Overview
CGR's Ball Transfer Units (BTUs) are designed for effortless, multi-directional load transfer, suitable for various industrial applications. These units facilitate the movement of items precisely and efficiently.

Standard Features
The BTUs feature a shell and housing made from pressed steel with zinc plating for enhanced durability. They are available in different models with variations in ball materials, including carbon steel, stainless steel, and polyacetal (POM) with steel.

Applications in Mechanical Engineering
BTUs are ideal for smooth, linear assembly and manufacturing operations, such as feeder tables for metal machining, drill stands, die-stamping, and tool changing. They are also used in delivery mechanisms for steel banding machines and conveyor units for heavy mechanical work.

Applications in Handling and Delivery Systems
BTUs are utilized in ball tables, turntable units, and crossing points in conveyor equipment. They are essential in airports for cargo and baggage handling, as well as in parcel/package sorting systems. They enable precise and smooth maneuvering of sheet metals and tubing.

Industries Using BTUs
BTUs are employed by airplane equipment manufacturers, nuclear reactor constructors, and the food-processing and building materials industries.

Pressed Steel Range - BPT
This range features housing and cover in pressed steel with zinc plating, a bearing cup in zinc plated treated steel, and is sealed by a felt disk. It is available in models with carbon steel balls, stainless steel balls, and polyacetal (POM) load balls.

Heavy-Duty Range - BPM
The BPM range includes solid steel housing with a black oxide finish or zinc plating for stainless steel balls. It has a low, sloping profile for increased shock resistance and is sealed by a felt disk. It is designed to withstand heavy loads and includes a standard groove for snap ring fixing.

Technical Specifications
The document provides detailed specifications for various models, including load capacity (in daN), dimensions (in mm), and weight (in g). Models are categorized under BPT and BPM types, with specific references for each version (carbon steel, stainless steel, and polyacetal).
