSBF (gray cast iron), DUSBS (stainless steel).

Additional Features and Notes

• Grease nipples are provided for lubrication.
• Stopper pins are attached to the outer ring to prevent rotation.
• Oilless design with bronze and graphite outer rings enhances maintenance-free operation.
• RoHS compliance is indicated.

Summary of Critical Specifications

• Material selection ensures durability and corrosion resistance (stainless steel options available).
• Precise dimensional data supports correct mounting and compatibility.
• Built-to-order stainless steel cases allow customization for specific applications.
• Hexagon socket head set screws secure components firmly.
• Stopper pins enhance operational safety by preventing unwanted movement.
