Hexagonal Thread Mount Precision Mini Ball Transfer Unit

Hexagonal Thread Mount Precision Mini Ball Transfer Unit

A Hex Thread Mount Mini Precision Ball Transfer Unit, also known as a ball caster or ball plunger, is a compact and precision component for gravity support and direction change. It utilizes a precision ball on top for multi-directional, low-friction rolling and sliding, and features a hex thread base for easy and secure installation into equipment. Its core characteristics are compact design, easy installation, flexible rotation, and stable load-bearing.

II. Core Structure & Working Principle

1. Ball:

• Material: Typically high-carbon chromium bearing steel (GCr15), stainless steel (e.g., 440C), ceramic (zirconia), or engineering plastic (e.g., POM).

• Process: Finely ground and polished to achieve high sphericity and very low surface roughness, ensuring smooth operation.

2. Housing & Raceway:

• Material: Matched to the ball, usually steel or engineering plastic.

• Function: Precisely encases the ball, providing support and forming a low-friction rolling track. Often contains a spring to preload the ball and ensure it returns when unloaded.

3. Body & Hex Thread:

• Material: Generally steel or stainless steel.

• Structure: The base of the body is machined with a standard hex thread (e.g., M6, M8, M10, potentially with pitch specified).

• Function: The hex design allows for easy tightening/loosening with a wrench. The thread secures the entire unit firmly into a tapped hole or nut in the mounting plate.

4. Working Principle:

• When a workpiece or equipment part rests on the ball, the ball rotates freely within its housing under load.

• Due to the ball's geometry, it converts sliding friction from any horizontal direction into its own rolling friction, significantly reducing movement resistance and enabling precise, effortless multi-directional movement.

III. Main Product Features

• Easy Installation, Secure Fixing: The hex thread design allows for simple installation and removal with just a wrench. The threaded connection provides strong anti-rotation capability and stable support.

• Low Friction, High Flexibility: The precision ball and raceway allow the unit to rotate flexibly even under load, effectively reducing equipment wear and power consumption.

• Compact Structure, Saves Space: The mini design makes it ideal for use in space-constrained equipment or precision devices.

• High Load Capacity: Despite its small size, it can withstand relatively high loads for its dimensions, thanks to the robust housing and quality materials.

• Wear-Resistant & Durable: Made from high-strength, high-wear-resistance materials for long service life, suitable for high-frequency operation.

• Multiple Material Options: Various material combinations are available to suit different environments (e.g., general industry, food, corrosive, cleanrooms).

IV. Typical Application Scenarios

This mini ball transfer unit is widely used in applications requiring precise positioning, effortless conveying, and direction change:

• Precision Instruments & Testing Equipment: Used in PCB fixtures, optical tables, measuring instrument stages for smooth movement and precise positioning of samples.

• Automation Equipment & Production Lines:

• Direction Change Mechanisms: On assembly and conveyor lines to alter the path of workpieces.

• Support & Slide Mechanisms: As feet for heavy cabinets, switchgear, machine tool tables to facilitate movement.

• Molds & Jigs: Installed under large molds or jigs for fine adjustment and positioning.

• Logistics & Conveying Systems: Used in sorters, ball transfer tables as a supplement to traditional rollers, enabling multi-directional free flow of items.

• High-End Furniture & Display Equipment: Such as sliding doors, movable display cases, TV mounts, providing a smooth moving experience.

V. Key Selection Parameters

Consider the following parameters when selecting this product:

• Thread Specification: e.g., M6x1, M8x1.25, M10x1.5, etc. (Thread Diameter x Pitch).

• Hex Size (Across Flats): e.g., 8mm, 10mm, 13mm, etc., must match the wrench.

• Ball Diameter: e.g., φ6mm, φ8mm, φ10mm, etc. A key parameter determining load capacity and flexibility.

• Total Height: The overall height after installation, affecting equipment layout.

• Static Load Capacity: The maximum safe stationary load a single unit can bear.

• Ball & Housing Material: Selected based on load, environmental requirements (humidity, chemicals, cleanliness).

• Mounting Method: Confirm if screwing into a tapped hole or passing through a clearance hole and securing with a nut.
